Abstract: Systems and methods for cache allocation with code and data prioritization. An example system may comprise: a cache; a processing core, operatively coupled to the cache; and a cache control logic, responsive to receiving a cache fill request comprising an identifier of a request type and an identifier of a class of service, to identify a subset of the cache corresponding to a capacity bit mask associated with the request type and the class of service.

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 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: A processor of an aspect includes a set of registers capable of storing packed data. An execution unit is coupled with the set of registers. The execution unit is to access the set of registers in at least two different ways in response to instructions. The at least two different ways include a first way in which the set of registers are to represent a plurality of N-bit registers. The at least two different ways also include a second way in which the set of registers are to represent a single register of at least 2N-bits. In one aspect, the at least 2N-bits is to be at least 256-bits.
