As this was a slow calculation, special purpose arithmetic chips were developed. These circuits were developed specifically to do mathematic functions on floating point data. These were designed to be co-processors with the MPU. Generally these math co-processors were referred to as a Floating Point Processor, or <b>FPU<\/b>. Early versions of these devices would provide a single function, such multiply, and not surprisingly were referred as hardware multipliers (examples: the Intel 8321, TRW TDC1010).
