4 Architectural Overview
The following sections describe the functionality and performance of the MC71000 Bluetooth Baseband Controller.
4.1 ARM7 Platform (A7P)
4.1.1 ARM7TDMI
The MC71000 Bluetooth Baseband Controller architecture is based around the 32-bit ARM7TDMI microprocessor. It is an industry-standard processor recognized for its efficient MIPS/WATT benchmark, along with excellent code efficiency when working in the 16-bit THUMB mode. The architecture is based on RISC principles and supports two instruction sets: The 32-bit ARM instruction set The 16-bit THUMB instruction set
4.2 Memory Sub-System
Program execution in the MC71000 Bluetooth Baseband Controller is predominantly ROM-based, with internal SRAM being used for code patching. An image can be uploaded from a host system, or a low-cost serial E2PROM (four-wire connection).
4.2.1 External Interface Module (EIM)
The external interface module (EIM) handles the interface to external devices, as well as generation of chip selects for external peripherals and memory. It contains a zero-glue interface to external memories (SRAM, E2PROM, and FLASH chips).
4.3 Peripherals Sub-System
4.3.1 Clock and Reset Module (CRM)
The clock and reset module (CRM) is dedicated to handling all clock, reset, and power management features in the MC71000 Bluetooth Baseband Controller. It assures that the different clock and reset signals are stable before they are fed to the internal logic in the MC71000 Bluetooth Baseband Controller.
MOTOROLA MC71000 Advance Information 5 Preliminary The CRM is designed to make full use of the facilities supplied by the Bluetooth standard to conserve power, while still maintaining a Bluetooth link. For this purpose, the CRM is connected to an on-chip low-power oscillator, which generates a frequency using an external low cost 32.768 kHz crystal. The CRM module also includes a watchdog to safeguard against any potential software failures.
4.3.2 Bluetooth Link Controller (BTLC)
The Bluetooth link controller module (BTLC) handles all link controller specific functions. Raw data can be read from/written to the module, and the BTLC takes care of transmission related timing, as well as data signal processing functions like encryption and cyclic redundancy check (CRC)/header error correction (HEC) generation. Embedded in the BTLC are also the dedicated Bluetooth timers, which maintain an accurate estimate of time in both the native and the remote module. A small and dedicated Bluetooth serial peripheral interface controller handles all serial communication with the MC13180 Bluetooth RF Integrated Circuit.
4.3.3 Bluetooth Audio Signal Processor (BTASP)
Special attention has been put on audio quality for the end user. For this purpose, a dedicated Bluetooth audio signal processing module (BTASP) has been designed to give users excellent and superior audio performance. With a minimum of processor intervention, this module handles all filtering, interpolation, as well as encoding/decoding (aLaw, uLaw, and CVSD).
4.3.4 High-Speed UART (up to 2 Mb/sec @ 24 MHz)
The Universal Asynchronous Receiver/Transmitter (UART) module provides one of the main interfaces to the MC71000 Bluetooth Baseband Controller. The generated baud rate is based upon a configurable divisor and input clock. It can be configured to send one or two stop bits as well as odd, even, or no parity. The UART transmit and receive buffer sizes are 32 bytes each.
4.3.5 Dual High-speed CSPI (up to 2 Mb/sec @ 24 MHz)
The MC71000 Bluetooth Baseband Controller contains two configurable serial peripheral interface (CSPI) modules, CSPI0 and CSPI1. CSPI0 can connect to a variety of SEEPROM and serial flash devices. Both CSPI modules are master/slave configurable, equipped with 16 byte data out buffers (transmit and receive FIFOs), and allow the MC71000 Bluetooth Baseband Controller to interface with external CSPI master or slave devices. Incorporating the SPIRDY and SS control signals, it enables fast data communication with a fewer number of software interrupts.
4.3.6 High-Speed SSI (up to 2 Mb/sec @ 24 MHz)
The synchronous serial interface module (SSI) is a full-duplex serial port allowing digital signal processors (DSPs) to communicate with a variety of serial devices, including industry-standard CODECs, other DSPs, microprocessors, and peripherals. The SSI is typically used to transfer samples in a periodic manner and consists of a variety of registers that handle port, status, control, transmit and receive, serial clock generation, and frame synchronization.
