For a long time, most developers could not make good use of DSP comprised in the OMAP architecture of the Pandora SoC. Sure, there was TI’s dispbridge driver in the Pandora firmware for a long time, and a few developers like MH-T or Hdonk tried to make use of it – but the key issue was always linked with the latency to call the DSP or high CPU usage. Then BSP came with his deep knowledge of the architecture, and was able to package a kernel driver, a DSP component and an ARM library to make better use of it. Unfortunately, while the DSP can certainly help to relieve your CPU of certain tasks , it requires to re-factor your code and separate it into parallel processes to be used in concurrence with the main program thread. With the exception of a few demos by BSP, MH-T and Hdonk, no one had yet fully completed that kind of work. Notaz’s latest PCSXReARMed build now makes full use of that architecture.
