摘要:
A restriction checker generator is disclosed for generating a restriction checker capable of checking horizontal microcode instructions against restrictions which the microcode instructions must satisfy in order to be valid. The generator comprises means for transforming information representing each restriction into at least one logical test for the instruction, each logical test comprising a number of sub-tests for the values of fields of the instruction such that failure of any one of the sub-tests by an instruction indicates that the restriction is satisfied by the instruction. The sub-tests can be set-membership tests or arithmetic tests. An embodiment of the invention includes means for factorizing the logical tests so that, for at least some of the sub-tests, if the same sub-test occurs in a plurality of the logical tests, the sub-test will only be performed once for the plurality of logical tests, failure of the sub-test by an instruction indicating that each of the plurality of logical tests is satisfied.
