Abstract: Computer systems, service processing methods, and chips are provided in this disclosure. In one implementation, a computer system comprises an interrupt status register, a permission management register, a processor, a target storage space, and a memory storing programming instructions for execution by the processor to: set a flag corresponding to the first interrupt in the interrupt status register to a first interrupt flag and a flag corresponding to the first interrupt in the permission management register to a first call flag, wherein the first interrupt flag and the first call flag indicate whether access to the target storage space is allowed, determine whether to allow the processor to access the target storage space, and obtain first information in the target storage space in a TEE mode if determining that the processor is allowed to access the target storage space; and execute the target service based on the first information.
