Original Abstract Submitted
circuitry and methods for implementing one or more predicated capability instructions are described. in certain examples, a hardware processor (e.g., core) includes a capability management circuit to check a capability for a memory access request for a memory, the capability comprising an address field for an address to be accessed by the memory access request and a bounds field that is to indicate a lower bound and an upper bound of an address space to which the capability authorizes access; a decoder circuit to decode a single instruction into a decoded single instruction, the single instruction comprising a field to indicate the capability, and an opcode to indicate: an operation to be performed for the address, that an execution circuit is to perform a first check that a condition code, that indicates a status from a previous execution of the execution circuit, is a certain value, that the capability management circuit is to perform a second check that the capability authorizes access to the address, and in response to the first check and the second check both passing, cause the execution circuit to perform the operation for the address; and the execution circuit to execute the decoded single instruction according to the opcode.
