Application note contains an Application Programming Interface (API) used to control the Dolby Volume firmware. Includes detailed configuration and usage information for the GUI development tool.
CS4953xx Hardware User's Manual
AN288PPH, "Dolby(R) Volume Module" DSP ComposerTM User's Manual
The scope of the CS49DV8C Data Sheet is primarily the hardware specifications of the CS49DV8C devices. This includes hardware functionality, characteristic data, pinout, and packaging information. The intended audience for the CS49DV8C Data Sheet is the system PCB designer, MCU programmer, and the quality control engineer.
2. Overview
The CS49DV8C DSP is designed to provide high-performance volume control using the Dolby Volume algorithm. The CS49DV8, supports up to 7.1 Channels of Dolby Volume processing at 48 kHz, 44.1 kHz or 32 kHz while leaving the 2nd core of the DSP completely available for even further processing functions such as Quadruple Crossover Bass Management, Tone Control, and Multiband Parametric EQ. The CS49DV8C DSP, together with Cirrus Logic's comprehensive library of audio processing algorithms, enables the development of next-generation high-definition audio solutions. Cirrus Logic also provides a broad array of digital interface products, and audio converters, to meet your audio system-level design requirements. The CS49DV8C is available in a 128-pin LQFP package. Please refer to Table 2 on page 6 for the processor speed and available firmware for the CS49DV8C product family.

2.1 Licensing
Licenses are required for Dolby Volume and for all of the third party audio processing algorithms. Please contact your local Cirrus Sales representative for more information.
3. Firmware Supported
The suite of software available for the CS49DV8C family consists of operating systems (OS) and a library of overlays. The overlays have been divided into three main groups called Decoders, Midprocessors, and Post-processors. All software components are defined as follows: * OS/Kernel - Encompasses all non-audio processing tasks, including loading data from external memory, processing host messages, calling audio-processing subroutines, auto-detection, error concealment, etc. * Dolby Volume - The CS49DV8C can run Dolby Volume on either DSP A or DSP B. On the DSP that is not running Dolby Volume, it can run the firmware currently available on the CS4953xx family for that DSP (A or B).
4. Hardware Functional Description
4.1 DSP Core
The CS49DV8C is a dual-core DSP with separate X and Y data and P code memory spaces. Each core is a high-performance, 32-bit, user-programmable, fixed-point DSP that is capable of performing two memory access control (MAC) operations per clock cycle. Each core has eight 72-bit accumulators, four X- and four Y-data registers, and 12 index registers. Both DSP cores are coupled to a flexible DMA engine. The DMA engine can move data between peripherals such as the digital audio input (DAI) and digital audio output (DAO), external memory, or any DSP core memory, all without the intervention of the DSP. The DMA engine offloads data move instructions from the DSP core, leaving more MIPS available for signal processing instructions. CS49DV8C functionality is controlled by application codes that are stored in on-board ROM or downloaded to the CS49DV8C from a host MCU or external FLASH/EEPROM. Users can choose to use standard audio post-processor modules which are available from Cirrus Logic. 4.1.1 DSP Memory The memory maps for the DSPs are as follows. All memory sizes are composed of 32-bit words.
Table 3. CS49DV8C DSP Memory Sizes
Memory Type X Y P DSP A 16k SRAM, 32k ROM 24k SRAM, 32k ROM 8k SRAM, 32k ROM DSP B 10k SRAM, 8k ROM 16k SRAM, 16k ROM 8k SRAM, 24k ROM
4.1.2 DMA Controller The powerful 12-channel DMA controller can move data between 8 on-chip resources. Each resource has its own arbiter: X, Y, and P RAM/ROMs on DSP A; X, Y, and P RAM/ROMs on DSP B; external

CS49DV8C Data Sheet 32-bit Audio DSP Family
memory; and the peripheral bus. Modulo and linear addressing modes are supported, with flexible start address and increment controls. The service interval for each DMA channel as well as up to 6 interrupt events, is programmable.
4.2 On-chip DSP Peripherals
4.2.1 Digital Audio Input Port (DAI) The 12-channel (6 line) DAI port supports a wide variety of data input formats. The port is capable of accepting PCM or IEC61937. Up to 32-bit word lengths are supported. Additionally support is provided for audio data input to the DSP via the DAI from an HDMI receiver. 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, which off-loads 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) There are two DAO ports. Each port can output 8 channels of up to 32-bit PCM data. The port supports data rates from 32 kHz to 192 kHz. Each port can be configured as an independent clock domain in slave mode, or the ratio of the two clocks can be set to even multiples of each other in master mode. The two ports can also be ganged together into a single clock domain. Each port has one serial audio pin that can be configured as a 192 kHz SPDIF transmitter (data with embedded clock on a single line). 4.2.3 Serial Control Port 1 & 2 (I2C(R) or SPITM) There are two on-chip serial control ports that are capable of operating as master or slave in either I2C or SPI modes. SCP1 defaults to slave operation. It is dedicated for external host-control and supports an external clock up to 25MHz in SPI mode. This high clock speed enables very fast code download, control or data delivery. SCP2 defaults to master mode and is dedicated for booting from external serial Flash memory or for audio sub-system control. 4.2.4 External Memory Interface The external memory interface controller supports up to 128 Mbits of SDRAM, using a 16-bit data bus. 4.2.5 GPIO Many of the CS49DV8C 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. 4.2.6 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 CS49DV8C defaults to running from the external reference frequency and can be 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.

4.3 DSP I/O Description
4.3.1 Multiplexed Pins Many of the CS49DV8C pins are multi-functional. For details on pin functionality please refer to the CS4953xx Hardware User's Manual. 4.3.2 Termination Requirements Open-drain pins on the CS49DV8C must be pulled high for proper operation. Please refer to the CS4953xx 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 CS49DV8C are used to select the boot mode upon the rising edge of reset. A detailed explanation of termination requirements for each communication mode select pin can be found in the CS4953xx Hardware User's Manual. 4.3.3 Pads The CS49DV8C I/O operates from the 3.3 V supply and is 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.

1.Master mode timing specifications are characterized, not production tested. 2.Master mode is defined as the CS49DVxx driving both DAO_SCLK, DAO_LRCLK. When MCLK is an input, it is divided to produce DAO_SCLK, DAO_LRCLK. 3.This timing parameter is defined from the non-active edge of DAO_SCLK. The active edge of DAO_SCLK is the point at which the data is valid. 4.Slave mode is defined as DAO_SCLK, DAO_LRCLK driven by an external source.
