Code library moves cross-platform

摘要

The Parallel Vector Tile Optimizing Library (PVTOL), developed by MIT Lincoln Laboratory, Lexington, Mass., is a real-time, portable C code signal processing software library that facilitates cross-platform portability of programs without sacrificing performance.PVTOL allows signal processing algorithm code to be written at a high level, using task and data objects that may be parallel, but that insulate the application from details of how those objects are mapped to the parallel architecture or how they synchronize and communicate.The library's programs are scaled by changing maps of the distributed objects. Mapping is specified separately from the algorithm code, so the algorithm code does not need to be changed to take advantage of a larger or smaller number of processing elements.
