| Abstract: | A design method of high reliability SDRAM controller based on FPGA is
proposed for data cache utilized in space electromagnetic environment. This
controller is modularized from top to bottom, including two layers state machine
of top control and bottom driver.Its reliability is improved by the f
unctions of power-on self-checking and critical control module triple modular re
dundancy(TMR). Finally, the FPGA hardware implementation and testing of the con
troller are completed, and the test results show that this design is high
ly reliable and flexible, which can be provided as guidance for realization of a
practical data cache system in space electromagnetic environment. |
