Designed for low power consumption, the CSX700 combines aggressive clock gating techniques, custom silicon design with a low operating frequency. Simple clock management enables maximum application performance within defined power and thermal envelopes.
The MTAP processor is a massively data parallel architecture with a high degree of replication for efficiency and reliability. Performance is achieved from the high level of internal parallelism. The architecture is suited to sophisticated signal and image processing in the time and frequency domains.
The CSX700 is supported by a professional software development kit based around an optimizing ANSI C compiler. This includes fully featured debug and profiling tools. In addition to the standard C libraries, a suite of optimized libraries that provide common functionality such as FFT, BLAS and LAPACK functions are available.
Manufactured by IBM, in the USA, the CSX700 is in production and available now for new designs.
