Abstract
As a performance critical (high or full speed) request for a computer system data bus travels down a central pipeline, the system detects whether the interface data bus is currently empty or there is an ongoing half-speed transfer. If there is an ongoing low speed transfer, the system dynamically time shift or slows down the read rate out of the interleave buffer to half speed, and utilizes the free half of the bandwidth. This dynamic 'zippering' or time shifting of data prevents a pipe pass from being rejected because the whole data bus is unavailable.
