6.3 FPU Programming Model
Floating-Point Control Registers
The FPU has 32 control registers (FCRs) that can only be accessed by move operations. The FCRs are described below:
- The Implementation/Revision register (FCR0) holds revision information about the FPU.
- The Control/Status register (FCR31) controls and monitors exceptions, holds the result of compare operations, and establishes rounding modes.
- FCR1 to FCR30 are reserved.
Table 6-1 lists the assignments of the FCRs.
