Patent attributes
Circuit arrangement and method for dispatching computer instructions. In a processor having a plurality of types of execution units, the computer instructions are grouped in bundles, and each bundle includes a plurality of instructions and an associated index code. Template values are stored in a plurality of template registers, and each template value specifies types of execution units for a bundle of instructions and those instructions in a bundle that are executable in parallel. A dispatch logic circuit is coupled to the template registers and is responsive to an input bundle of instructions and associated index value. The dispatch logic circuit reads a code from a selected one of the plurality of template registers referenced by the index value and issues one or more selected instructions in the bundle to at least one execution unit of a selected type responsive to the code read from the selected one of the plurality of template registers.
