Hi all I have an optimized code running on DSK6416, as I count the number of instruction in my code , it is 74 and because the sampling rate is 8000Hz so it comes to .592 MIPS) I used the profiler and also TIMERs of DSP to measure the MIPS and it gives me almost a double(1.1 MIPS) number. I have checked my code to make sure, no part of it cause latency . I'm puzzled about the differ...

Hi to all, I am doing projects of AMR- WB(ITU G.722.2) & AMR- NB implementation on ARM9E. I have the following doubts, please clarify. 1) What are the standards for AMR- NB? Is 3gpp AMR-NB same as ITU G.723.1 ? 2) AMR- WB and GSM-AMR are same or not ? 2) What is the difference between ARM and TI- processors in the MIPS point of view ? 3) How many MIPS the AMR- WB will...

I'm interested in solving a sparse least-squares estimation problem on an embedded, MIPS processor. Is there any existing sparse linear algebra package for this platform? While MIPS does have floating-point capabilities, they are very limited, and I'd prefer a fixed point solution.

ok (Tim? :-), now I've got the PLL set to 150Mhz, all code and data located in internal RAM, I can verify actual 150 MIPS speed using RPT NOP instructions, but now when I time an actual C function such as the PID example TI supplies, it appears to be ~1/6 the speed of 150 MIPS. e.g. timing the following C function, I get about 5 us per call. Single stepping in assembler mode, I count about ...

Our school is selling these EZ-Kit Lites out for almost nothing. I'm wondering if it's possible to put two or more together so they become a parallel distributed computing system, as in, since they've 20 MIPS, can they become 20 MIPS x [number of 2181 together]? :) -- Mvh / Best regards, Jack, Copenhagen The email address is for real. :)

HEllo, I have an acquisition system of 30 measurements. The sampling rate for one acquisition is 1000 Hz. Each acquisition must be filtered with a FIR with 16 Taps and 16 sample of the signal acquistion will be used. I will use a TSM320C2xxx with a frequency of 150 Mhz. How many MIPs do i need to achieve thoses filtering operations. Thank oyu

## TI F2812 DSP actual MIPS < 150 ?

running a while() loop on the SpectrumDigital F2812 EZDSP evaluation board, using a 30 Mhz clock crystal, toggling the external XF bit after 10,000 while() loops, and monitoring timing on a scope, it appears that the 6 assembler instructions that comprise the while() loop are executed at a rate ~2.3MIPS. This seems a little low given the advertised 150 MIPS spec of the F2812. Am I thin...

Bonjour ? tous, Voil?, je recherche un DSP qui aurait les caract?ristiques suivantes : 60 MIPS min, 16 bits virgule fixe avec si possible flash ou EEPROM interne. Comme vous le voyez, ?a n'est pas hors du commun, 60 MIPS c'est m?me peu. Par contre, il serait utile d'avoir des entr?es sorties analogiques, du style : AD et DA 12 bits min. Les DSP ayant des AD sont trouvables, mais o? che...

Hello everyone, So I'm lookig for a DSP with the following characteristics : - about 80-100 MIPS - 16 bits fixed point operations - low-power for embedded application - on-chip flash (or EEPROM) - at least 8 12-bits A/D's As you see, my application doesn't require too much calculation power. But the problem is I just can't find what I need. All DSPs I find with all the peripherals are...

Hi all, I am trying to port AMR WB+ (fixed point Base line) to some platform. I want to calculte MIPS consumption of the codec. I know, if it takes 'X' million instructions per frame on the processor and 'T' is the frame duration, then MIPS = X/T I have the value of X with me. Can any body tell me the frame duration of AMR WB+ Codec (whether it is 20ms or something else). Thanks...

## C64 TI, Difference between running a code from external or L2 memory

Hi guys, I have a DSP code running on C64x and it is about 30 MIPS (the code resides in L2), if I use L2 for some other purposes and the DSP code resides in external memory (basically the Program should be transferred from External memory to cache whenever is needed), what is the effect of this change on the MIPS, is it going to be substantial or not. I appreciate any help or comments. ...
