This paper presents the MIPS32 DSP ASE (applications-specific extension) and provides performance optimisation hints and example code.

MIPS' MIPS32 24KE and 34K core families, collectively called 24KE throughout this document, implements the MIPS DSP ASE (Digital Signal Processing Application Specific Extension). The DSP ASE enhances the MIPS32 and MIPS64 architectures with a set of new instructions and state that optimises the performance of signal processing and multimedia applications. The performance of tasks such as audio encoding and decoding, image and video processing, and speech communication is improved by the use of the DSP ASE. The 24KE and the 34K core families implement the MIPS32 DSP ASE and therefore benefits the many signal processing application listed above.
