Abstract: Various integrated circuit voltage regulation apparatus and methods of assembling the same are provided. In one aspect, an apparatus is provided that has a stack that includes a heat sink and a semiconductor chip. The semiconductor chip has a conductive heat transfer pathway to the heat sink. A voltage regulator member is electrically coupled to the semiconductor chip and coupled to the heat sink, but is not positioned in the stack.

Abstract: A generic NUMA-compliant memory selection technique is provided to enable a device capable of accessing memory anywhere in a system to select a near (potentially the nearest) memory for use with the device. For example, an AGP controller can access system memory anywhere within a multiprocessing node system, but will operate more efficiently, and interfere less with other data transactions, if it locates the closest memory, determines the memory addresses corresponding to the closest memory, and locks (or otherwise allocates) memory addresses for AGP functionality within the range of determined addresses in the near memory.

Abstract: The present application describes a system and method of profiling a computer system based on a profiling state machine. The profiling state machine defines various states in which the system data can be collected for a particular application. The state machine allows system data collection regardless of timing intervals or event counters. When a state is identified for system data collection, the profiler application collects system data for the user. A profiling application driver monitors the state machine and manages the data collection based on the state machine. The profiling application driver controls the profiling configurations thus allowing a correlated data collection for timing intervals and event counter.

Abstract: In some embodiments, present invention describes a system and method of dynamically programming HT tables in multiprocessor systems. HT tables are dynamically reprogrammed to modify the topology of the multiprocessor system for fault adjustment, diagnostic, performance analysis, processor hot plugging and the like. HT links can be isolated by reconfiguring the HT tables which allows diagnostics on the isolated HT links. HT links can be reconfigured to route packet traffic on certain links which allows the performance measurement for the HT links. HT tables can be reconfigure to isolate a processor so that the processor can be replaced without taking the entire system down.
