Hello everyone, I have designed board based on TMS320VC33 DSP.I have faced some problems when running the board.System consist of flash memory access time of 70ns ,reset IC to proper start up and two regulator one of them is used to get3.3V from 5V supply and other is used to get 1.8V from 3.3V regulator output.Schottky diode is used between 3.3V and 1.8V supply voltages. First of all I tri...

Hi everyone, I am programming for the VC33 and want to optimize the way memory is currently being used for a large amount of C code. I have a couple of questions on how to make the best use of the memory capabilities of the VC33: 1) How do I ensure that two accesses occur per cycle in dual access memory? If I'm doing something like repetitive calculations on matrices, it would be...

Hello all, I design an evaluation board with TMS320C31 and i have a problem, I write a program in C and compile it with CC4.1, when i use this line : retval += *ptr & 0x00000fff; the "retval" is fill by wrong value.

Hello All, I am research student looking for control code for embedded processors/microcontrollers that use PID or LQR closed-loop feedback control. My group and I want to perform some runtime analysis on the code that we are able to stockpile to see where the majority of the processor's time is spent during normal operation. From this we hope to find some trend(s) that we can then use to ...

Hello Yosuke I did not keep the correspondance with Leonard so must work from memory. If I recall this properly the problem was with trying to set breakpoints within both an input and output interrupt service routine. Basically the host communications are also an interrupt service routine. This means that if the host interrupt is blocked data will not be communcated back to the deb...

Hello Nupur The basic principle you need to know is that you can treat address labels as simple numbers. This means you can add, subtract and (in theory) even multiply them. The absolute value of a label is however variable until it has been 'linked' to an absolute location. You can clearly see this in the TI COFF assembler listing file. Basically the linkers job is to then add th...
