| Abstract: | OMAPL138 high-performance low-power dual-core processor provides strong support for handheld mobile devices. The paper provides the analysis for the software architecture of dual-core module DSPLink and the introduction of the methods of compiling and loading the module DSPLink based on the embeded operating system Linux. The process of installation and connection when ARM and DSP communicate with each other by the example of MSGQ is analyzed. Through the DSP/BIOS and Linux side DSPLink of MSGQ in terrace and multi-threading technology, a messaging channel is built between ARM and DSP, providing the solution of DSP side of the black-box debugging in dual-core development. |
