Please help to estimate resources of ADSP-BF592

There is a very simple task:

1. Read data (Si1, Si2) from dual channel ADC (AD9248) 14bit, 10 MHz, parallel data interface. Data are read with use of multiplexing ADC channels то PPI.

2. Sum rezults: E1+=Si1, E2+=Si2, i++.

3. If i>N send E1,E2 to UART or SPI, and E1=0, E2=0, i=0. (N=65536).

What problems can arise in case of implementation of this task on ADSP-BF592?

  • Hi,

    From the datasheet of AD9248, it looks like, the device has two PPI port interfaces (due to dual ADC). However, BF592 has single PPI port. Are you planning to multiplex the those two PPI ports externally and then connect to Blackfin PPI port?

    Other things looks fine. There may not be any problem, I believe.
