Abstract :
We have designed an SoC platform with a multi-channel bus architecture which can reduce the bottleneck of on-chip communication by multi-channels. The platform consists of OpenRISC 1200 processor, WISHBONE crossbar on-chip bus, memory interface, VGA controller, DMA, AC97 controller, debug interface and UART. The crossbar on-chip bus supports up to 8 masters and 16 slaves, WISHBONE compatible peripheral IPs and allows more than one master to use the bus because of multiple channels. The proposed platform is implemented on Altera´s EP2C70F672 FPGA device. As a result of the test program, the proposed platform has better efficiency by 26.58% than the SoC platform with shared bus on-chip bus.
