Texas Instruments TMS320C5515 Fixed-Point Digital Signal Processors

Texas Instruments TMS320C5515 Fixed-Point Digital Signal Processors feature a TMS320C5000™ core that achieves low power and high performance through increased parallelism and total focus on power savings. TI TMS320C5515 DSPs support 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. 

TI TMS320C5515 DSPs include a 10-bit SAR ADC and GPIO functions, providing sufficient pins for status, interrupts, and bit I/O for LCD displays, keyboards, and media interfaces. The peripheral set of these TI DSPs includes an external memory interface (EMIF) that provides glueless access to asynchronous memories and high-speed, high-density memories. TMS320C5515 DSPs are designed for use in a variety of low-power applications, including wireless audio devices, echo cancellation headphones, portable medical devices, and voice applications.
