Abstract
A computer system supporting N different machine views, where N.gtoreq.2, includes a memory for storing instructions, a number of execution units for processing data based on execution controls, and N different decoders for generating the execution controls using instructions retrieved from the memory. Each of the N decoders is operative to decode retrieved instructions in accordance with one of the N machine views. A particular one of the N decoders to be used to decode a given retrieved instruction may be selected by a program running on the system. In one embodiment, the decoders for the N machine views are implemented as N separate decoders, and a multiplexer is used to select the output of one of the N decoders for connection to one or more of the execution units. In another embodiment, a set of reconfigurable hardware is dynamically reprogrammed to implement one or more of the N decoders as directed by the program running on the system.
