edaboard user pointed me to Lattice iCE40LP low end FPGA chips as an inexpensive replacement of bigger CPLDs.
Chips looks really interesting to me even though they require 1.2V, 2.5V and eventually 3.3V power supplies.
I decided to give them a try.
The chips includes nonvolatile...
I have the following engineering issue which I would like to solve using CPLD in Verilog.
I have a 16 bit data bus and I get data stream on this bus coming at f1=10KHz clock.
I want to pass this data stream to another asynchroneous f2=10Khz clock domain.
Each coming word in the f1...
I plan to integrate 3G/4G module to our system.
I have noticed that most if not all 3G/4G modules are having USB for the fast data services.
We don't have USB in our CPU system but we have 5mbit/sec uart.
Does anyone has experience with SIMCOM/TELIT/WAVECOM/Cinterion 3G or 4G modules...
Probably this question is very banal but
I would like to create a PCB as simple as possible with one Xilinx FPGA lat say from Spartan family.
I would like to create a simple download cable as well.
As a result I want to fit several simple projects in this simple development...
Is there someone which has knowledge in the area of cable modems.
Can you recommend a DOCSIS chipset manufacturer?
I would like to put the emphasis on the low price.
I would like to get your opinion about WLAN 802.11 access point design.
Is there somone which can recomend me compony which manifacture the MAC, Baseband Processor and RF Transmiter chips?
Should I use special chips for 802.11 or I can create the acces point using general purpose DSP...
I checked Matlab R14 yesterday and I am little bit disappointed.
I played with it only a day but managed to create some opinion already.
1. It is strange but new matlab can not recognize the hardware OpenGL of
my video card. I had no problem with R13 Sp1
2. The Matlab IDE...
fft fixed-point dsp 16 winograd
I have 24 long real data vector and I would like to calculate the
1,2,3,4 Fourier coefficients only. (the zero coeff is the DC term)
I would like to do this as efficiently as possible using 16 bits fixed point DSP.
What I am having in mind is...
I would like to share a practicle problem programming tms320c5509.
In large memory model the data pointers are 23 bits long so they are stored in 2 words (32 bits).
Using C if I write
pint++; //the result depend of the version of the CPU. if it...
I would like to share a problem which I am tiring to resolve already half an day without success.
So I am writing C program for the tms320c5509 using CCS 2.21.
I am using dynamical memory allocation quite intensively.
My target which I am using to test my code has only 2 LEDs...
I am doing image processing using tms320c5509 16 bit processor.
My image is 8 bit gray image (256 level of the gray).
Infortunately the c5509 can address the data in words (16 bits)
For this processor the char is 16 bit.
In addition I am in a shortage of memory so I can not afford to...
chirp signal and network analyzer
I am creating the simple network analyzer using the general purpose
Currently I am testing the system using linear chirp (tone with sweeping frequency) excitation signal x. Then I correlate the output of the system y
with x and got...
Xilinx or Altera?
Probably it is a tedious question for this forum but I am wandaring if I have to select Xilinx or Altera as a FPGA manifacturer.
The feature under concern for me are:
3. DSP Libraries
4. Connection with Mathworks' Simulink
I want to create small board using the TMS320c5509.
As far as I know both TI and Spectrum Digital have such board
and the schematics are included in their manuals. Can someone share with me the schematics of the TMS320c5509 evaluation/starter board so I can use it as a reference...
Is there someone with experience with JTAG emulators as a debugging tool for the DSP.
Is this kind of development superior the traditional KIT based?
I am interested especially for the JTAG emulation of the ADSP BF533
