Abstract
A processing pipeline may have first and second execution circuits having different performance or energy consumption characteristics. Instruction supply circuitry may support different instruction supply schemes with different energy consumption or performance characteristics. This can allow a further trade-off between performance and energy efficiency. Architectural state storage can be shared between the execute units to reduce the overhead of switching between the units. In a parallel execution mode, groups of instructions can be executed on both execute units in parallel.
