TECHNICAL SEMINAR BINAY KUMAR MISHRA 1 TMS320C6211 AND MICRO-50 EB DIGITAL SIGNAL PROCESSORS PRESENTED BY BINAY KUMAR MISHRA ROLL # EI UNDER THE GUIDANCE OF DR. SAROJ KUMAR MEHER

TECHNICAL SEMINAR BINAY KUMAR MISHRA 2 OUTLINE TMS320C6211 DIGITAL SIGNAL PROCESSOR MICRO-50 EB C-50 DEBUGGER CODE COMPOSER STUDIO V2

TECHNICAL SEMINAR BINAY KUMAR MISHRA 3 C6X SYSTEM BLOCK DIAGRAM ASIC with Programmable Digital Signal Core RAM ROM Standard Cells Codec Peripherals PERIPHERALSPERIPHERALSPERIPHERALSPERIPHERALS CPU Memory Internal Buses ExternalMemory

TECHNICAL SEMINAR BINAY KUMAR MISHRA 4 TMS320C6211 INSTRUCTION SET ARITHMETIC ADD ADDA SUB NEG MPY SUB SUBA LOGICAL AND NOT OR XOR COMPLT CLR SET

TECHNICAL SEMINAR BINAY KUMAR MISHRA 5 MICRO-50 EB DSP processor incorporated by Texas Instruments. Architecture similar to that of the C6x processors. No in-built memory. No external peripherals can be connected to provide external memory.

TECHNICAL SEMINAR BINAY KUMAR MISHRA 6 C-50 DEBUGGER Software used to program Micro-50 EB, when the kit is in serial mode. Supports ASM and ASC file format. The two modes in which Micro-50 EB works is Standalone Mode and Serial Mode.

TECHNICAL SEMINAR BINAY KUMAR MISHRA 7 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.

TECHNICAL SEMINAR BINAY KUMAR MISHRA 8 PROGRAM FLOW

TECHNICAL SEMINAR BINAY KUMAR MISHRA 9 CODE COMPOSER STUDIO V2 Software used to program the TMS320C6211 DSP Processor. Supports C, C++, Assembly Language concept of programming. The data stored in the processor is temporary and the software can be used again and again to re- program the processor.

TECHNICAL SEMINAR BINAY KUMAR MISHRA 10 PROGRAM FLOW

TECHNICAL SEMINAR BINAY KUMAR MISHRA 11 A PROBLEM AND ITS SOLUTION USING CCSV2 Let a problem be considered which involves both multiplication and addition and which is of the form: How the TIC6x is designed to handle this problem?

TECHNICAL SEMINAR BINAY KUMAR MISHRA 12 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.

TECHNICAL SEMINAR BINAY KUMAR MISHRA 13 DEVELOPING THE CODE MVK40, A2; A2 = 40, loop count MVK40, A2; A2 = 40, loop countloop: LDH*A5, A0; A0 = a(n) LDH*A5, A0; A0 = a(n) LDH*A6, A1; A1 = x(n) LDH*A6, A1; A1 = x(n) MPYA0, A1, A3; A3 = a(n) * x(n) MPYA0, A1, A3; A3 = a(n) * x(n) ADDA3, A4, A4; Y = Y + A3 ADDA3, A4, A4; Y = Y + A3 SUBA2, 1, A2; decrement loop count SUBA2, 1, A2; decrement loop count [A2] Bloop; if A2  0, branch STHA4, *A7; *A7 = Y STHA4, *A7; *A7 = Y

TECHNICAL SEMINAR BINAY KUMAR MISHRA 14 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.
