Superscalar Processor

•main components are

–Multiple ALU and FPU

–data and instruction caches

–

–superscalar since the ALU and FPU’s can operate in parallel producing more than one result per cycle

–

–e.g. IBM POWER2 - 2 FPU/ALU’s each can operate in parallel producing up to 4 results per cycle if operands are in registers
