Abstract
The subject invention facilitates the efficient operation of the disassembly of the microprocessor bus by providing an apparatus and method for detecting and correcting a strobe phase inversion and predrive filtering in a 2× source synchronous data transfer bus. Apparatus according to the subject invention detects a data strobe inversion in a source synchronous 2× data bus and corrects for this inversion by reordering the received data as well as filtering predrive effects in real time. Specifically, this apparatus according to the subject invention monitors bus traffic in a multiprocessor environment and correctly captures all double data rate exchanges regardless of the source IC or destination IC in the system.
