Problems solved by technology
However, there are still many other operations performed at the application level that fail due to interruptions. Therefore, these operations require the uninterrupted execution of a series of operations or instructions, but the application programmer cannot ensure During instruction execution, no interrupt will be generated
Application programmers are more limited to the aforementioned specific "sequence" instructions, which may not be effective in performing the desired continuation operations, since these continuation instructions are only intended to perform more general continuation operations

An apparatus and method are provided for extending a microprocessor instruction set to allow for selective suppression of interrupts at the instruction level. The apparatus includes translation logic and extended execution logic. The translation logic translates an extended instruction into corresponding micro instructions. The extended instruction has and extended prefix and an extended prefix tag. The extended prefix specifies that interrupt processing be suppressed until execution of the extended instruction is completed. The extended prefix tag is an otherwise architecturally specified opcode within an existing instruction set. The extended execution logic is coupled to the translation logic. The extended execution logic receives the corresponding micro instructions, and completes execution of the corresponding micro instructions prior to processing a pending interrupt.
Description
technical field [0001] The present invention relates to a microprocessor device that extends an existing instruction set to selectively suppress interrupts, a device that adds interrupt suppression features to an existing instruction set, and an extension of an existing instruction set related to the field of microelectronics. A method of set architecture and a device capable of performing instruction-level interrupt suppression control in a microprocessor, especially a feature capable of selectively suppressing interrupts at the instruction level incorporated into an existing microprocessor instruction set architecture Technology. Background technique [0002] The use of microprocessors has grown exponentially since their development began in the early 1970's. From its earliest applications in the fields of science and technology, to the consumer field that has now been introduced into commerce from those specialized fields such as desktop and laptop computers, video game ...
