ADS8588SEVM-PDK: ADS8588SEVM-PDK

Hello,

I am working on a capstone project related to neural network application for an array processing problem as the member of a team of senior electrical engineering students. We would like to use eight microphones working simultaneously in order to evaluate beamforming algorithms. So, we need a high-speed digital signal processing unit for high speed simultaneous audio processing, which led us to decide to use EVMK2GX module manufactured by TI. On the

other hand, we are using analog microphones in order to process the audio signals more precisely by adjusting the gain. Thus, analog microphones must be connected to the mentioned DSP with an analog to digital converter (ADC). Our main problem is related to the ADC.

The ADC we are considering to use is ADS8588SEVM-PDK. However, we would like to take the digital data from ADC simultaneously to DSP(EVMK2GX) in order to process with array processing methods. Is it possible to interface the mentioned ADC ADS8588SEVM-PDK with given DSP(EVMK2GX) simultaneously with USB interface? According to the datasheets, ADS8588SEVM-PDK requires a PC connection for data acquisiton. Is there any alternative and possible connection (parallel/serial) directly from the evaluation board to DSP for the simultaneous interfacing to process the eight channel audio input precisely in the beamforming algorithms?

We would like to design our system with a strong processor unit, for which EVMK2GX seems to be very useful. Speed and precision is important in beamforming algorithms. We kindly request your profound advice on the subject of simultaneous interfacing of ADC ADS8588SEVM-PDK unit with DSP(EVMK2GX) or another TI ADC model that is compatible with the DSP and the task given above.

Thank you,

Sueda Taner

I am a senior year student in the Department of Electrical and

six electrical and electronics senior students for a capstone project

We would like to use eight microphones working simultaneously in order
to evaluate beamforming algorithms. Then, we needed a high-speed digital
signal processing unit for high speed simultaneous audio processing. As
a result, we decided to use EVMK2GX module manufactured by TI. On the
other hand, we are using analog microphones in order to process the
audio more precisely by adjusting the amplification coefficients. Thus,
analog microphones must be connected to mentioned DSP with analog to
digital converter (ADC). Our main problem is related to ADC.

The ADC we are considering to use is Texas Instruments ADS8588SEVM-PDK
module. However, we would like to take the digital data from ADC
simultaneously to DSP(EVMK2GX) in order to process with array processing
methods. Is it possible to interface the mentioned ADC ADS8588SEVM-PDK
with given DSP(EVMK2GX) simultaneously with USB interface? As we see
from the datashets, ADS8588SEVM-PDK requires a PC connection for data
acquisiton. Is there any alternative and possible connection
(parallel/serial) directly from the evalutation board(ADS8588SEVM) to
DSP for the simultaneous interfacing to process the eight channel audio
input precisely in the beamforming algorithms.

We would like to design our system with a strong processor unit, then
EVMK2GX seems very useful to us. Speed and precision is important in
beamforming algorithms. We kindly request your profound advice on the
