Block moves are frequent operations in modern Personal workstations. Most CISC architectures implement block move instructions, however early RISC didnt. The F-CPU architecture does not specify a Block Move Coprocessor (BMC) as part of the instruction set, but instead as a general-purpose coprocessor that will handle lengthy block move operations, freeing the main processing unit for other tasks. As with the FP coprocessor, initiating a block move command (by transferring the command word from any of the virtual registers to the BMC) takes a single instruction and a single clock cycle.
