Download free C-Language Programming for DSP.pdf rogramming in C for digital signal processing applications has moved into widespread use and many owerful tools have been developed to assist the programmer. By first understanding some of the basic concepts and special considerations involved, the experience can be extremely rewarding.

As the software tools strive to keep pace with the rapid development of powerful new DSP devices, the mastery of special programming skills will continue to be an exciting and dynamic process.

The C programming language has become the language of choice for many engineering applications, especially digital signal processing. The C language is extremely portable, compact, and lends itself well to structured programming techniques. It has been ported to virtually every major programming platform and is the predominant system programming language for the major operating systems used today.

Programmers familiar with the C language on PC or UNIX platforms should be aware of some key differences between C programming for general-purpose workstations and C programming for DSPs. Areas of attention include differences between native and cross compilers, simulators, I/O library support, run-time libraries, linkers, and memory modules.

The major difference in C compilers for DSP, as compared to typical C compilers found in most workstations, is that the object code produced does not execute on the host CPU, but rather on the DSP chip in the target board. This type of C compiler is called a cross compiler. The more conventional C compiler which produces code for the host CPU is known as a native compiler.

The reason that cross compilers are so much more appropriate than native compilers for DSP is that virtually no DSP processor environment can come close to providing all of the supporting I/O resources available on even the most modest workstation. Since the DSP code produced by the cross compiler cannot execute on the host CPU, there are two methods of testing and developing DSP code.
