The TMS320C3x 32-bit floating-point DSP generation includes a variable-width external-memory interface, fast instruction cycle time, power-down modes, two-channel DMA coprocessor with configurable priorities, flexible boot loader, relocatable interrupt-vector table, and edge- or level-triggered interrupts.

The TMS320C4x DSPs are 32-bit, floating-point processors designed primarily for parallel processing that include six on-chip communication ports for processor-to-processor communication with no external-glue logic.
