Abstract: A method includes receiving an execute packet that includes a first instruction and a second instruction and executing the first instruction and the second instruction using a pipeline. Executing the first and second instructions includes storing a result of the first instruction in a holding register; determining whether an event that interrupts execution of the execute packet occurs prior to completion of the executing of the second instruction; and based on the event not occurring, committing the result of the first instruction after completion of the executing of the second instruction.

Abstract: A method to reverse source data in a processor in response to a vector reverse instruction includes specifying, in respective fields of the vector reverse instruction, a source register containing the source data and a destination register. The source register includes a plurality of lanes and each lane contains a data element, and the destination register includes a plurality of lanes corresponding to the lanes of the source register. The method further includes executing the vector reverse instruction by creating reversed source data by reversing the order of the data elements, and storing the reversed source data in the destination register.

Abstract: A method to store source data in a processor in response to a bit-reversed vector store instruction includes specifying, in respective fields of the bit-reversed vector store instruction, a first source register containing the source data and a second source register containing address data. The first source register includes a plurality of lanes and each lane contains an initial data element having an associated index value. The method also includes executing the bit-reversed vector store instruction by creating reordered source data by, for each lane, replacing the initial data element in the lane with the data element having a bit-reversed index value relative to the associated index value of the initial data element; and storing the reordered source data in contiguous locations in a memory beginning at a location specified by the address data.

Abstract: A method includes receiving, by a memory management unit (MMU) comprising a translation lookaside buffer (TLB) and a configuration register, a request from a processor core to directly modify an entry in the TLB. The method also includes, responsive to the configuration register having a first value, operating the MMU in a software-managed mode by modifying the entry in the TLB according to the request. The method further includes, responsive to the configuration register having a second value, operating the MMU in a hardware-managed mode by denying the request.

Abstract: Techniques related to executing a plurality of instructions by a processor comprising a method for executing a plurality of instructions by a processor. The method comprises detecting a pipeline hazard based on one or more instructions provided for execution by an instruction execution pipeline, beginning execution of an instruction, of the one or more instructions on the instruction execution pipeline, stalling a portion of the instruction execution pipeline based on the detected pipeline hazard, storing a register state associated with the execution of the instruction based on the stalling, determining that the pipeline hazard has been resolved, and restoring the register state to the instruction execution pipeline based on the determination.
