TMS320C5505定点数字信号处理器 TMS320C5505 Fixed-Point Digital Signal Processor

Description

The TMS320C5505 is a member of "s TMS320C5000™ fixed-point Digital Signal Processor DSP product family and is designed for low-power applications. The TMS320C5505 fixed-point DSP is based on the TMS320C55x™ DSP generation CPU processor core. The C55x™ DSP architecture achieves high performance and low power through increased parallelism and total focus on power savings. The CPU supports an internal bus structure that is composed of one program bus, one 32-bit data read bus and two 16-bit data read buses, two 16-bit data write buses, and additional buses dedicated to peripheral and DMA activity. These buses provide the ability to perform up to four 16-bit data reads and two 16-bit data writes in a single cycle. The TMS320C5505 also includes four DMA controllers, each with 4 channels, providing data movements for 16-independent channel contexts without CPU intervention. Each DMA controller can perform one 32-bit data transfer per cycle, in parallel and independent of the CPU activity.
