The SMx320VC33 DSP is a 32-bit, floating-point processor manufactured in 0.18-µm four-level-metal CMOS (TImeline) technology. The SMx320VC33 is part of the SM320C3x™ generation of DSPs from Texas Instruments.

The SM320C3x internal busing and special digital-signal-processing instruction set have the speed and flexibility to execute up to 150 MFLOPS. The SMx320VC33 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 SMx320VC33 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. These features result in high performance and ease of use. 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 SM320C3x 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 SM/SMJ320VC33 is a superset of the TMS320C31. Designers now have an additional 1Mb 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 use the new features of the SM/SMJ320VC33 device. For general TMS320C3x architecture and programming information, see the TMS320C3x User’s Guide (SPRU031).

The SMx320VC33 device is packaged in 164-pin low-profile quad flatpacks (HFG suffix) and in 144-ball fine pitch ball grid arrays (GNL and GNM suffix).
