It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.AbstractA system and method of evaluating cache coherency protocols and algorithms in scalable symmetric multiple processor computer systems. The system includes scalable 32-byte or larger cache lines wherein one specific byte in the cache line is assigned for write and read transactions for each specific 32-bit processor. The method includes steps to ensure each 32-bit processor writes and reads to and from the specific byte in the cache line assigned to that 32-bit processor.Other References
