A 350 MHz 5.6GOPS/1.4 GFLOPS 4-Way VLIW Embedded Microprocessor

摘要

A 5.6GOPS/1.4GFLOPS 350MHz, four-way very long instruction word (VLIW) microprocessor is developed for embedded applications in a 0.18μm five-layer-metal CMOS process. This processor features a two-way integer pipeline and two-way floating/media pipelines. Each floating pipeline and me- dia pipeline has two-parallel and four-parallel single instruction multiple-data (SIMD) mechanisms, respectively.
