The TMS320C3x's internal busing and special digital-signal-processing instruction set have the speed and flexibility to execute up to 150 million floating-point operations per second (MFLOPS). The TMS320VC33 optimizes speed by implementing functions in hardware that other processors implement through software or microcode. This hardware-intensive approach provides performance previously unavailable on a single chip. The TMS320VC33 can perform parallel multiply and ALU operations on integer or floating-point data in a single cycle. Each processor also possesses a general-purpose register file, a program cache, dedicated ARAUs, internal dual-access memories, one DMA channel supporting concurrent I/ O, and a short machine-cycle time. High performance and ease of use are the results of these features.
