Abstract: Disclosed embodiments relate to systems and methods for performing 16-bit floating-point vector dot product instructions. In one example, a processor includes fetch circuitry to fetch an instruction having fields to specify an opcode and locations of first source, second source, and destination vectors, the opcode to indicate execution circuitry is to multiply N pairs of 16-bit floating-point formatted elements of the specified first and second sources, and accumulate the resulting products with previous contents of a corresponding single-precision element of the specified destination, decode circuitry to decode the fetched instruction, and execution circuitry to respond to the decoded instruction as specified by the opcode.

Abstract: Disclosed embodiments relate to systems and methods for performing instructions specifying ternary tile operations. In one example, a processor includes fetch and decode circuitry to fetch and decode an instruction specifying a ternary tile operation, and locations of destination and first, second, and third source matrices, each of the matrices having M rows by N columns; and execution circuitry to respond to the decoded instruction by, for each equal-sized group of K elements of the specified first, second, and third source matrices, generate K results by performing the ternary tile operation in parallel on K corresponding elements of the specified first, second, and third source matrices, and store each of the K results to a corresponding element of the specified destination matrix, wherein corresponding elements of the specified source and destination matrices occupy a same relative position within their associated matrix.

Abstract: Method and system for performing data movement operations is described herein. One embodiment of a method includes: storing data for a first memory address in a cache line of a memory of a first processing unit, the cache line associated with a coherency state indicating that the memory has sole ownership of the cache line; decoding an instruction for execution by a second processing unit, the instruction comprising a source data operand specifying the first memory address and a destination operand specifying a memory location in the second processing unit; and responsive to executing the decoded instruction, copying data from the cache line of the memory of the first processing unit as identified by the first memory address, to the memory location of the second processing unit, wherein responsive to the copy, the cache line is to remain in the memory and the coherency state is to remain unchanged.

Abstract: Suspendable load address tracking inside transactions is disclosed. An example processing device of implementations of the disclosure includes a transactional memory (TM) read set tracking component circuitry to identify a suspend read tracking instruction within a transaction executed by the processing device, mark load instructions occurring in the transaction subsequent to the identified suspend read tracking instruction with a suspend attribute, wherein the addresses corresponding to the marked load instructions are excluded from a read set maintained for the transaction, identify a resume read tracking instruction within the transaction, and stop marking the load instructions occurring subsequent to the identified resume read tracking instruction with the suspend attribute.

Abstract: An example system on a chip (SoC) includes a processor, a cache, and a main memory. The SoC can include a first memory to store data in a memory line, wherein the memory line is set to an invalid state. The processor can include a processor coupled to the first memory. The processor can determine that a data size of a first data set received from an application is within a data size range. The processor can determine that an aggregate data size of the first data set and a second data set received from the application is at least a same data size as data size of the memory line. The processor can perform an invalid-to-modify (I2M) operation to change the memory line from the invalid state to a modified state. The processor can write the first data set and the second data set to the memory line.

Abstract: A method of analyzing aborts of transactional execution transactions. Starting a transactional execution transaction with a first logical processor. Performing, with a second logical processor, store to memory instructions, while the first logical processor is performing the transactional execution transaction. Capturing memory addresses of, and instruction pointer values associated with, at least a sample of the store to memory instructions. Performing, with the second logical processor, a first store to memory instruction to a first memory address, which is to cause the transactional execution transaction to abort. Capturing the first memory address. Determining an instruction pointer value associated with the first store to memory instruction by correlating at least the captured first memory address with the captured memory addresses of said at least the sample of the store to memory instructions.
