Improve Your 386 32-bit Development

Let our extensive experience with the Intel 386 family of 32-bit 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.

386 32-bit Optimizations

ThreadX optimizes context switching on the 386. 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. This typically includes registers EBX, ESI, EDI, and EBP.

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 (typically EAX, ECX, and EDX). 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 386, 486 and Pentium development tools including Microsoft, MetaWare, Watcom, Borland, and the Green Hills MULTI development tools. Additional ThreadX-aware debugging is available with MULTI from Green Hills.
