AM2634: DSP In AM-2634

Tej_1441

Part Number: AM2634

Tool/software:

Hi Ti family,

Since the AM-2634 microcontroller lacks a dedicated DSP core, to address this I've integrated a library from GitHub into my project for dsp implementation.
https://github.com/UBCOrbit/CMSIS_Hercules

The time taken to perform the convolution on two data of length 4096 is coming to be 6 millisecond.

Is there any way to reduce its timing to 1ms ??

Thanks.

Hi Tej,

A few questions:

1. Is the 6ms time coming from release build binary or a debug build binary (if debug, please profile in release)

2. Is the logic for convolution placed in TCM memory or executing from RAM (Access time for TCM <= Access time for cached part of OCRAM < Access time for uncached OCRAM memory.

3. Is FPU enabled in your build? (refer: https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1213765/am2634-mcu-plus_sdk-am263x-fpu-setting)
