International Classification:

G06F 17/16
G06N 3/08

Abstract:

A tensor of a first select dimension is reformatted to provide one or more sub-tensors of a second select dimension. The reformatting includes determining a number of sub-tensors to be used to represent the tensor. The reformatting further includes creating the number of sub-tensors, in which a sub-tensor is to start on a boundary of a memory unit. Data of the tensor is rearranged to fit within the number of sub-tensors.

International Classification:

G06F 9/38
G06F 9/30
G06F 9/355

Abstract:

A system includes a branch predictor and a processing circuit configured to perform a plurality of operations including storing a skip-over offset value in the branch predictor. The skip-over offset value defines a number of search addresses of the branch predictor to be skipped. The operations further include searching the branch predictor for a branch prediction. Responsive to finding the branch prediction, the searching of the branch predictor is re-indexed based on the skip-over offset value associated with the branch prediction.

International Classification:

G06F 9/38
G06F 9/30

Abstract:

Embodiments relate to multithreaded branch prediction. An aspect includes a system for dynamically evaluating how to share entries of a multithreaded branch prediction structure. The system includes a first-level branch target buffer coupled to a processor circuit. The processor circuit is configured to perform a method. The method includes receiving a search request to locate branch prediction information associated with the search request, and searching for an entry corresponding to the search request in the first-level branch prediction structure. The entry is not allowed based on a thread state of the entry indicating that the entry has caused a problem on a thread associated with the thread state.
