Title: Cache memory control circuit
Inventor: OKI HIDETAKA
IPC: G06F12/08
Filed: 1992-01-14
Abstract: PURPOSE:To prevent contents registered in a cache entry from being made ineffective by an other-system coincidence process asynchronously with the process of this system by performing control for reflecting the contents of the other-system coincidence process on an own-system effective bit when processes of plural arithmetic units need to be synchronized. CONSTITUTION:An arithmetic unit 201 accesses a common memory 213 through an address bus 210 and a data bus 211. When the contents of a cache address tag memory 202 match an address and an own-system effective bit 203 is set, data are read out of a cache data memory 205. When the process needs to be synchronized with the process of the other arithmetic units 212, the arithmetic unit 201 clears the own-system bit 203 through an effective bit coincidence process control line 208 according to the contents of an other-system effective bit 204. Therefore, the contents of the cache entry are never made ineffective asynchronously by the other-system coincidence process unless the arithmetic unit of this system clearly takes a countermeasure for synchronization.

Title: Wiring path decision method and delay estimation method
Inventor: YAMAGUCHI RYUICHI
IPC: G06F17/50
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To decide a wiring path for preventing the generation of timing errors by estimating a wiring capacity with effects of adjacent wiring in a rough wiring taken into consideration. SOLUTION: A wiring graph is prepared from an object integrated circuit, and a wiring path in which a cell-to-cell wiring passes through is subjected to initial decision, based on a passing cost set in each side on the wiring graph (S21). The number of intercellular wirings passing through each side of the wiring graph is obtained as wiring congestion degree (S22), and a wiring capacity for each wiring path taking into consideration the effects of the adjacent wiring is assumed from the wiring congestion degree (S23). The presence or absence of a timing error is inspected, assuming delay (S24, S25). When the integrated circuit does not satisfy specified timing limitation, a wiring path is decided again after a wiring capacity has been reflected on a passing cost of each side (S26). Alternatively, allocation of a inter-wire distance is made to be changed (S31) or a inter-wire distance enlarged (S41) for satisfying the timing limitations.
