Optimizing branch re-wiring in a software instruction cache

A method includes a computer device receiving a branch instruction; the computer device managing two tables, where a first table relates to application blocks and a second table relates to available address slots; and the computer device calculating a target of the branch instruction using a branch-to-link register, the computer device optimizes re-wiring in a cache using the calculation and the managed two tables.

Latency hiding for caches

A technique for accessing a memory having a high latency portion and a low latency portion is provided. The technique includes detecting a promotion trigger to promote data from the high latency portion to the low latency portion, in response to the promotion trigger, copying cache lines associated with the promotion trigger from the high latency portion to the low latency portion, and in response to a read request, providing data from either or both of the high latency portion or the low latency portion, based on a state associated with data in the high latency portion and the low latency portion.

Asynchronous cache flushing

Proactive flush logic in a computing system is configured to perform a proactive flush operation to flush data from a first memory in a first computing device to a second memory in response to execution of a non-blocking flush instruction. Reactive flush logic in the computing system is configured to, in response to a memory request issued prior to completion of the proactive flush operation, interrupt the proactive flush operation and perform a reactive flush operation to flush requested data from the first memory to the second memory.

Cache utilization and eviction based on allocated priority tokens

A system, method, and computer program product are provided for providing prioritized access for multithreaded processing. The method includes the steps of allocating threads to process a workload and assigning a set of priority tokens to at least a portion of the threads. Access to a resource, by each one of the threads, is based on the priority token assigned to the thread and the threads are executed by a multithreaded processor to process the workload.
