Abstract
A host interface controller having a first buffer set and a second buffer set operated in a ping-pong buffer mode by a control module to alternately work as a pre-fetch buffer set. When one buffer set between the first buffer set and the second buffer set works as the pre-fetch buffer set, the control module pre-fetches and buffers data starting from a first address of a storage device into the pre-fetch buffer set and accesses the other buffer set between the first buffer set and the second buffer set to respond to a read request that the central processing unit issues to access data of a second address of the storage device.
