The TMS320VC5502PGF300™ CPU provides two multiply-accumulate units, each capable of performing 17-bit × 17-bit multiplication operations in a single cycle. The central 40-bit Arithmetic Logic Unit (ALU) is supported by additional 16-bit ALUs. The use of the ALU is controlled by the instruction set, providing the ability to optimize parallelism and power consumption. These resources are managed in the address units (AU) and data units (DU) of the C55x CPU.
The C55x DSP family supports a variable byte width instruction set for increased code density. The instruction unit (IU) executes 32-bit program extractions from internal or external memory and queues instructions for the program unit (PU). The program unit decodes instructions, directs tasks to AU and DU resources, and manages a fully protected pipeline. The predictive branching capability avoids pipeline refresh when executing conditional instructions.
