Abstract
One embodiment of the present invention provides a system that facilitates atomically updating selected bits within a register in a computing system. During operation, the system receives a command to update selected bits within the register. This command includes a data word and a control bit pattern. Next, the system examines the control bit pattern to determine an operation to be performed on the register. The system then performs the operation, which involves using the dataword to modify a content of the register atomically, without blocking subsequent commands to update the register.
