A highly reliable loading method and implementation of spaceborne multi-core DSP

In order to respond to the complex intelligent processing application requirements of remote sensing satellites. Single-core DSP can no longer meet real-time requirements. TMS320C6678 is a high-performance multi-core floating-point DSP based on the KeyStone structure, with a main frequency of 1.25 GHz, which meets the needs of satellite application. Regarding the satellite use environment, whether it is FPGA or DSP, configuration loading is very important, and it is about success or failure. This article introduces the loading mode and process of TMS320C6678 in detail, and proposes a high-reliability heterogeneous loading method of Nor Flash based on EMIF16, and a program Bootloader. The test verifies that the TMS320C6678 can operate stably and reliably under the design method of this article.
