TMS320C55x是德州仪器公司的新一代高性能低功耗定点数字信号处理器。以TMS320C5509为例介绍了TMS320C55x系列的特点和性能指标,并重点介绍了DMA技术在C5509中的使用,最后给出DMA的编程实例。该实例中控制寄存器的定义和引用可用于对其他片内外设的编程。
TMS320C55x is a new generation of Texas Instruments high-performance low-power fixed-point digital signal processor. Taking the TMS320C5509 as an example, this paper introduces the features and performance of the TMS320C55x series, and introduces the use of DMA technology in the C5509. Finally, the DMA programming examples are given. The definition and reference of control registers in this example can be used to program other on-chip peripherals.
