| Abstract: | On account of the non-standard interface of space-borne SAR data compressor and the complexity of its function-testing, this paper adopts the idea of embedded System on-Chip to design a noval type of aided testing instrument. The system utilized an embedded PowerPC405 hardware core in the FPGA to transport data and this improves the system integration completency greatly. The design flexibility was improved through building up the RAM and the peripheral contronller using the FPGA logic cells. The application shows that the system runs stably and reliably and it can be easily extended functionally by adding more peripheral controllers, and so the system can be migrated easily. |
