Abstract: In accordance with embodiments disclosed herein, there is provided systems and methods for using thresholds to gate timing packet generation in a tracing system (TS). For example, the method may include generating and outputting a trace data (TD) packet into a packet log. The method also includes generating and outputting a timing packet (TM) corresponding to the TD packet into the packet log when a number of clock cycles elapsed since an output of a previous TM packet exceeds a clock threshold value.

Abstract: An apparatus is described having instruction execution logic circuitry to execute first, second, third and fourth instruction. Both the first instruction and the second instruction insert a first group of input vector elements to one of multiple first non overlapping sections of respective first and second resultant vectors. The first group has a first bit width. Each of the multiple first non overlapping sections have a same bit width as the first group. Both the third instruction and the fourth instruction insert a second group of input vector elements to one of multiple second non overlapping sections of respective third and fourth resultant vectors. The second group has a second bit width that is larger than said first bit width. Each of the multiple second non overlapping sections have a same bit width as the second group.

Abstract: Methods and apparatus are disclosed using an index array and finite state machine for scatter/gather operations. Embodiment of apparatus may comprise: decode logic to decode scatter/gather instructions and generate micro-operations. An index array holds a set of indices and a corresponding set of mask elements. A finite state machine facilitates the scatter operation. Address generation logic generates an address from an index of the set of indices for at least each of the corresponding mask elements having a first value. Storage is allocated in a buffer for each of the set of addresses being generated. Data elements corresponding to the set of addresses being generated are copied to the buffer. Addresses from the set are accessed to store data elements if a corresponding mask element has said first value and the mask element is changed to a second value responsive to completion of their respective stores.

Abstract: The present disclosure is directed to systems and methods for performing one or more operations on a two dimensional tile register using an accelerator that includes a tiled matrix multiplication unit (TMU). The processor circuitry includes reservation station (RS) circuitry to communicatively couple the processor circuitry to the TMU. The RS circuitry coordinates the operations performed by the TMU. TMU dispatch queue (TDQ) circuitry in the TMU maintains the operations received from the RS circuitry in the order that the operations are received from the RS circuitry. Since the duration of each operation is not known prior to execution by the TMU, the RS circuitry maintains shadow dispatch queue (RS-TDQ) circuitry that mirrors the operations in the TDQ circuitry. Communication between the RS circuitry 134 and the TMU provides the RS circuitry with notification of successfully executed operations and allows the RS circuitry to cancel operations where the operations are associated with branch mispredictions and/or non-retired speculatively executed instructions.

In one embodiment, a processor includes fetch circuitry to fetch a single instruction having fields to specify an opcode and locations of a source vector comprising N plurality of 16-bit half-precision floating-point elements, and a destination vector to store N plurality of 16-bit bfloat floating-point elements, the opcode to indicate execution circuitry is to convert each of the elements of the source vector from 16-bit half-precision floating-point format to 16-bit bfloat floating-point format and store each converted element into a corresponding location of the destination vector, decode circuitry to decode the fetched single instruction into a decoded single instruction, and the execution circuitry to respond to the decoded single instruction as specified by the opcode.
