Searching SBC/DSP board/microcontroller; 4ADC/1kHz/USB Host
Hello, I am looking for something along the lines of a Single Board Computer (SBC), a Digital Signal Processing (DSP) board, or a microcontroller. Though I am open to any other suggestions, but what I essentially need to be able to do is the following. Requirements: - 4 channel ADC - Sample rate of 1kHz; meaning I want to be able to sample from all 4 channels at a rate of 1kHz, whether that means sampling each input individually (in a round-like fashion at a higher rate in order to complete sampling all 4 channels at an overall rate of 1kHz), or sampling all 4 channels at the same time each at a rate of 1kHz. - Can write to USB (USB Host port) Project Breakdown: I have 4 analogue signals I need converted to digital signals, and store on a USB key, at a rate of 1kHz. I am very new to working with these pieces of equipment, so please be understanding if I make any errors in talking about them, or am completely mistaken about the components to use. I have so far been steered in the direction of using a SBC or a DSP board. However, I’ve been searching for days going over board after board, and I can’t find anything that has a high enough sample rate. The closest I’ve found to what I need is a series of ARM single board computers, the TS-7000 series. http://www.embeddedarm.com/products/arm-sbc.php#ts-7800-series Other than the TS-7800, the others didn’t seem to come close enough.

DSP using a non DSP processor
My requirement is to use a moderate controller (Non DSP) and take analog sinusoidal signals (half second cycle 50 hz) , take their samples, do a Fourier transform to remove harmonics and then multiply them to find instantaneous power.

DSP@
DSP@ fetches the address of the top of stack, and places it on the stack. In doing so, of course, a new stack entry has to be created. So, which address goes on the stack? The previous one (before the new stack entry) or the new one? Currently, my code uses the new address: INCT R4 - create new stack entry MOV R4,*R4 - place address of stack pointer in top stack entry Mark.

If you have a machine with no native PUSH and POP, you can choose either of them. Strange to see a stack growing upwards, do you use a TI 99 or something? FIGFORTH for the 1802 had the data stack growing upwards and the return stack downwards. If the sequence 'DSP@ DSP!' does not change DEPTH, you're ok. On an Intel/AMD/Cyrix etc. PC you can do 'PUSH SP' followed by 'POP SP' and the stack pointer will not change, providing you do this on a 286 (just checked;-) or higher. -- Coos CHForth, 16 bit DOS applications http://home.hccnet.nl/j.j.haak/forth.html MarkWills <mar...

Help on DSP boards.
Hi, I am a CS student and an absolute newbie to the world of DSPs. I need to evaluate DSP boards that I can use to do some computation intensive operations in C programming. For example Kloosterman's sum K(a,b;p)=\sum e_p(ax+bx^*) , where ep(t) = e2pit / p and x* is the inverse of x modulo p and p is a prime number. I was wondering which DSP board I can use. I would want something that: 1. Be connected through USB/JTAG. 2. Can be programmed in C and has a good cross compiler, debugger and environment so that my environment is easy to use. Ideally, I would be doing this on 2-3 boards and come up with a performance analysis. Any help is appreciated. Thanks, Krushna I suggest you investigate using a PC with fast Pentium processor first especially when used in conjunction with Intel's Performance Primative library. At work, we have ceased using dedicated DSP boards, and now build ou systems based solely on Pentium CPUs. Our applications include HF Passiv Sonar, which is very demanding of processing power to run in real-time You can save megabucks taking this approach. Jeff Hi Jeff, This is more of an experiment than practical application. What we want for our performance analysis are results of the computation on say a fast Pentium processor and two-three DSP boards so that we know how useful it is to do such a thing. Since we are going to buy just a single DSP toolkit or two, cost should not be a consideration. The funding for that too is expect...

Hello, Sorry for my english, i'm french... I am newbie with the programming of DSP. I am in the search of an DSP evaluation board which also proposes a ADC and be programmable with a C environnement. The main use of this DSP board will be training and FFT calculation by sampling 10.7 Mhz IF frequency of an HF receiver. At this moment I didn't find an evaluation board with enough powerful ADC.

hi all, I am a postgraduate researcher based in Ireland. I am currently trying to use Matlab code developed by another researcher on a TMS320C6416 EVM.

The code will compile fine in CCS but I am unable to build it.

A fixed-point DSP does only fixed-point arithmetic, and usually has hardware to facilitate multiplication. A floating-point DSP has extra hardware for floating-point addition and multiplication (addition is a bit more involved than multiplication) and often omits the hardware to facilitate fixed-poing multiplication. Expect some difference in the size of a few registers. A matter of curiosity (mine): What difference had you imagined?

i'm using xmms... and after doing a cvsup/rebuild from (8.0-release) to: FreeBSD elhdt.hoe 8.1-PRERELEASE FreeBSD 8.1-PRERELEASE #3: Sat Jun 12 15:39:04 PDT 2010 root@elhdt:/usr/obj/usr/src/sys/GENERIC i386 xmms nolonger works... and i think that problem is that 8.1-pre- release can now see additional sound devices that weren't seen before... my problem, is how do i get xmms working again (i think, rebind the /dev/dsp device?) how to bind /dev/dsp to a different beast.... elhdt# ls -l /dev/dsp crw-rw-rw- 1 root wheel 0, 117 Jun 18 13:07 /dev/dsp elhdt# ls -l /dev/dsp* crw-rw-rw- 1 root wheel 0, 111 Jun 17 15:41 /dev/dsp0.0 crw-rw-rw- 1 root wheel 0, 117 Jun 18 13:07 /dev/dsp0.1 crw-rw-rw- 1 root wheel 0, 90 Jun 17 15:41 /dev/dsp1.0 crw-rw-rw- 1 root wheel 0, 89 Jun 17 15:41 /dev/dsp2.0 crw-rw-rw- 1 root wheel 0, 88 Jun 17 15:41 /dev/dsp3.0 crw-rw-rw- 1 root wheel 0, 87 Jun 17 15:41 /dev/dsp4.0 hmm... clearly, devfs is synthesizing the response to the stat for /dev/dsp by the first ls -l, and the second shows that /dev/dsp is not really there, (the shell expansion of '*' doesn't see it) - so /dev/dsp is probably some sort of artificial virtual object synthesized by devfs. my problem is this. i want to bind to the dsp3.0 (pcm3) equivalent device, and not the pcm equivalent device (i think). how can i do this ? any help or suggestions would be appreciated! elh...

DSP@
DSP@ fetches the address of the top of stack, and places it on the stack. In doing so, of course, a new stack entry has to be created. So, which address goes on the stack? The previous one (before the new stack entry) or the new one? Currently, my code uses the new address: INCT R4 - create new stack entry MOV R4,*R4 - place address of stack pointer in top stack entry Mark.

If you have a machine with no native PUSH and POP, you can choose either of them. Strange to see a stack growing upwards, do you use a TI 99 or something? FIGFORTH for the 1802 had the data stack growing upwards and the return stack downwards. If the sequence 'DSP@ DSP!' does not change DEPTH, you're ok. On an Intel/AMD/Cyrix etc. PC you can do 'PUSH SP' followed by 'POP SP' and the stack pointer will not change, providing you do this on a 286 (just checked;-) or higher. -- Coos CHForth, 16 bit DOS applications http://home.hccnet.nl/j.j.haak/forth.html MarkWills <mar...
DSP experiment board
Hello Comp.DSP! I have recently made first contact with the DSP-world in a undergraduate course where I have been using a Texas Instruments C6711 DS Starter Kit. I would like to get suggestions on other DSP-boards with integrate AD/DA:s for audio applications that I might buy and continue experimentin with at home. (It doesn't need to be Texas Instruments) Are there any good alternatives out there? Thanks in advance, Viktor On May 26, 9:16 am, "luminous" <vikt...@mail.nu> wrote: > Hello Comp.DSP!

TI also sells a TMS320C6416 DSP starter kit for about US $500. The 6713 is the floating point version and the 6416 is the fixed point version. If you get either of these kits I also suggest you get the second edition of the book "Digital Signal Processing and Applications with the TMS320C6713 and MS320C6416.

Help on DSP boards.
Hi, I am a CS student and an absolute newbie to the world of DSPs. I need to evaluate DSP boards that I can use to do some computation intensive operations in C programming. For example Kloosterman's sum K(a,b;p)=\sum e_p(ax+bx^*) , where ep(t) = e2pit / p and x* is the inverse of x modulo p and p is a prime number. I was wondering which DSP board I can use. I would want something that: 1. Be connected through USB/JTAG. 2. Can be programmed in C and has a good cross compiler, debugger and environment so that my environment is easy to use. Ideally, I would be doing this on 2-3 boards and come up with a performance analysis. Any help is appreciated. Thanks, Krushna I suggest you investigate using a PC with fast Pentium processor first especially when used in conjunction with Intel's Performance Primative library. At work, we have ceased using dedicated DSP boards, and now build ou systems based solely on Pentium CPUs. Our applications include HF Passiv Sonar, which is very demanding of processing power to run in real-time You can save megabucks taking this approach. Jeff Hi Jeff, This is more of an experiment than practical application. What we want for our performance analysis are results of the computation on say a fast Pentium processor and two-three DSP boards so that we know how useful it is to do such a thing. Since we are going to buy just a single DSP toolkit or two, cost should not be a consideration. The funding for that too is expect...

DSP evaluation board
Hello, Sorry for my english, i'm french... I am newbie with the programming of DSP. I am in the search of an DSP evaluation board which also proposes a ADC and be programmable with a C environnement. The main use of this DSP board will be training and FFT calculation by sampling 10.7 Mhz IF frequency of an HF receiver. At this moment I didn't find an evaluation board with enough powerful ADC. My choice is made on a 2812EVM-I sold at GAO TEK. but it's does not seem the best choice.

TI DSP Board
hi all, I am a postgraduate researcher based in Ireland. I am currently trying to use Matlab code developed by another researcher on a TMS320C6416 EVM. I have been trying to use the Matlab C compiler to convert the Matlab code to C and then use it in Code Composer Studio to program the chip. However this isn't working correctly. The code will compile fine in CCS but I am unable to build it. The conversion using the matlab compiler like any automatic conversion makes the C code very diificult to understand and I am beginning to think that it would be better to just manually convert the c...

Fixed Point DSP Vs Floating Point DSP

A fixed-point DSP does only fixed-point arithmetic, and usually has hardware to facilitate multiplication. A floating-point DSP has extra hardware for floating-point addition and multiplication (addition is a bit more involved than multiplication) and often omits the hardware to facilitate fixed-poing multiplication. Expect some difference in the size of a few registers. A matter of curiosity (mine): What difference had you imagined?
