Application Specific Extension

Imagination’s MIPS16e ASE (Application Specific Extension) is an optional extension to both the MIPS32 and MIPS64 architectures.

The MIPS16e ASE enables embedded system designers to reduce costs by decreasing the size of memory required to run their application by up to 40 percent compared to traditional 32-bit software implementations. In addition to providing advanced code density, the MIPS16e ASE also achieves a high level of power efficiency, and performance equivalent to that of 32-bit only implementations. The MIPS16e ASE also improves instruction cache hit rate. It is supported by hardware and software development tools from MIPS Technologies and other providers.
