•
32-bit CPU-FPU floating-point communication register (FPUL)
•
Supports FMAC (multiply-and-accumulate) instruction
•
Supports FDIV (divide) and FSQRT (square root) instructions
•
Supports FLDI0/FLDI1 (load constant 0/1) instructions
•
Instruction execution times
Latency (FADD/FSUB): 3 cycles (single-precision), 5 cycles (double-
precision)
Latency (FMAC/ FMUL): 5 cycles (single-precision), 7 cycles (double-
precision)
