POSIX Threads for embedded systems (PTE)PTE is an open source implementation of the POSIX API for multithreaded applications (pthreads). It is intended to be used to provide a pthreads API for embedded operating systems that do not natively provide a pthreads API. PTE is designed to be easily portable to such operating systems and only relies on basic primitives (e.g. semaphores) that are widely supported on most embedded operating systems.Currently, PTE has been ported to Texas Instrument's DSP/BIOS and Sony's PSP OS.PTE is based heavily on Pthreads Win32, and implementation of pthreads for Windows. Information on building and porting PTE is available at https://github.com/jschmidlapp/pthreads-emb/wiki.
