Despite the current industry slowdown, many companies are continuing to produce new architectures for DSP applications. At the upcoming Microprocessor Forum, two startups and one established player— Siroyan, 3DSP, and LSI Logic, respectively—will disclose next generation high performance licensable DSP core architectures.
Siroyan will unveil the SRA328—an architecture that uses VLIW techniques and integrates DSP, RISC, and MMU technology. The SRA328 can have up to 32 separate execution units—an impressive level of parallelism. 3DSP will reveal its SP-20 "UniPHY" processor core. This superscalar architecture targets broadband applications using a SIMD approach and RISC-like features. LSI Logic will disclose the ZSP600, its second-generation superscalar DSP core based on the ZSP architecture.
Another very interesting architecture that will be disclosed at MPF is Broadcom's "Spice Engine" vector signal processor, which targets networking and communications applications.
