Hello C6x Pals I want know some basic tips for calculating the MIPS. Can any one suggest as how to calculate the MIPS for a code written in C. Will profiling help me ? Are MIPS the general indicators of an efficient code? For C6211 for instance,it reads as 1200 MIPS, but

## C6713 MIPS Measurement Issue

Hi C6x Group members, I'm trying testing the MIPS of C6713 on DSK6713. I have a simple loop-back program to get an audio sample from A/D then output to D/A. There is some delay between input and output so I can figure out the MIPS. Why can I only execute maximum 3000 times of (a+b) for this delay? So for 8kHz sampling rate, the MIPS is only 3000*8000=24MIPS. Anything wrong with my program? ...

Hi everybody, I have to calculate MIPS taken for my code. To calculate MIPS, I have a formula ==> MIPS = (Total num of cycles/Total num of Instructions)*CPU_Freq. If the formula is right, then, with the help of profiling in CCS, I can find the cycles taken, but what about the instructions, should I do manually?? Or, is there any way to find it out during profiling itself. Waiting for

Hi All, I have a query on representation of performance of DSP algorithms and its complexity. As far as I know, it has always been in terms of MIPS. Considering the advancements in the hardware, the architectures, the pipeline depths, the clocking speeds would it be appropriate to represent the same in terms of MHz (MCPS). The reason for phrasing this question is that, I notice quite a few p...

Hi; As you know MELPe receive 16-bit inputs and the processing includes some 8-bit operations. My question is that: "Would you know if a 16-bit addressable DSP,like c55x, is used to implement MELPe how much (in percent) of memory may be unused?" "In the above case is there any way to use dissipated memory without MIPs increasing?" I saw the price of 1MW 10ns asynchronous RAM from IS...
