3.1
The FPU has the following features.
• Conforms to IEEE754 standard
• 16 single-precision floating-point registers (can also be referenced as eight double-precision
• Two rounding modes: Round to nearest and round to zero
• Denormalization modes: Flush to zero
• Five exception sources: Invalid operation, divide by zero, overflow, underflow, and inexact
• Comprehensive instructions: Single-precision, double-precision, and system control
3.2
3.2.1
A floating-point number consists of the following three fields:
• Sign (s)
• Exponent (e)
• Fraction (f)
This LSI can handle single-precision and double-precision floating-point numbers, using the
formats shown in figures 3.1 and 3.2.
