Abstract
Cache apparatus and method with a cache replacement strategy that preemptively evicts native code translations from a code cache, independent of a space shortage in the code cache. Replacement timing is based on detection by the dynamic translator of a change in a parameter that is indicative of either two things: 1) a change in the working set of the program being translated (a parameter such as a translation rate) or 2) a change in the paths being exercised within the current working set of the program being translated (a parameter such as or the accuracy of branch predictions). This apparatus and method is described in the context of a dynamic translator.
