32-bit Audio Decoder DSP Family ©Copyright 2006 Cirrus Logic, Inc. DS734A3 CONFIDENTIAL CONFIDENTIAL DRAFT DELPHI 2. Overview The CS48500 DSP Family is designed to provide high-performance post-processing and mixing of ditial audio. The dual clock domain provided on the PCM inputs allows for the mixing of audio streams with different sampling frequencies. The low-power standby preserves battery life for applications which are always on, but not necessarily processing audio, such as automotive audio systems. There are three devices comprising the CS48500 family. The CS48520, CS48540 and CS48560 are differentiated by the number of inputs and outputs available. All DSPs support dual input clock domains and dual audio processing paths. All DSPs are available in a 48-pin QFP package. Please refer to Table 2 on page 8 for the input, output, firmware features of each device.

2.1 Licensing

Licenses are required for all of the 3rd party audio processing algorithms listed in Section 3. Please contact your local Cirrus Logic Sales representative for more information.

32-bit Audio Decoder DSP Family DS734A3 ©Copyright 2006 Cirrus Logic, Inc. CONFIDENTIAL CONFIDENTIAL DRAFT DELPHI 3. Code Overlays The suite of software available for the CS48500 family consists of an operating system (OS) and a library of overlays. The overlays have been divided into three main groups called Matrix-processors, Virtualizer- processors, and Post-processors. All software components are defined below: 1. OS/Kernel - Encompasses all non-audio processing tasks, including loading data from external memory, processing host messages, calling audio-processing subroutines, error concealment, etc. 2. Matrix-processor- Any Module that performs a matrix decode on PCM data to produce more output channels than input channels (2Ön channels). Examples are Dolby ProLogic IIx and DTS Neo:6. Generally speaking, these modules increase the number of valid channels in the audio I/O buffer. 3. Virtualizer-processor - Any module that encodes PCM data into fewer output channels than input channels (nÖ2 channels) with the effect of providing “phantom” speakers to represent the physical audio channels that were eliminated. Examples are Dolby Headphone® and Dolby Virtual Speaker®. Generally speaking, these modules reduce the number of valid channels in the audio I/O buffer. 4. Post-processors - Any module that processes audio I/O buffer PCM data in-place after the matrix- or virtualizer-processors. Examples are bass management, audio manager, tone control, EQ, delay, customer-specific effects, etc. The bulk of each overlay is stored in ROM within the CS48500, but a small image is required to configure the overlays and boot the DSP. This small image can either be stored in an external serial FLASH/EEPROM, or downloaded via a host controller through the SPI™/I2C® serial port. The overlay structure reduces the time required to reconfigure the DSP when a processing change is requested. Each overlay can be reloaded independently without disturbing the other overlays. For example, when a new matrix-processor is selected, the OS, virtualizer-, and post-processors do not need to be reloaded — only the new matrix-processor (the same is true for the other overlays). Table 2 below lists the firmware available based on device selection. Please refer AN298, CS48500 Firmware User’s Manual for the latest listing of application codes and Cirrus Framework™ modules available.

32-bit Audio Decoder DSP Family DS734A3 ©Copyright 2006 Cirrus Logic, Inc. CONFIDENTIAL CONFIDENTIAL DRAFT DELPHI 4. Hardware Functional Description

4.1 DSP Core

The CS48500 is a single-core DSP with separate X and Y data and P code memory spaces. The DSP core is a high-performance, 32-bit, user-programmable, fixed-point DSP that is capable of performing two multiply-and-accumulate (MAC) operations per clock cycle. The DSP core has eight 72-bit accumulators, four X- and four Y-data registers, and 12 index registers. The DSP core is coupled to a flexible DMA engine. The DMA engine can move data between peripherals such as the serial control port (SCP), digital audio input (DAI) and digital audio output (DAO), or any DSP core memory, all without the intervention of the DSP. The DMA engine off loads data move instructions from the DSP core, leaving more MIPS available for signal processing instructions. CS48500 functionality is controlled by application codes that are stored in on-board ROM or downloaded to the CS48500 from a host controller or external serial FLASH/EEPROM. Users can develop their applications using DSP Composer to create the processing chain and then compile the image into a series of commands that are sent to the CS48500 through the SCP. The processing application can either load modules (matrix-processors, virtualizers, post-processors) from the DSPs on-board ROM, or custom firmware can be downloaded through the SCP. The CS48500 is suitable for a variety of audio post-processing applications such as automotive head- ends, automotive amplifiers, and boom boxes.

4.1.1 DSP Memory

The DSP core has its own on-chip data and program RAM and ROM and does not require external memory for post-processing applications. The Y-RAM and P-RAM share a single block of memory that can be configured to make Y and P equal in size, or more memory can be allocated for Y-RAM in 2kword blocks.

4.1.2 DMA Controller

The powerful 8-channel DMA controller can move data between 8 on-chip resources. Each resource has its own arbiter: X, Y, and P RAMs/ROMs and the peripheral bus. Modulo and linear addressing modes are supported, with flexible start address and increment controls. The service intervals for each DMA channel, as well as up to 6 interrupt events, are programmable.

32-bit Audio Decoder DSP Family ©Copyright 2006 Cirrus Logic, Inc. DS734A3 CONFIDENTIAL CONFIDENTIAL DRAFT DELPHI

4.2 On-chip DSP Peripherals

4.2.1 Digital Audio Input Port (DAI)

Each version of the CS48500 support a different number of input channels. Refer toTable 2 on page 8 for more details. The DAI port supports a wide variety of data input formats at sample rates (Fs) as high as 192 kHz. The port is capable of accepting PCM or DSD formats. Up to 32-bit word lengths are supported. DSD is supported and internally converted to PCM before processing. The DAI also supports a time division multiplexed (TDM) one-line data mode, that packs PCM audio on a single data line (the total number possible depends on the ratio of SCLK to LRCLK and the version of chip. For example on the CS48520 only 4 ch of PCM are supported in one line mode and on the CS48560 up to 8 channels are supported.). The port has two independent slave-only clock domains. Each data input can be independently assigned to a clock domain. The sample rate of the input clock domains can be determined automatically by the DSP, off-loading the task of monitoring the SPDIF receiver from the host. A time-stamping feature allows the input data to be sample-rate converted via software.

4.2.2 Digital Audio Output Port (DAO)

Each version of the CS48500 support a different number of output channels. Refer toTable 2 on page 8 for more details. DAO port supports PCM resolutions of up to 32-bits. The port supports sample rates (Fs) as high as 192 kHz. The port can be configured as an independent clock domain mastered by the DSP, or as a clock slave if an external MCLK or SCLK/LRCLK source is available. One of the serial audio pins can be re- configured as a SPDIF transmitter that drives a bi-phase encoded S/PDIF signal (data with embedded clock on a single line).

4.2.3 Serial Control Port (I2C® or SPI™)

The on-chip serial control port is capable of operating as master or slave in either SPI™ or I2C® modes. Master/Slave operation is chosen by mode select pins when the CS48500 comes out of reset. The serial clock pin can support frequencies as high as 25 MHz in SPI mode (SPI clock speed must always be ≤ (Fdclk/2)). The CS48500 serial control port also includes a pin for flow control of the communications interface (#SCP_BSY) and a pin to indicate when the DSP has a message for the host (#SCP_IRQ).

4.2.4 GPIO

Many of the CS48500 peripheral pins are multiplexed with GPIO. Each GPIO can be configured as an output, an input, or an input with interrupt. Each input-pin interrupt can be configured as rising edge, falling edge, active-low, or active-high.

4.2.5 PLL-based Clock Generator

The low-jitter PLL generates integer or fractional multiples of a reference frequency which are used to clock the DSP core and peripherals. Through a second PLL divider chain, a dependent clock domain can be output on the DAO port for driving audio converters. The CS48500 defaults to running from the external reference frequency and is switched to use the PLL output after overlays have been loaded and configured, either through master boot from an external FLASH or through host control. A built-in crystal oscillator circuit with a buffered output is provided. The buffered output frequency ratio is selectable between 1:1 (default) or 2:1.

32-bit Audio Decoder DSP Family DS734A3 ©Copyright 2006 Cirrus Logic, Inc. CONFIDENTIAL CONFIDENTIAL DRAFT DELPHI

4.2.6 Hardware Watchdog Timer

The CS48500 has an integrated watchdog timer that acts as a “health” monitor for the DSP. The watchdog timer must be reset by the DSP before the counter expires, or the entire chip is reset. This peripheral ensures that the CS48500 will reset itself in the event of a temporary system failure. In stand- present) a GPIO will be used to signal the host that the watchdog has expired and the DSP should be rebooted and re-configured.

4.3 DSP I/O Description

4.3.1 Multiplexed Pins

Many of the CS48500 pins are multi-functional. For details on pin functionality please refer to the CS48500 Hardware User’s Manual.

4.3.2 Termination Requirements

Open-drain pins on the CS48500 must be pulled high for proper operation. Please refer to the CS48500 Hardware User’s Manual to identify which pins are open-drain and what value of pull-up resistor is required for proper operation. Mode select pins on the CS48500 are used to select the boot mode upon the rising edge from reset. A detailed explanation of termination requirements for each communication mode select pin can be found in the CS48500 Hardware User’s Manual.

4.3.3 Pads

The CS48500 I/Os operate from the 3.3 V supply and are 5 V tolerant.

4.4 Application Code Security

The external program code may be encrypted by the programmer to protect any intellectual property it may contain. A secret, customer-specific key is used to encrypt the program code that is to be stored external to the device. Please contact your local Cirrus representative for details.
