Move Control Word From Coprocessor 2 |
Move Control Word From Coprocessor 2
To copy a word from a Coprocessor 2 control register to a GPR
GPR[rt] = CP2CCR[Impl]
Copy the 32-bit word from the Coprocessor 2 control register denoted by the Impl field, sign-extending it to 64 bits.
The interpretation of the Impl field is left entirely to the Coprocessor 2 implementation and is not specified by the architecture.
The result is UNPREDICTABLE if Impl specifies a register that does not exist.
temp = CP2CCR[Impl] GPR[rt] = sign_extend(temp)
