摘要: A microprocessor is provided having selective control features to determine its core-to-bus clock ratio. The includes a fuse and buffer/control logic. fuse, fabricated on the microprocessor's metalization or poly layer, can be blown with laser during fabrication. When blown, provides permanent state that prescribes fixed logic coupled fuse. accepts directs set ratio fix value, thus disabling of via external signals.
