The invention discloses an FPGA-based onboard
system realization method. The method comprises the steps of S1, establishing a processor module, wherein the processor module comprises a controller anda
data path; S2, establishing an FPGA device module, wherein the FPGA device module comprises a PS / 2 interface, an RS232 interface, a VGA interface, a 7-section
LED display screen, an
LED display screen, a Switch, a Button, an on-
chip ROM, a
bus interface and IO
control logic; S3, establishing an onboard
memory module, wherein the onboard
memory module comprises a VRAM and a memory; and S4, combining circuits of the processor module, the FPGA device module and the
memory module into a
stream file, and
programming the
stream file in an FPGA. The method has the advantages in two aspects that therealization efficiency is high: hardware resources provided by the FPGA are rich, and designed computer
system hardware can be quickly realized on the FPGA, so that the realization efficiency is higher; and the flexibility is high: the FPGA is reconfigurable, so that when partial hardware parameters of the computer
system hardware are changed, reconfiguration can be performed during operation, namely, the computer
system hardware realized through the FPGA is more flexible.
