1. Introduction ASM1064, a SATA host controller(AHCI) with upstream PCIe Gen3 x1 and downstream four SATA Gen3 ports. It’s a low latency, low cost and low power AHCI controller. With four SATA ports and cascaded port multipliers, ASM1064 can enable users to build up various high speed IO systems, including server, high capacity system storage or surveillance platforms.
