摘要： This disclosure describes techniques for handling divergent thread conditions in a multi-threaded processing system. In some examples, a control flow unit may obtain a control flow instruction identified by a program counter value stored in a program counter register. The control flow instruction may include a target value indicative of a target program counter value for the control flow instruction. The control flow unit may select one of the target program counter value and a minimum resume counter value as a value to load into the program counter register. The minimum resume counter value may be indicative of a smallest resume counter value from a set of one or more resume counter values associated with one or more inactive threads. Each of the one or more resume counter values may be indicative of a program counter value at which a respective inactive thread should be activated.

摘要： In a specific embodiment, a system for providing video is disclosed, the system having a system bus, which in one embodiment is an Advanced Graphics Port (AGP) bus. The system bus is connected to a data bridge, which is connected to a second and third AGP bus. Each of the AGP busses are connected to graphics processors. The bridge routes data requests from one graphics processor to the second graphics processor without accessing the system AGP bus based upon a memory mapping information stored in a routing table or a register set. In another aspect of the present invention, the bridge responds to initialization requests using attributes that may vary depending on the specific mode of operation. Another aspect of the present invention allows for conversion between various AGP protocol portions.

摘要： A method and apparatus for storing sequential data words associated with a block of data in a non-linear manner within the data block is taught such that any row or column associated with the data block may be accessed using a burst access. A row, or column of data accessed by a burst frees up instruction bandwidth of a video controller. In particular, it is assured that each row and column of data associated with the data block has at least one sequential pair of data words associated with it. By assuring at least one sequential pair of data words, it is possible to issue a burst request for a minimum of two words of data with each row access, or column access of the video controller.

摘要： A method and apparatus includes a real time event engine that monitors event signals. A real time event detector within the real time event engine detects when the real time event occurs. Thereupon, real time event commands within a real time event command buffer are fetched and consumed by the command processor in response to the occurrence of the real time event. The real time event detector contains a plurality of control registers, which contain an event selector register, a real time command buffer point register, and a real time command buffer length register. A driver may program the registers, whereupon a singe real time event detector may be used in conjunction with a plurality of real time event command buffers.
