Assembly programs with extension .asm and C programs with extension .c or .h have been compiled and tested with Texas Instru- ments' Code Composer Studio IDE C5000 version 1.2. Data files with extension .dat are used for C code, and the files with extension .inc are used for the C55x assembly programs. Chapter 1 exp1.c exp1.cmd Chapter 2 exp2a.c exp2b.c...

Some of the advantages of a DSP system over analog circuitry are summarized as follows:. The performance of the algorithms can be verified using a low-cost general-purpose computer such as a personal computer (PC).. Figure 1.1 Basic functional blocks of real-time DSP system. Each of the functional blocks in Figure 1.1 will be introduced in the subsequent sections. in Figure...

In this chapter, we will introduce the architecture and assembly programming of the Texas Instruments TMS320C55x fixed-point processor.. Each generation of the TMS320 series has a unique central processing unit (CPU) with a variety of memory and peripheral configurations. Some essential features of the C55x device are listed below:. The instruc- tion set of the C55x varies in length. Figure...

Therefore DSP implementation with fixed-point hardware requires special attention because of the potential quantization and arithmetic errors, as well as the possibility of overflow.. Section 3.3 introduces probability and random processes, which are useful in analyzing the finite- precision effects in the latter half of the chapter and adaptive filtering in Chapter 8. The analog sinewave can be expressed as....

Example 4.1: The waveform of a rectangular pulse train shown in Figure 4.1 is a periodic signal with period T 0 ,and can be expressed as. This plot is called the power density spectrum of the periodic signal x(t). This equation indicates that there is no power in any of the harmonic k 6 1.. The number of frequency components...
