The MIPS32 24KE core family: high-performance RISC cores with DSP enhancements

Keywords:MIPS32 24KE family? RISC core? DSP? application note?

The MIPS32 24KE core family is the latest high-performance synthesizable microprocessor cores from MIPS Technologies Inc. and features DSP enhancements at a negligible cost. The 24KE core family fills an important gap in the convergence of RISC processors and DSPs. This convergence is enabled by emerging market trends, and comes with cost advantages and technical challenges. The 24KE design meets these challenges quite handily as shown in this paper. The 24KE cores were built by adding the new DSP enhancements to the existing pipeline in the 24K cores. The performance benefit for DSP applications from these enhancements can be as much as two times compared to a 24K design. And yet the 24KEc core has minimal frequency degradation and increase in the die area compared to the 24Kc core.

This paper discusses some of the novel implementation techniques used to achieve this result.
