TMS320VC33中文资料C30x 浮点 DSP数据手册TI规格书

描述 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.

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).

简介

TMS320VC33属于集成电路（IC）的DSP（数字信号处理器）。由TI制造生产的TMS320VC33DSP（数字信号处理器）数字信号处理器是类似于微处理器或微控制器的器件，但区别在于其内部架构经修改，适用于对连续数据流连续执行以乘法和加法运算为主的算法，而不是以条件逻辑或大量并发进程为主的算法。该器件通常用于诸如音频或视频信号处理等应用。
