The SMx320VC33 DSP is a 32-bit, floating-point processor manufactured in 0.18-µmfour-level-metal CMOS (TImeline) technology. The SMx320VC33 is part of theSM320C3x™ generation of DSPs from TexasInstruments.

The SM320C3x internal busing and special digital-signal-processing instruction set havethe speed and flexibility to execute up to 150 MFLOPS. The SMx320VC33 optimizes speed byimplementing functions in hardware that other processors implement through software or microcode.This hardware-intensive approach provides performance previously unavailable on a singlechip.

The SMx320VC33 can perform parallel multiply and ALU operations on integer orfloating-point data in a single cycle. Each processor also possesses a general-purpose registerfile, a program cache, dedicated ARAUs, internal dual-access memories, one DMA channel supportingconcurrent I/O, and a short machine-cycle time. These features result in high performance and easeof use. General-purpose applications are greatly enhanced by the large address space,multiprocessor interface, internally and externally generated wait states, one external interfaceport, two timers, one serial port, and multiple-interrupt structure.

The SM320C3x supports a wide variety of system applications from host processor todedicated coprocessor. High-level-language support is easily implemented through a register-basedarchitecture, large address space, powerful addressing modes, flexible instruction set, andwell-supported floating-point arithmetic.

The SM/SMJ320VC33 is a superset of the TMS320C31. Designers now have an additional 1Mbof on-chip SRAM, a maximum throughput of 150 MFLOPS, and several I/O enhancements that allow easyupgrades to current systems or creation of new baselines. This data sheet provides informationrequired to fully use the new features of the SM/SMJ320VC33 device. For general TMS320C3xarchitecture and programming information, see the TMS320C3x User’s Guide (SPRU031).

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