1394 ohci chip, why design a 1394 ohci chip like this : whth mass dual port static RAM (storage=1M ,not just 2k), then link it not to PCI bus, but to CPU local bus (without DMA, directly take the 1394 ohci chip as RAM),,, i think speed will faster,,and can be used easily with embedded system (for example mpc8247 60x bus)
