The present invention discloses an instruction processing apparatus, including: a first register adapted to store address information; a second register adapted to store address space identification information; a decoder adapted to receive and decode a translation lookaside buffer flush instruction, where the translation lookaside buffer flush instruction indicates that the first register serves as a first operand, and the second register serves as a second operand; and an execution unit coupled to the first register, the second register, and the decoder and executing the decoded translation lookaside buffer flush instruction, so as to acquire address information from the first register, to acquire address space identification information from the second register, and to broadcast the acquired address, information and address space identification information on a bus coupled to the instruction processing apparatus, so that another processing unit coupled to the bus performs purging on a translation lookaside buffer, corresponding to the address information, in an address space indicated by the address space identification information. The present invention also discloses a corresponding instruction processing method, a computing system, and a system-on-chip.

Processing method and apparatus for translation lookaside buffer flush instruction

A first logic circuit included in a processor receives a first digital signal, where the first logic circuit includes a special purpose register, a comparator, and an adder, where the special purpose register stores a first resource balance for executing a smart contract, where the first digital signal includes a resource deduction quota corresponding to a code set in the smart contract. The first logic circuit reads the first resource balance from the special purpose register. The first logic circuit compares, using the comparator, the first resource balance with the resource deduction quota. In response to the first resource balance being greater than or equal to the resource deduction quota, the first logic circuit subtracts, using the adder, the resource deduction quota from the first resource balance to obtain a second resource balance. The first logic circuit stores the second resource balance in the special purpose register.
