105 / 110 page  DSP56366 Technical Data, Rev. 3.1 Freescale Semiconductor A-1 Appendix A Power Consumption Benchmark The following benchmark program permits evaluation of DSP power usage in a test situation. It enables the PLL, disables the external clock, and uses repeated multiply-accumulate instructions with a set of synthetic DSP application data to emulate intensive sustained DSP operation. ;********************************************************************;********* *********************************************************** ;* ;* CHECKS Typical Power Consumption ;******************************************************************** page 200,55,0,0,0 nolist I_VEC EQU $000000 ; Interrupt vectors for program debug only START EQU $8000 ; MAIN (external) program starting address INT_PROG EQU $100 ; INTERNAL program memory starting address INT_XDAT EQU $0 ; INTERNAL X-data memory starting address INT_YDAT EQU $0 ; INTERNAL Y-data memory starting address INCLUDE "ioequ.asm" INCLUDE "intequ.asm" list org P:START ; movep #$0123FF,x:M_BCR; BCR: Area 3 : 1 w.s (SRAM) ; Default: 1 w.s (SRAM) ; movep #$0d0000,x:M_PCTL ; XTAL disable ; PLL enable ; CLKOUT disable ; ; Load the program ; move #INT_PROG,r0 move #PROG_START,r1 do #(PROG_END-PROG_START),PLOAD_LOOP move p:(r1)+,x0 move x0,p:(r0)+ nop PLOAD_LOOP ; ; Load the X-data ; move #INT_XDAT,r0 |
