Cache invalidation is a process in a computer system whereby entries in a cache are replaced or removed.. It can be done explicitly, as part of a cache coherence protocol. In such a case, a processor changes a memory location and then invalidates the cached values of that memory location across the rest of the computer system.
On the IBM PC, these were signaled from the graphics card to the monitor through the polarities of one or both H- and V-sync signals sent by the video adapter. [ 5 ] Later designs supported a continuous range of scan frequencies, such as the NEC Multisync which supported horizontal scan rates from 15 to 31 kHz [ 4 ] derived from the sync signal ...
Memoization was explored as a parsing strategy in 1991 by Peter Norvig, who demonstrated that an algorithm similar to the use of dynamic programming and state-sets in Earley's algorithm (1970), and tables in the CYK algorithm of Cocke, Younger and Kasami, could be generated by introducing automatic memoization to a simple backtracking recursive ...
