A co-processor is provided that comprises one or more application engines that can be dynamically configured to a desired personality. For instance, the application engines may be dynamically configured to any of a plurality of different vector processing instruction sets, such as a single-precision vector processing instruction set and a double-precision vector processing instruction set. The co-processor further comprises a common infrastructure that is common across all of the different personalities, such as an instruction decode infrastructure, memory management infrastructure, system interface infrastructure, and/or scalar processing unit (that has a base set of instructions). Thus, the personality of the co-processor can be dynamically modified (by reconfiguring one or more application engines of the co-processor), while the common infrastructure of the co-processor remains consistent across the various personalities.
