Editing NS32000 (section)

==Swordfish==
A derivative of the NS32732 called Swordfish was aimed at [[embedded system]]s and arrived in about 1990. Swordfish has an integrated floating point unit, timers, DMA controllers and other peripherals not normally available in microprocessors. It has a 64-bit data bus and is internally overclocked from 25 to 50&nbsp;MHz. The chief architect of the Swordfish is [[Donald Alpert]], who went on to manage the architectural team designing the [[Pentium]]. The Pentium internal microarchitecture is similar to the preceding Swordfish.

The focus of Swordfish was high-end [[PostScript]] [[laser printer]]s, and performance was exceptional at the time. Competing solutions could render about one new page per minute, but the Swordfish demo unit would print out sixteen pages per minute, limited only by the laser-engine mechanics. On each page it would print out how much time it was idling, waiting for the engine to complete.

The Swordfish die is huge, and it was eventually decided to drop the project altogether, and the product never went into production. The lessons from the Swordfish were used for the CompactRISC designs. In the beginning, there were both a CompactRISC-32 and a CompactRISC-16, designed using "Z". National never brought a chip to the market with the CompactRISC-32 core. National's Research department worked with the University of Michigan to develop the first synthesizable Verilog Model, and Verilog was used from the CR16C and onwards.
