Abstract: A dynamic memory control method for clusters includes at least one processor core and for cache memories each belonging to a corresponding cluster of the clusters. The dynamic memory control method includes borrowing a first portion of cache memory from a first cache memory and/or a second portion of cache memory from a second cache memory to allow the first portion and/or the second portion of cache memory to be utilized as a temporary internal RAM, and returning the first portion of cache memory to the first cache memory and/or the second portion of cache memory to the second cache memory such that each of the first portion and/or the second portion of cache memory is exclusively used by the at least one processor core of the first cluster and/or the second cluster.

Abstract: A device selectively executes native machine code of a computing method in an application. Prior to execution of the application, a predicted usage level of the computing method is determined based on available statistical analysis data of the computing method. According to a determination of whether the predicted usage level exceeds a threshold, a selector selects executable code of the computing method for execution. The executable code is the native machine code or bytecode of the computing method. When the computing method is called during execution of the application, the selected executable code is loaded from non-volatile storage into memory for execution by a virtual machine. Furthermore, runtime usage level of the computing method is monitored to determine whether to switch from bytecode to native machine code execution.
