The TMS320 family includes several generations of programmable processors with several devices in each generation. Since the programmable processors are split between fixed-point and floating-point devices both categories are examined in some detail. The TMS320C25 serves here as a simple example for the fixed-point processor family while the TMS320C30 is used for the floating-point family. Introduction Since its introduction in 1982 with the TMS32010 processor the TMS320 family of DSPs has been exceedingly popular. Different members of this family were introduced to address the existing needs for real-time processing but then designers capitalized on the features of the devices to create solutions and products in ways never imagined before. In turn these innovations fed the architectural and hardware configurations of newer generations of devices. Digital Signal Processing encompasses a
