The TMS320C4x devices are 32-bit floating-point digital signal processors optimized for parallel processing. The 'C4x family combines a high-performance CPU and DMA controller with up to six communication ports to meet the needs of multiprocessor and I/O-intensive applications. All 'C4x devices are compatible with TI's multichip development environment. Each device contains an on-chip analysis module that supports hardware breakpoints for parallel-processing development and debugging. The 'C4x family accepts source code from the TMS320C3x family of floating-point DSPs. Key applications of the 'C4x family include three-dimensional graphics, image processing, networking, and telecommunications base stations.
