MetaCore: A Con gurable & Instruction-Level Extensible DSP Core

| The design of application-speci c processor for DSP applications is not only driven by low-cost requirements, but also needs to ful ll constraints in terms of short development time. MetaCore, a con gurable and instruction-level extensible DSP core, can e ectively satisfy these requirements by providing a high degree of customization to the given application. In this paper, we present architectural concept of MetaCore and the MetaCore development platform. And we also present the rstgeneration MetaCore product version, MDSP16, which is a 16-by-16 xed-point DSP processor. MDSP16 was implemented using 0.6 m TLM CMOS technology and has 50 MIPS peak performance.
