Hi, I'm new here and I've some problems with a board developped by my predecessor. This board is based on a 56303 which is now faulty due to manipulation error. So 4im currently looking for a knew one but I've real difficulties to find one. Doe

hi-need a small help regarding the calculation of maximum rate that a dsp 56002/56303 can read through the ssiport of dsp56002.and essi of dsp56303. as i want to interface the A/D chip to these devices.

As the subject says, Looking for a 56002 EVM module for a 4th year design project. Anyone have one lying around collecting dust? Due to my small (student) budget I can't afford the newer 56303 EVM. But if you have one (or a schematic) for sale I would be interested as we

Hi all Does anyone know how long in clock cycles it takes for an interrupt to be serviced form the time that the interrupt occurs? I have set up one of my host port pins as an output and am using the timer1 compare interrupt to toggle that pin. If I set the reload value

hi, i want to know, is it possible to use ADC of around 70-100MHz sampling frequency with the dsp 56303 by using the digital down converter in between the ADC and the DSP.  since the ADC of such a sampling frequency come with the parallel output only and the dsp56303 will not sup

I have a strange problem with the tools. I've searched the documentation to no avail. When I assemble the output from the compiled source files, I get the error "ERROR --- Instruction cannot appear immediately after control register access or an ENDDO (Opcode field)". This error refers to the following code snippet where the given line number is the "rts" instruction at the end of the functio...

I think it depends a lot on how fast your interrupt service routine winds up being. If you have total control over bit times and inter-character-gaps on the sending device, you could make it as fast or as slow as your DSP chip can handle. I doubt if the "line speed"

I want to use address trace mode on the 56321 and 56303 so that I can watch internal Pmem fetches with a logic analyzer. I would like to use the logic analyzer in a mode where it is clocked from the DSP. Is there any signal from the DSP that I could use for this?

Are the ESSI ports fully simulated in the gui56300 simulator (part of Suite56) ? I'm trying to simulate some code that is controlled by the ESSI ports...I set the ESSI ports in network mode, and then synchronize the code to the timing of the ESSI data by polling the TFS flag in the status register. For this and other reasons, it is important that I
