Abstract
A circuit arrangement decodes instructions based in part on one or more decode-related attributes stored in a memory address translation data structure such as an Effective To Real Translation (ERAT) or Translation Lookaside Buffer (TLB). A memory address translation data structure may be accessed, for example, in connection with a decode of an instruction stored in a page of memory, such that one or more attributes associated with the page in the data structure may be used to control how that instruction is decoded.
