Hello.
We are advancing in our designs and now we have reached the point where more processor muscle is needed (always power-aware), so we have decided to introduce a C2000 DSP MCU (F28377S - D) within our Tiva board.
The communication between devices is going to be via SPI, however, it is interesting to us to introduce some external RAM (probably SDRAM) connected via EMIF to the DSP. We think it would be very interesting, if both CPUs could share that external RAM so many blocks of data could be readable from both CPUs at high speed. In our design the DSP would be the Master and Tiva the slave....of course some SW priorities should be introduced.
However, we are aware that Tiva devices only have an EPI peripheral for external memories.
Is it possible for te DSP and Tiva share that RAM? In the Tiva forum, some person recommended maybe a Dual port SDRAM, is it possible?
Is there any other "similar" solution? Some MBs of RAM should be enough for us.
Thank you.
