DSP Simulator IIT Kharagpur • A DSP simulator simulates DSP environment on a computer like a PC without the actual DSP chip or hardware. • It can accept DSP assembly language programs. The assembly language programs developed using the assembly language tools can be executed using a simulator, off-line. • DSP based systems can be developed and tested using a simulator: • Low cost • Off-line testing Dept. of E & ECE © Prof. R. V. Raja Kumar

C Compiler IIT Kharagpur The C compiler converts a given program written in C language and produces the equivalent assembly language code.  No manual assembly language coding The so converted assembly code can be assembled, linked and used for implementing a system. Although, code generation can be done quickly, the code so generated is less efficient. Dept. of E & ECE © Prof. R. V. Raja Kumar

Assembly Language Tools IIT Kharagpur The assembly language tools create and use object files. The constituents are, Assembler:assembly lang. source files  m/c lang. obj. files (instructions, assembler and macro directives). Linker:Combines obj. files into single exe. Module. Archiver:Collects a group of files into a single archive file. Absolute lister:listing of absolute addresses of obj. file Cross-ref. Lister:shows symbols, their definitions and ref. In linked source files. Dept. of E & ECE © Prof. R. V. Raja Kumar
