Abstract: A heterogeneous processor architecture and a method of booting a heterogeneous processor is described. A processor according to one embodiment comprises: a set of large physical processor cores; a set of small physical processor cores having relatively lower performance processing capabilities and relatively lower power usage relative to the large physical processor cores; and a package unit, to enable a bootstrap processor. The bootstrap processor initializes the homogeneous physical processor cores, while the heterogeneous processor presents the appearance of a homogeneous processor to a system firmware interface.

Abstract: Techniques and mechanisms for processor circuitry to execute a load and expand instruction of an instruction set to generate decompressed matrix data. In an embodiment, the instruction comprises a source operand which indicates a location from which compressed matrix data, and corresponding metadata, are to be accessed. A destination operand of the instruction indicates a location which is to receive decompressed metadata, which is generated, during execution of the instruction, based on the compressed matrix data and the corresponding metadata. The metadata comprises compression mask information which identifies which elements of the matrix have been masked from the compressed matrix data. In another embodiment, the instruction further comprises a count operand which identifies a total number of the unmasked matrix elements which are represented in the compressed matrix data.

Abstract: Embodiments detailed herein relate to matrix operations. In particular, the loading of a matrix (tile) from memory. For example, support for a loading instruction is described in at least a form of decode circuitry to decode an instruction having fields for an opcode, a source matrix operand identifier, and destination memory information, and execution circuitry to execute the decoded instruction to store each data element of configured rows of the identified source matrix operand to memory based on the destination memory information

Abstract: Implementations of using tiles for caching are detailed In some implementations, an instruction execution circuitry executes one or more instructions, a register state cache coupled to the instruction execution circuitry holds thread register state in a plurality of registers, and backing storage pointer storage stores a backing storage pointer, wherein the backing storage pointer is to reference a state backing storage area in external memory to store the thread register state stored in the register state cache.

Abstract: Instructions and logic provide advanced paging capabilities for secure enclave page caches. Embodiments include multiple hardware threads or processing cores, a cache to store secure data for a shared page address allocated to a secure enclave accessible by the hardware threads. A decode stage decodes a first instruction specifying said shared page address as an operand, and execution units mark an entry corresponding to an enclave page cache mapping for the shared page address to block creation of a new translation for either of said first or second hardware threads to access the shared page. A second instruction is decoded for execution, the second instruction specifying said secure enclave as an operand, and execution units record hardware threads currently accessing secure data in the enclave page cache corresponding to the secure enclave, and decrement the recorded number of hardware threads when any of the hardware threads exits the secure enclave.
