Programming a vector processor and parallel programming of an asymmetric dual multiprocessor comprised of a vector processor and a risc processor

摘要

The present invention provides a new programming language which. is a superset of C++ optimized for writing vectorized dual-threaded programs on the MSP media processor. This invention discloses novel language constructs in the syntax and semantics to facilitate efficient programming and the generation of optimized efficient MSP object code. We have invented in VIVID new data types such as VECTOR and GMASK as well as new operators that map directly into the MSP instruction set such as @shfl, @avg, etc. We have also extended C++ to facilitate dual-threaded execution by exposing the MSP's fork-join model to the VIVID programmer via. adding fork-join constructs to VIVID. We have also invented a syntax and semantics to facilitate having multiple returned results from a vector operation such as VD @@ VC=VA @shfl VB.
