To efficiently design and implement DSP systems we must have a solid knowledge of DSP algorithms as well as a basic concept of processor architecture. In this chapter we will introduce the architecture and assembly programming of the Texas Instruments TMS320C55x fixed-point processor. Introduction Wireless communications telecommunications medical and multimedia applications are developing rapidly. Increasingly traditional analog devices are being replaced with digital systems. The fast growth of DSP applications is not a surprise when considering the commercial advantages of DSP in terms of the potentially fast time to market flexibility for upgrades to new technologies and standards and low design cost offered by various DSP devices. The rising demand from the digital handheld devices in the consumer market to the digital networks and communication infrastructures coupled with the emerging internet applications are the driving forces for DSP applications. In 1982 Texas Instruments introduced its first general-purpose fixed-point DSP device the TMS32010 to the consumer market. Since then the TMS320 family has extended into two major classes the fixed-point and floating-point processors. The TMS320 fixed-point family consists of Clx C2x C5x C2xx C54x C55x C62x and C64x. The TMS320 floating-point
