The MIPS R3010 FPU
The R3010 is the FPU for the MIPS R3000 CPU. It provides high-speed floating point capability for systems based on the R3000 CPU. The organization of the FPU architecture is similar to that of the R3000 CPU, and allows for optimization of both integer and floating-point performance.
 
The R3010 FPU connects seamlessly to the R3000 CPU via the R3000 coprocessor interface CP1, and since both units receive instructions in parallel, floating-point instructions can be initiated at the same single cycle rate as fixed-point instructions.
