METHOD AND APPARATUS FOR CONNECTING BUSES WITH DIFFERENT CLOCK FREQUENCIES |
摘要 |
A method and an apparatus in a computer system for connecting buses with different clock frequencies are provided. The method comprises receiving a request transmitted from a master to a slave. If the clock frequency of the master is lower than that of the slave such that the slave sees more requests than the master does, redundant cycles of the request signal are masked lest the slave repeatedly receive the request. The request is then transferred to the slave. If the clock frequency of the master is higher than that of the slave such that the slave cannot receive the request in time, then the request signal is lengthened so that the request signal is synchronized with the clock cycles of the slave. The output data responded from the slave is then transferred to the master.
