%T Porting the 3L Parallel C environment to the Texas Instruments TMS320C40 %A Alan D. Culloch %E Alastair R. Allen %B Proceedings of WoTUG\-15: Transputer Systems \- ongoing Research %X The TMS320C40 (\[rs]C40) is a transputer\-like parallel processor from Texas Instruments. It is an order of magnitude faster than the T800 transputer. Parallel C is a popular programming environment for the transputer. The properties of both the \[rs]C40 and Parallel C are described and the significant differences between the \[rs]C40 and the transputer are pointed out. The techniques used to overcome these obstacles to porting Parallel C are presented. These include building a new real\-time kernel and reusing existing software packages from industry and academia. The suitability of the \[rs]C40 for parallel applications is discussed.
