4.1 Cirrus Logic 32-bit DSP Core
The CS470xx comes with a Cirrus Logic 32-bit core 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-data and four Y-data registers, and 12 index
registers.
The DSP core is coupled to a flexible 8-channel 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), sample rate converters (SRC), analog-to-digital converters (ADC), digital-to-analog
converters (DAC), 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.
CS470xx functionality is controlled by application codes that are stored in on-chip ROM or
downloaded to the CS470xx from a host controller or external serial FLASH/EEPROM.
Users can develop their applications using DSP ComposerTM to create the processing chain and
then compile the image into a series of commands that are sent to the CS470xx through the SCP.
The processing application can either load modules (post-processors) from the DSP’s on-chip
ROM, or custom firmware can be downloaded through the SCP.
The CS470xx is suitable for a variety of audio post-processing applications where sound quality via
sound enhancement and speaker/cabinet tuning is required to achieve the sound quality
consumers expect. Examples of such applications include automotive head-ends, automotive
amplifiers, docking stations, sound bars, subwoofers, and boom boxes.
4.2 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 includes three 2K word blocks (32
bits/word) that are assignable to either Y-RAM or P-RAM as shown in Table 4.
4.2.1 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.
