• Designed on Atmel MG1140E matrix and packaged into MQFPL196 Description and Applications The TSS901E provides an interface between a Data-St robe link - according to the IEEE Std 1355-1995 specification carrying a simple interprocessor communication protocol - and a data processing node consisting of a CPU and a communication and data memory. The TSS901E offers hardware supported execution of the major parts of the interpro- cessor communication protocol: data transfer between two nodes of a multi-processor system is performed with minimal host CPU intervent ion. The TSS901E can execute simple commands to provide basic features for syste m control functions; a provision of fault tolerant features exists as well. Although the TSS901E initial exploitation is for us e in multi-processor systems where the high speed links standardisation is an importan t issue and where reliability is a requirement, it could be used in applications such as heterogeneous systems or mod- ules without any communication feature like special image compression chips, some signal processors, application specific programmable logic or mass memory. The TSS901E may also be used in single board system s where standardised high speed interfaces are needed and systems containing "non-intelligent" modules such as A/D-converter or sensor interfaces which can be assembled with the TSS901E thanks to the "control by link" feature.

• transfer of data between two modes of a multi-proc essor system with minimal host CPU intervention,
• execution of simple commands to provide basic feat ures for system control functions,
• provision of fault tolerant features. However, with disabling of features such as the pro tocol handling or with reduction of the trans- mit rate (TSS901E automatically reduces transmit ra te for sending null tokens) also low power usage is supported.

• bidirectional link channels , all comprising the DS-link macro cell (DSM), receive and transmit sections (each including FIFOs) and a protocol processing unit (PPU). Each channel allows full duplex communication up to 200 Mbit/s in each direction. With protocol command execution a higher level of communication is supported. Link disconnect detection and parity check at token level are performed. A checksum generation for a check at packet level can be enabled. The transmit rate is selectable between 1.25 and 20 0 Mbit/s; an additional power saving mode can be enabled, where the transmit rate is aut omatically reduced to 10 Mbit/s when only Null tokens are being transmitted over the lin k. The default transmit rate is 10 Mbit/s. For special applications the data transmit rate can be programmed to values even below 10 Mbit/s; the lowest possible (to be within the IEEE- 1355 specification) transmit rate is 1.25 Mbit/s (the next values are 2.5 and 5 Mbit/s).
• Communication Memory Interface (COMI) performs autonomous accesses to the communication memory of the module to store data received via the links or to read data to be transmitted via the links. The COMI consists of individual memory address generators for the receive and transmit direction of every DS link channel. The access to the memory is controlled via an arbitration unit providing a fair arbitration scheme. Two TSS901E can share one DPRAM without external arbitration. The data bus width is scalable (8/16/32 bit) to allow flexible integration with any CPU type. Operation in little or big endian mode is configurable through internal registers. The COMI address bus is 16 bit wide allowing direct access of up to 64K words of the DPRAM. Two chip select signals are provided to allo w splitting of the 64k address space in two memory banks.
• Host Control Interface (HOCI) gives read and write access to the TSS901E configuration registers and to the DS-link channels for the controlling CPU. Viewed from the CPU, the interface behaves like a peripheral that generates acknowledges to synchronize the data transfers and which is located somewhere in the CPU's address space. Packets can be transmitted or received directly via the HOCI. In this case the Communica- tion Memory (DPRAM) is not strictly needed. However , in this case the packet size should be limited to avoid frequent CPU interaction. The data bus width is scalable (8/16/32 bit) to all ow flexible integration with any CPU type. The byte alignment can be configured for little or big endian mode through an external pin. Additionally the HOCI contains the interrupt signal ling capability of the TSS901E by provid- ing an interrupt output, the interrupt status regis ter and interrupt mask register to the local CPU. A special pin is provided to select between control of the TSS901E by HOCI or by link. If control by link is enabled, the host data bus funct ions as a 32-bit general purpose interface (GPIO).
• Protocol Command Interface (PRCI) that collects the decoded commands from all PPUs and forwards them to external circuitry via 5 special pins.
• JTAG Test Interface that represents the boundary scan testing provisions specified by IEEE Standard 1149.1 of the Joint Testing Action Group (JTAG). The TSS901E' test access port and on-chip circuitry is fully compliant with the IEEE 1149.1 specification. The test access port enables boundary scan testing of circuitry connected to the TSS901E I/O pins. Operation Modes According to the different protocol formats expected for the operation of the TSS901E, two major operation modes are implemented into the TSS901E. The operation modes are chosen individu- ally for each link channel by setting the respective configuration registers via the HOCI or via the link.

• Transparent Mode (default after reset): This mode allows complete transparent data transfer between two nodes without performing any interpretation of the databytes and without generating any acknowledges. It is completely up to the host CPU to interpret the received data and to generate acknowledges if required. The TSS901E accepts EOP1 and EOP2 control tokens as packet delimiters and generates autonomously EOP1/EOP2 (as configured) markers afte r each end of a transmission packet. This mode also includes as a special submode: – Wormhole routing: This mode allows hardware routing of packets by the TSS901E.
• Simple Interprocessor Communication (SIC) Protocol Mode: This mode executes the simple interprocessor communication protocol as described in the protocol specification (1) . The following capabilities of the protocol are implemented into the TSS901E: – interpretation of the first 4 data tokens as the h eader bytes of the protocol – autonomous execution of the simple control command s as described in the protocol specification (1) – autonomous acknowledgement of received packets if configured In transmit direction no interpretation of the data is performed. This means that for transmit packets, the four header bytes must be generated by the host CPU and must be available as the first data read from the communication memory. EOP1/EOP2 control tokens are auto- matically inserted by the TSS901E when one configur ed transfer from the communication memory has finished. 1.

4167F–AERO–06/07 TSS901E TSS901E Control by Link A feature of the TSS901E is the possibility to control the TSS901E not only via HOCI but via one of the three links. This allows to use the TSS901E in systems without a local controller (µCon- troller, FPGA etc.). Since the HOCI is no longer us ed in this operation mode, it is instead available as a set of general purpose I/O (GPIO) lines. Wormhole Routing The TSS901E introduces a wormhole routing function similar to the routing implemented in the ST-Microelectronics C104 routing switch. Each of th e three links and the TSS901E itself can be assigned an eight bit address. When routing is enab led in the TSS901E, the first byte of a packet will be interpreted as the address destinati on byte, analysed and removed from the packet (header deletion). If this address matches o ne of the two other link addresses or the TSS901E address assigned previously, the packet wil l be automatically forwarded to this link or the FIFO of the TSS901E. If the header byte does no t match a link address, the packet will be written to the internal FIFO as well and an error interrupt (maskable) will be raised. PPU Functional

Description

Since the Protocol Processing Unit (PPU) determines a major part of the TSS901E functionality, the principal blocks of the PPU and their function are described here. This functionality is pro- vided for every DS link channel of the TSS901E.

• Protocol Execution Unit: This unit serves as the main controller of the PPU block. It receives the tokens from the DS macrocell and interprets (in protocol mode) the four header data characters received after an EOP1/EOP2 control character. If the address field matches the link channel address and the command field contains a valid command then forwarding of data into the receive FIFO is enabled. If the command field contains a "simple control command" then the execution request is forwarded to the command execution unit. The protocol execution unit also enables forwarding of header data characters to the acknowledge generator and provides an error signal in case of address mismatch, wrong commands or disabled safety critical "simple control commands". The protocol execution unit is disabled in "transpa rent" or “wormhole routing” operation mode.
• Receive, Transmit, Acknowledge: The transmit and receive FIFOs decouple the DS link related operations from the TSS901E related operations in all modes and such allows to keep the speed of the different units even when the source or sink of data is temporarily blocked. In the protocol mode a further FIFO (acknowledge FI FO) is used to decouple sending of acknowledges from receiving new data when the trans mit path is currently occupied by a running packet transmission.
• Command Execution Unit: This unit performs activating resp. deactivating of the CPU reset and the specific external signals and provides the capability to reset one or all links inside the TSS901E, all actions requested by the decoded commands from the protocol execution unit. The unit contains a register controlling the enable /disable state of safety critical commands which is set into the 'enable' state upon command r equest and which is reset after a safety critical command has been executed. The CPU reset and the specific external signals are forwarded to the Protocol Command Interface (PRCI).

4167F–AERO–06/07 TSS901E Fault Tolerance The IEEE Std 1355-1995 specifies low level checks a s link disconnect detection and parity check at token level. The TSS901E provides, through the Protocol Processing Unit, features to reset a link or all links inside the TSS901E, to re set the local CPU or to send special signals to the CPU commanded via the links. Additionally it is possible to enable a checksum co der/decoder to have fault detection capabili- ties at packet level. initial exploitation is for use in multi-processor systems where the standardisation or the high speed of the links is an important issue and where reliability is a requirement. Further application examples are heterogeneous systems or modules with out any communication features as spe- cial image compression chips, certain signal proces sors (TSC21020F, ERC32, ...), application specific programmable logic or mass memory. The TSS901E could also be used for single board sys tems where standardised high speed interfaces are needed. Even "non-intelligent" modul es such as A/D-converter or sensor inter- faces can be assembled with the TSS901E because of the "control by link" feature. The complete control of the TSS901E can be done via link from a central controller-node.

4167F–AERO–06/07 TSS901E Register Set This chapter describes the TSS901E registers which can be read or written by the HOCI or via the link (in case the "control by link" is enabled) to control TSS901E operations. All TSS901E control operations are performed by writes or reads of the respective registers. Most of the con- trol operations are obvious from the content of the registers. General Conventions:

• bit 0 (D0) = least significant bit,
• bit 7 (D7) = most significant bit (or bit 15 resp. bit 31)
• D x:0 means data bit x until bit 0. Access by HOCI: HOCI Data Transfer Big/Little endian selection of the HOCI is done using a special pin (HOSTBIGE) of the TSS901E. By connecting this pin to either Vcc or GND the HOC I is configured to be in little or big endian mode as follows: When Signal HOSTBIGE = '0' (GND), the HOCI data port is in little endian mode. When Signal HOSTBIGE = '1' (Vcc), the HOCI data port is in big endian mode. Little endian mode selected:
• 8 bit data port (default after reset) – register byte 0 is connected with pin HDATA0 - HDA TA7
• 16 bit data port – register byte 0 is connected with pin HDATA0 - HDA TA7 – register byte 1 is connected with pin HDATA8 - HDA TA15
• 32 bit data port – register byte 0 is connected with pin HDATA0 - HDA TA7 – register byte 1 is connected with pin HDATA8 - HDA TA15 – register byte 2 is connected with pin HDATA16 - HD ATA23 – register byte 3 is connected with pin HDATA24 - HD ATA31 Big endian mode selected:
• 8 bit data port (default after reset) – register byte 0 is connected with pin HDATA24 - HD ATA31
• 16 bit data port – register byte 0 is connected with pin HDATA24 - HD ATA31 – register byte 1 is connected with pin HDATA16 - HD ATA23
• 32 bit data port – register byte 0 is connected with pin HDATA24 - HD ATA31 – register byte 1 is connected with pin HDATA16 - HD ATA23 – register byte 2 is connected with pin HDATA8 - HDA TA15 – register byte 3 is connected with pin HDATA0 - HDA TA7 The registers of the TSS901E are 1, 2 or 4 Bytes wide. That means, if the HOCI data port is in 8 bit mode, 4 read or write accesses are necessary to access a 4 Byte register (e. g. the interrupt mask register). In 16/32 bit mode the data bits 31 - 8 are '0' if an 8 bit register is read.
