Abstract: A processor includes N-bit registers and a decode unit to receive a multiple register memory access instruction. The multiple register memory access instruction is to indicate a memory location and a register. The processor includes a memory access unit coupled with the decode unit and with the N-bit registers. The memory access unit is to perform a multiple register memory access operation in response to the multiple register memory access instruction. The operation is to involve N-bit data, in each of the N-bit registers comprising the indicated register. The operation is also to involve different corresponding N-bit portions of an M×N-bit line of memory corresponding to the indicated memory location. A total number of bits of the N-bit data in the N-bit registers to be involved in the multiple register memory access operation is to amount to at least half of the M×N-bits of the line of memory.

Abstract: Embodiments of an invention a processor architecture are disclosed. In an embodiment, a processor includes a decoder, an execution unit, a coherent cache, and an interconnect. The decoder is to decode an instruction to zero a cache line. The execution unit is to issue a write command to initiate a cache line sized write of zeros. The coherent cache is to receive the write command, to determine whether there is a hit in the coherent cache and whether a cache coherency protocol state of the hit cache line is a modified state or an exclusive state, to configure a cache line to indicate all zeros, and to issue the write command toward the interconnect. The interconnect is to, responsive to receipt of the write command, issue a snoop to each of a plurality of other coherent caches for which it must be determined if there is a hit.

Abstract: Embodiments of an invention for monitoring the operation of a processor are disclosed. In one embodiment, a system includes a processor and a hardware agent external to the processor. The processor includes virtualization logic to provide for the processor to operate in a root mode and in a non-root mode. The hardware agent is to verify operation of the processor in the non-root mode based on tracing information to be collected by a software agent to be executed by the processor in the root mode.

Abstract: A processor includes a first mode where the processor is not to use packed data operation masking, and a second mode where the processor is to use packed data operation masking. A decode unit to decode an unmasked packed data instruction for a given packed data operation in the first mode, and to decode a masked packed data instruction for a masked version of the given packed data operation in the second mode. The instructions have a same instruction length. The masked instruction has bit(s) to specify a mask. Execution unit(s) are coupled with the decode unit. The execution unit(s), in response to the decode unit decoding the unmasked instruction in the first mode, to perform the given packed data operation. The execution unit(s), in response to the decode unit decoding the masked instruction in the second mode, to perform the masked version of the given packed data operation.

Abstract: A processor includes a memory to hold a buffer to store data dependencies comprising nodes and edges for each of a plurality of micro-operations. The nodes include a first node for dispatch, a second node for execution, and a third node for commit. A detector circuit is to queue, in the buffer, the nodes of a micro-operation; add, to determine a node weight for each of the nodes of the micro-operation, an edge weight to a previous node weight of a connected micro-operation that yields a maximum node weight for the node, wherein the node weight comprises a number of execution cycles of an OOO pipeline of the processor and the edge weight comprises a number of execution cycles to execute the connected micro-operation; and identify, as a critical path, a path through the data dependencies that yields the maximum node weight for the micro-operation.
