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 Datasheet, page 20:

    "The output data from the dual ADCs can be multiplexed onto a

    single 14-bit output bus. The multiplexing is accomplished by

    toggling the MUX_SELECT bit, which directs channel data to

    the same or opposite channel data port. When MUX_SELECT

    is logic high, the Channel A data is directed to the Channel A

    output bus, and the Channel B data is directed to the Channel B

    output bus. When MUX_SELECT is logic low, the channel data

    is reversed, that is, the Channel A data is directed to the

    Channel B output bus, and the Channel B data is directed to the

    Channel A output bus. By toggling the MUX_SELECT bit,

    multiplexed data is available on either of the output data ports."
