Claim 11:
12. A processor comprising:
a first register;
write back logic coupled to the first register and configured to write a value to the first register in response to receiving a write command and the value;
a coprocessor interface coupled to the write back logic and couplable to a coprocessor, the coprocessor interface configured to receive the write command to write the value to the first register and provide the write command and the value to the write back logic;
an execution engine coupled to the coprocessor interface, the execution engine configured to stall execution of an instruction until the value from the coprocessor is written in the first register; and
resource arbitration logic configured to prioritize between a request by the write back logic to write to a second register, and a request from the coprocessor interface for the write back logic to write the value into the first register.
