description
The TMS320VC33 DSP is a 32-bit, floating-point processor manufactured in 0.18-µm four-level-metal CMOS
(TImeline) technology. The TMS320VC33 is part of the TMS320C3x generation of DSPs from Texas
Instruments.
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.
