A lightweight DSP framework for OMAP3530-driven embedded devices

This thesis provides a lightweight framework, called MiniDSP, for OMAP3530 heterogeneous dual core SoC to run tasks on its DSP co-processor. This framework is composed of a minimal DSP kernel and a set of programs which run on the ARM A8 master processor. The minimal kernel maintains system stability and initializes the interrupt handler. The set of programs includes a DSP device driver, a host program and two utility programs. Through the device driver, the ARM core can send commands to the DSP and control it to execute compute-intensive applications. The host program performs task o -loading and general ARM-DSP communication. Finally the two utility programs are responsible for converting the DSP executable to a bootable format used by the framework. This framework is open source, highly con figurable and lightweight, enabling the possibility of high performance computing on DSP.
