FIELD OF THE INVENTION The present invention is related to computing systems, and more particularly to a system and method for adjusting to changes in processor performance. BACKGROUND INFORMATION Designers of mobile computing platforms are faced wit…

The prioritization of large memory page mapping is a function of the access bits in the L1 page table. In a first phase of operation, the number of set access bits in each of the L1 page tables is counted periodically and a current count value is cal…

BACKGROUND INFORMATION An embodiment of the present invention relates generally to virtualization platforms and, more specifically, to a system and method to run components of a virtual machine monitor at a reduced privilege level. Various mechanisms…

A system and method in one embodiment includes modules for detecting an access attempt to a critical address space (CAS) of a guest operating system (OS) that has implemented address space layout randomization in a hypervisor environment, identifying…

In one embodiment, a method includes transitioning control to a virtual machine (VM) from a virtual machine monitor (VMM), determining that a VMM timer indicator is set to an enabling value, and identifying a VMM timer value configured by the VMM. Th…

An apparatus, system, and method are provided for automatically minimizing Real-Time (RT) task latency and maximizing Non-Real Time (NRT) task throughput. The apparatus may include a task manager, a determination module, and optionally a tracking mod…

A processor of a plurality of processors includes a processor core and a message manager. The message manager is in communication with the processor core. The message manager to receive a message from a second processor of the plurality of processors…

Aspects of the invention relate to improvements to the Least Recently Used (LRU) cache replacement method. Weighted LRU (WLRU) and Compact Weighted LRU (CWLRU) are CPU cache replacement methods that have superior hit rates to LRU replacement for prog…

A data processor supports the use of multiple memory models by computer programs. At a device external to a data processor, such as a memory controller, memory transactions requests are received from the data processor. Each memory transaction reques…

A binary search tree is provided for efficiently organizing values for a set of items, even when values are duplicated. In generating the binary search tree, the value of each item in a set of values is determined. If a particular value is unique and…
