Atomic Instruction Set and Architecture with Bus Arbitration Locking

An article of manufacture includes a non-transitory machine-readable medium. The medium includes instructions. The instructions, when read and executed by a processor, cause the processor to identify a first input instruction in a code stream to be executed, determine that the first input instruction includes an atomic operation designation, and selectively block interrupts for a duration of execution of the first input instruction and a second input instruction. The second input instruction is to immediately follow the first input instruction in the code stream.
