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 ThreadXmakes 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 functioncalls 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 othersupporting documentation.
