957 results about "Wait state" patented technology

A wait state is a delay experienced by a computer processor when accessing external memory or another device that is slow to respond. Computer microprocessors generally run much faster than the computer's other subsystems, which hold the data the CPU reads and writes. Even memory, the fastest of these, cannot supply data as fast as the CPU could process it. In an example from 2011, typical PC processors like the Intel Core 2 and the AMD Athlon 64 X2 run with a clock of several GHz, which means that one clock cycle is less than 1 nanosecond (typically about 0.3 ns to 0.5 ns on modern desktop CPUs), while main memory has a latency of about 15–30 ns. Some second-level CPU caches run slower than the processor core.

Ipnet gateway

The IPNet Gateway (IPNGw) is a new technology that maps multiple servers on a private IP network to a single IP address on the Internet. As requests come in for DNS resolution of the server's domain name, the IPNet Gateway records the domain of the requesting client and the name of the requested server, and returns its own address as the destination address for the requested domain name. This DNS response is set as non-cacheable to prevent the association between the IPNGw IP address and the domain name of the target server beyond the anticipated following transaction from the client. As soon as the IPNGw responds to the DNS request it enters into a waiting state anticipating a connection from the client to the specific server identified in the DNS request. Subsequently, the client establishes a connection with the IPNGw, which in turn relays the connection request to the server.

Crossbar switch that supports a multi-port slave device and method of operation

A crossbar switch (12) arbitrates for access from multiple bus masters (14, 16, 18, 20 and 22) to multiple addressed slave ports (3 and 4) that have overlapping address ranges. In one form, the address ranges are the same address range. The crossbar switch (12) uses shared slave port control circuitry (48), configuration registers (46) and slave port arbiter logic (34, 36, 38, 40, 42 and 44) to arbitrate for access when all the addressed ports are busy. A determination is made as to whether new access requests are higher or lower in priority than existing accesses. A determination on where to direct a new access request is made based upon a prediction of which of certain multiple accesses will complete first based on various factors including the number of data beats requested as well as wait state information. In one mode, the wait state information is determined dynamically.

Methods and apparatus for managing plug-in services

Methods and apparatus operate in a computer system to manage initiation and operation of plug-in modules providing plug-in services. The plug-in manager obtains identities of a plurality of plug-in modules and retrieves a dependency list indicating respective plug-in services provided by, and required by, each plug-in module identified in the identities of the plug-in modules. The plug-in manager then calculates a plug-in initiation order based upon the dependency list indicating respective plug-in services provided by, and required by, each plug-in module. The plug-in manager then initiates service operation of plug-in modules according to the plug-in initiation order, such that if a first plug-in module provides a service required by a second plug-in module, the first plug-in module is initiated such that the service provided by the first plug-in module is available to the second plug-in module when required by the second plug-in module. In addition, the plug-in manager can operate a wait state operation within plug-in modules that provide services that depend upon each other in order to avoid service deadlocked situations.

Handling cache misses by selectively flushing the pipeline

An apparatus and method for efficiently managing data cache load misses is described in connection with a multithreaded, pipelined multiprocessor chip. A CMT processor keeps track of load misses for each thread by issuing a load miss signal each time a load instruction to the data cache misses. A detection logic functionality in the IFU responds the load miss signal to determine if a valid instruction from the thread is at the one of the pipeline stages. If no instructions from the thread are detected in the pipeline, then no flush is required and the thread is placed in a wait state until the requested data is returned from higher order memory. If any instruction from the thread is detected in the pipeline, the thread is flushed and the instruction is re-fetched.

Serializing event handling in a threaded system with no wait states

Event handling in multinode data processing networks, in which data structures are shared between nodes and are subject to concurrent requests for access, is facilitated through the use of a separate small data structure (bit array or linked list) which permits an event handler to hand off the task of accessing the data structure to an event handler which is already accessing data from the same data structure. This eliminates the need for locking arrangements and / or the use of special coordinating event handlers.
