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.

equal in size, or more memory can be allocated for Y-RAM in 2kword blocks.
The CS485xx family DSPs are single-core DSP with separate X and Y data and P code memory
The DSP core is coupled to a flexible DMA engine. The DMA engine can move data between
CS485xx family functionality is controlled by application codes that are stored in on-board ROM or
Users can develop their applications using DSP Composer to create the processing chain and then
The CS485xx is suitable for a variety of audio post-processing applications such as automotive
The DSP core has its own on-chip data and program RAM and ROM and does not require external
