Template:mpu The FastMATH-LP was a microprocessor developed by Intrinsity operating at 1 GHz. The processor incorporates a high-performance MIPS CPU along with a powerful matrix and vector math unit. This mode was a low-power (LP) version of the normal FastMATH processor, operating at half the speed.
