Abstract :
The floating point unit of a 600MHz, 60 SpecFP95 (est.), out-of-order, superscalar RISC Alpha micro-processor is described. The unit has two independent pipelines for multiply and add/subtract instructions, and iterative divide and square root circuits. It implements both IEEE and VAX data formats and is fabricated in a 2.2v, 0.35µm CMOS process.
