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

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, I need to calculate the MIPS taken for a given C code. I have the formula for calculating Mips i.e., MIPS = (avg cycles per instruction)* processor frequency. but how to calculate the cycles and instruction for the C code. Now i am using Linux for C coding, also i am not using the TI processor, i am using PowerPC, so can anybody give me your ideas for doing this. Also can u send m...

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, In the G.726 standard fmult function is taking around 24 percent mips and in this multiplication is done in floating point format. how can it be done in more effective way to achieve the efficient mips on C64x simulator. If anyone has done this before he can help me. Regards, Mayank __________________________________________

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 everyone, When I profile the same code in simulator(6416 Functional Simulator) and DSK (TMS320c6416), the difference in MIPS(Million Instructions Per Cycle) between the two is 1.0.Hardware board is consuming more cycles (higher MIPS) than the simulator. What could be the reason?? Swaminathan.S India. ______________________________________________________________________

Has anyone here ever done a midi I/O on a C67x processor? As far as I know, there are two options, the first is to use the McBSP in Software UART mode (using up mips...) Or, to connect some kind of UART chip. Does anyone have any details of this?

Hi all, Can anyone tell me what are the performance figures of running of MPEG-4 simple profile on DM642/DM641 EVM board. Performance figure in terms of frame/s at specified bit rate and size and cpu load and MIPS taken.

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...

Hi, I finally got the ?DSP_fft16x16t? DSPLIB function working on the 6455, without much struggle. But, Initially I stumbled across an issue; ?DSP_fft16x16t? disables the GIE in CSR. I added code to turn it back on after the control returns from ?DSP_fft16x16t?. Questions: 1. Is this the expected behavior? I have read some threads mentioning this? I come from ARM/MIPS world, so in my o...
