  • 1. ADSP 2181 Simulator
    I tried to run an old ADSP-2100 EZ-Kit Lite. Unfortunately, I can open and run only one window at one time when I run ADSP 2181 simulator. There is no manual on how to run the simulator in the kit. Could anybody please let me know how to open and run several windows simultaneously? Or would anyone please point to me where I can find the ADSP 2181 simulator manual? I cannot find it in the ADI website. Thanks in advance for all the help. I don't like to spend thousands of dollars on VisualDSP for my old toy.
  • 2. Reverberation Question
    Suppose I have a sound source and one microphone. I can assume that the transfer function on reaching the microphone is az^-5 (say) where z^-5 is a five step time-delay and 'a' is an attenuation factor <1. However, suppose we have just one reverberation off a nearby wall which takes 8 samples to reach the same microphone.Am I right in saying that the new transfer function (acoustic that is) is az^-5 + bz^-8 where b<a. This is beacause sound follows an inverse square law and must attenuate the further away it gets from the source. Are there any cases where b>a ie if there is a standing wave for instance? ie the smalest delay must have the largest amplitude always. Thanks Tom
  • 3. How to detect echos in a video signal ?
    Hi, I'd like some advice on how to determine if a video signal has some echos (ghost pictures) in it or not. What I have is a digital video stream (ITU-656), and I'm looking for some kind of DSP algorithm (line-based or frame-based) to solve this. Any suggestions ? Many thanks, Guy.
  • 4. easy estimate of bandwidth?
    Hi all! I would like to have an fast, easy method to esimate the bandwidth (or kind of degrees of freedom) of a given piece of signal. Lets say, if there is a sine wave, that number should be very low (or zero), if there is white noise, it should be 1 (or something defined). Signal pieces are about 200 samples long. I have a 16 bit dsp. Any idea?

2.Is "hamming code" a channel or source coding?

Hi, 

I was asked to do some research on this "hamming code" and compare its
efficiency with huffman coding? But i remember from my class and
context
book, hamming code is some kind of error correction channel coding
scheme.
As I right? if yes, how can I compare the efficiency of a channel
coding to source coding? I have already thrown away all my knowledge
from classroom.

Thanks

3.ADC using 2812

Hi,
I am trying to setup a 2812 to take A to D readings. I have the ADC
setup for 10 readings (MAXCONV=9), cascaded sequencer, continuous run,
and to branch to the ADC interrupt at the EOS (end of sequence). When
the program branches to the interrupt routine, I read and store the
result registers to variables. My problem is that the result registers
never change their value even when I vary the applied signal between 0V
and 3V. Any suggestions? Also, I have the ADC set to suspend mode0
where an emulation suspend is ignored (i.e. the ADC continues to sample
even when I hit a breakpoint?). Would this have anything to do with it?

4.flash and external ram timing on TI 2812

Hello !
Would someone be able to explain me how to calculate the execution time o
a 
NOP instruction when it is executed into flash and into external ram of 
DSP 
TI 2812?
Is it normal to have a time more important (2*) into ram than into flas
?
Is it normal to see that a change into the configuration of XINTF doesn'

change the execution time ?
Thanks a lot for your answers 

5.What not to do? TI - 2812 - FLASH

Hi all,

This is regarding flashing a code in 2812 processor from TI. I tried
flashing a sample code from spectrum digital using the SDFlash
utility. I was able to flash it a couple of times, but after that it
was consistently showing errors in flashing. Actually the probelm was
with locking and unlocking the device using CSM.

The important point to be noted as far as flashing is concerned is
that the device has to be reset once ( soft reset thru the SDFlash
utility ) and then flashed, but not the reverse. In case u accidently
reset the device after flashing, it places 0000 in all the password
locations and locks the device permanently and after that ur device
cannot be debugged or reprogrammed. In case u r using an eZDSP kit
from spectrum digital, u can download ur code through JTAG and
continue working with onchip and off chip RAM, but secure RAM
locations and FLASH memory cannot be touched. More information on the
CSM can be obtained from the TI user guide SPRU078A.
