摘要:
A conditional instruction architected to receive one or more operands as inputs, to output to a target the result of an operation performed on the operands if a condition is satisfied, and to not provide an output if the condition is not satisfied, is executed so that it unconditionally provides an output to the target. The conditional instruction obtains the prior value of the target (that is, the value produced by the most recent instruction preceding the conditional instruction that updated that target). The condition is evaluated. If the condition is satisfied, an operation is performed and the result of the operation output to the target. If the condition is not satisfied, the prior value is output to the target. Subsequent instructions may rely on the target as an operand source (whether written to a register or forwarded to the instruction), prior to the condition evaluation.

A Branch Target Address Cache (BTAC) stores at least two branch target addresses in each cache line. The BTAC is indexed by a truncated branch instruction address. An offset obtained from a branch prediction offset table determines which of the branch target addresses is taken as the predicted branch target address. The offset table may be indexed in several ways, including by a branch history, by a hash of a branch history and part of the branch instruction address, by a gshare value, randomly, in a round-robin order, or other methods.

A computer-based training (CBT) system using versatile resources to support multiple training scenarios in a multi-user environment. The CBT system includes an authoring program module accessible by a lesson designer to create a number of lessons. The CBT system includes one or more runner program modules accessible by lesson takers for running the lessons created with the authoring program module. The CBT system also includes a relational database accessible by the runner program modules and comprises administrative information and information for retrieving desired resources. The versatile resources of the present invention reduce the memory storage requirements for a CBT system capable of supporting multiple training scenarios in a multi-user network environment. The CBT system realistically simulates multi-mode communication systems and implements progressive mentoring and voice-based progression methodologies.

Method and apparatus for increasing the number of real memory addresses accessible through a translational look-aside buffer (TLB) by a multi thread CPU. The buffer entries include a virtual address, a real address and a special mode bit indicating whether the address represents one of a plurality of threads being processed by the CPU. If the special mode bit is set, the real address associated with the virtual address higher order bits are concatenated with the thread identification number being processed to obtain a real address. Buffer entries containing no special mode bit, or special mode bit set to 0, are processed by using the full length of the real address associated with the virtual address stored in the look-aside buffer (TLB).
摘要:
A method for optimizing throughput in a microprocessor that is capable of processing multiple threads of instructions simultaneously. Instruction issue logic is provided between the input buffers and the pipeline of the microprocessor. The instruction issue logic speculatively issues instructions from a given thread based on the probability that the required operands will be available when the instruction reaches the stage in the pipeline where they are required. Issue of an instruction is blocked if the current pipeline conditions indicate that there is a significant probability that the instruction will need to stall in a shared resource to wait for operands. Once the probability that the instruction will stall is below a certain threshold, based on current pipeline conditions, the instruction is allowed to issue.

Techniques are described for identifying a wireless access point device using beacon messages and probe responses. An access point may generate and broadcast beacon messages which include an information element containing information specific to the device as well as to the current context of the device. For example, the information element may include a device vendor ID, product ID, and a device-unique ID. That is, the information element provides information related to the device itself independently from the configuration of the wireless network which the beacon message (or probe response) is associated with.

A wall module for a modular wall structure integrates a wall panel portion with a post portion having top or upper and bottom or lower extensions and at least one groove for receiving a distal end of a wall panel portion of an adjacent module. The bottom/lower extension is set within an exposed portion of a reinforcing cage of a caisson or pier extending below grade and encapsulated with a material such as concrete to integrate the caisson or pier with the bottom/lower post extension. Integration of the caisson or pier with the module provides numerous economies of transportation, construction and repair and improved safety. The top/upper post extension is of a length to accommodate the full height of the wall panel portion of an adjacent module to improve strength and stability of the modular wall.

The present invention is a system, method and apparatus for for real-time blogging. In a preferred aspect of the invention, a real-time bi-directional blogging system can include a blog and a bi-directional syndication interface to the blog. Importantly, an instant messaging system can be coupled to the syndication interface of the blog. The instant messaging system of the present invention can include a chat server and at least one chat client. Notably, a bot can be coupled to the chat server. The bot can be programmed to communicate blog postings received in the chat server to the chat client or clients. The bot can be further programmed to communicate responses to the blog postings received from the chat client or clients to the blog through the syndication interface.
摘要:
A Branch Target Address Cache (BTAC) stores a plurality of entries, each BTAC entry associated with a block of two or more instructions that includes at least one branch instruction having been evaluated taken. The BTAC entry includes an indicator of which instruction within the associated block is a taken branch instruction. The BTAC entry also includes the Branch Target Address (BTA) of the taken branch. The block size may, but does not necessarily, correspond to the number of instructions per instruction cache line.
