摘要： A processor core and method for managing program counter redirection in an out-of-order processor pipeline. In one embodiment, the pipeline of the processor core includes a front-end instruction fetch portion, a back-end instruction execution portion, and pipeline control logic. Operation of the instruction fetch portion is decoupled from operation of the instruction execution portion. Following detection of a control transfer misprediction, operation of the instruction fetch portion is halted and instructions residing in the instruction fetch portion are invalidated. When the instruction associated with the misprediction reaches a selected pipeline stage, instructions residing in the instruction execution portion of the pipeline are invalidated and the flow of instructions from the instruction fetch portion to the instruction execution portion of the processor pipeline is restarted. A mispredict instruction identification checker and instruction identification tags are used to determine if a control transfer instruction is permitted to redirect instruction fetching.

摘要： Apparatuses, systems, and methods for detecting and preventing write-after-write hazards, and applications thereof. In an embodiment, a load/store queue of a processor stores a first register destination value associated with a graduated load instruction. A graduation unit of the processor broadcasts a second register destination value associated with a graduating load instruction. Control logic coupled to the load/store queue and the graduation unit compares the first register destination value to the second register destination. If the first register destination value and the second register destination value match, the control logic prevents the graduated load instruction from altering an architectural state of the processor.

摘要： A conditional move instruction implemented in a processor by forming and processing two decoded instructions, and applications thereof. In an embodiment, the conditional move instruction specifies a first source operand, a second source operand, and a third operand that is both a source and a destination. If the value of the second operand is not equal to a specified value, the first decoded instruction moves the third operand to a completion buffer register. If the value of the second operand is equal to the specified value, the second decoded instruction moves the value of the first operand to the completion buffer. When the decoded instruction that performed the move graduates, the contents of the completion buffer register is transferred to a register file register specified by the third operand.

摘要： A RISC processor having a data mover engine and instructions that associate register addresses with memory addresses. In an embodiment, the instructions include a read-tie instruction, a single write-tie instruction, a dual write-tie instruction, and an untie instruction. The read-tie, single write-tie, and dual write-tie instructions are used to associate software accessible register addresses with memory addresses. These associations effect the operation of the data mover engine such that, for the duration of the associations, the data mover engine routes data to and from associated memory addresses and the execution unit of the processor in response to instructions that specify moving data to and from the associated register addresses. The invention reduces the number of instructions and hardware overhead associated with implementing program loops in a RISC processor.

摘要： Various methods are provided for distributing datagrams over telecommunications networks. According to many of these methods, datagrams are multicast or broadcast to one or more nodes or Virtual Local Area Networks (VLANs) on the networks. Also provided are systems for distributing datagrams over the networks according to these methods. According to some of these systems, reductions are provided in the amounts of memory used to multicast and/or broadcast datagrams.
