TMS320VC5509 Fixed-Point Digital Signal Processor

Texas Instruments TMS320VC5509 Fixed-Point Digital Signal Processor (DSP) is based on the TMS320C55x DSP generation CPU processor core. The Texas Instruments TMS320C55x DSP architecture achieves high performance and low power through increased parallelism and total focus on reduction in power dissipation. The CPU supports an internal bus structure composed of one program bus, three data read buses, two data write buses, and additional buses dedicated to peripheral and DMA activity. These buses provide the ability to perform up to three data reads and two data writes in a single cycle. In parallel, the DMA controller can perform up to two data transfers per cycle independent of the CPU activity.
