Improve Your MIPS Development

Let our extensive experience with the MIPS family of microprocessors help your product development. ThreadX, our high-performance real-time kernel, helps improve your product's quality and its time-to-market. In addition, using ThreadX makes it easier to enhance your product in the future.

MIPS Optimizations

ThreadX optimizes context switching on the R3000. When context switching occurs inside of a ThreadX service call, only the registers preserved across function calls are saved as part of the thread's context, i.e. registers s0-s8.

A similar technique is used in interrupt handling. On the front end of interrupt service routines, only the compiler's scratch registers are saved initially (registers at, v0-v1, a0-a3, and t0-t9). The full register set is saved only if thread preemption is required.

Easy to Use

ThreadX is designed for ease of use. Our API is designed to be easy to understand, powerful, and consistent. The same is true with our reference manual and other supporting documentation.

Development Tool Choices

ThreadX is completely compatible with all the major MIPS development tools, including GNU, EPI, and the Green Hills MULTI tools. Additional ThreadX-aware debugging is available with MULTI from Green Hills.
