Hi Delared, I am not sure this can help your goal, on IPcore an MSP430 exist and is accurate enough, you can add dual port memory interface, after first full dump using a buffer can transfer just what is changing (read write or event driven) and help trace real time of all memory.
This require a lot of VHDL coding, some peripheral need to be constructed and still some interface to a real DMA MSP can be necessary to get analog and or other processor information.
