3.1
The FPU has the following features.
• Designed to meet IEEE754 standard
• 32 single-precision floating-point registers (can also be referenced as 16 double-precision
• Two rounding modes: Round to Nearest and Round to Zero
• Two denormalization modes: Flush to Zero and Treat Denormalized Number
• Six exception sources: FPU Error, Invalid Operation, Divide By Zero, Overflow, Underflow,
• Comprehensive instructions: Single-precision, double-precision, graphics support, and system
When the FD bit in SR is set to 1, the FPU cannot be used, and an attempt to execute an FPU
instruction will cause an FPU disable exception.
3.2
3.2.1
A floating-point number consists of the following three fields:
• Sign (s)
• Exponent (e)
• Fraction (f)
The FPU can handle single-precision and double-precision floating-point numbers, using the
formats shown in figures 3.1 and 3.2.
