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.

General-purpose applications are greatly enhanced by the large address space, multiprocessor interface, internally and externally generated wait states, one external interface port, two timers, one serial port, and multiple-interrupt structure. The TMS320C3x supports a wide variety of system applications from host processor to dedicated coprocessor. High-level-language support is easily implemented through a register-based architecture, large address space, powerful addressing modes, flexible instruction set, and well-supported floating-point arithmetic.

The TMS320VC33 is a superset of the TMS320C31. Designers now have an additional 1M bits of on-chip SRAM, a maximum throughput of 150 MFLOPS, and several I/O enhancements that allow easy upgrades to current systems or creation of new baselines. This data sheet provides information required to fully utilize the new features of the TMS320VC33 device. For general TMS320C3x architecture and programming information, see the TMS320C3x User’s Guide (literature number SPRU031).
