Abstract
A processor core, comprises one or more vector units operable to change between a fine-grained vector mode having a shorter maximum vector length and a coarse-grained vector mode having a longer maximum vector length. Changing vector modes comprises halting all instruction stream execution in the core, flushing one or more registers in a register space, reconfiguring one or more vector registers in the register space, and restarting instruction execution in the core.
