On-chip floating-point coprocessor
Supports single-precision (32 bits) and double-precision (64 bits)
Supports IEEE754-compliant data types and exceptions
Two rounding modes: Round to Nearest and Round to Zero
Handling of denormalized numbers: Truncation to zero or interrupt
generation for compliance with IEEE754
Floating-point registers: 32 bits × 16 × 2 banks
(single-precision 32 bits × 16 or double-precision 64 bits × 8) × 2 banks
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
