SM320VC33PGEA120EP

数字信号处理器 DIGITAL SIGNAL PROCESSOR

The SM320VC33-EP DSP is a 32-bit, floating-point processor manufactured in 0.18-µm four-level-metal CMOS meline technology. The SM320VC33-EP 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 million floating-point operations per second MFLOPS. The SM320VC33-EP 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 SM320VC33-EP 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 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.
