PROGRAM FLOW C-50 debugger only supports assembly level language programming. The biggest demerit of this software is that it is not code compatible with other middle level languages like “C”. This software is analogous to the PSPICE software which can give only the functional simulation but not the timing simulation. BINAY KUMAR MISHRA

CONCEPT BEHIND DEVELOPING THE CODE FOR CCSV2  The concept of pointers is used to develop the code.  An & operator is used to create a pointer to the values.  An * operator is used to load/store the values using the LDH and STH commands. BINAY KUMAR MISHRA

DEVELOPING THE CODE MVK 40, A2 ; A2 = 40, loop count loop: LDH LDH MPY ADD SUB [A2] B STH

*A5, A0 ; A0 = a(n) *A6, A1 ; A1 = x(n) A0, A1, A3 ; A3 = a(n) * x(n) A3, A4, A4 ; Y = Y + A3 A2, 1, A2 ; decrement loop count loop ; if A2 ≠ 0, branch A4, *A7 ; *A7 = Y

CONCLUSION  This software tool is not only compatible to design and simulate TMS320C6211 but also other VLIW machines with minor changes in the infrastructure.  This tool shall make design and simulation of future mobile devices easier and usher in a new era of design and simulation.
