    摘要: A CAM/SRAM structure (44) performs address translations that are compatible with a segmentation/paging addressing scheme yet require only a single look-up step. Each entry in the effective-to-real-address-translator (ERAT) has two CAM fields (ESID, EPI) that independently compare an input segment identifier and an input page identifier to a stored segment identifier and a stored page identifier, respectively. The ERAT outputs a stored real address field (DATA) associated with a stored segment-stored page pair if both comparisons are equivalent. The ERAT can invalidate stored translations on the basis of segment or page granularity by requiring either a segment or a page CAM field match, respectively, during an invalidate operation.

    摘要: The present invention is directed to an apparatus for precharging complementary data circuits. The apparatus comprises two hold circuits, one for storing the data and the other for storing its complement. A signal for initiates precharging the hold circuits to the same signal level, where the signal for initiating the precharging of the hold circuits is dependent on the hold circuits' outputs.
