摘要： A data processing system and method for arranging and accessing information that crosses cache lines utilize dual cache columns. The dual cache columns are formed of two access-related cache lines. The two cache columns contain sequential information that is stored in cache lines in a sequential and alternating format. A processor makes a request for a particular instruction. An instruction fetch unit takes the instruction request and creates a second instruction request in addition to the first instruction request. The two instruction requests are sent simultaneously to first and second content addressable memories (CAMs) respectively associated with the first and second cache columns. The CAMs are simultaneously searched and any cache hits are forwarded to a switch. The switch combines the relevant portions of the two cache lines and delivers the desired instruction to a processor. A method of accessing and distributing stored data in a computer system is also described. The method includes generating the data to be distributed by combining relevant segments from simultaneously accessed first and second cache lines.

摘要： A method for detecting bypass error conditions in a load/store unit of a superscalar processor includes determining whether a load instruction has executed out-of-order with respect to an executing store instruction when a real address to a word boundary of the load instruction and a real address to a word boundary of the executing store instruction match, and identifying a bypass error condition for the load instruction when the load instruction has executed out-of-order with respect to the executing store instruction. In a system aspect, the system includes a load queue, detection logic, and completion logic. The load queue includes a real page number buffer for storing a real address to a word boundary for each executed load instruction. The detection logic compares real addresses to a word boundary for a load instruction against an executing store instruction and compares a program order of the load instruction and the executing store instruction when the real addresses to a word boundary match. The completion logic receives the executing store instruction and a bypass error signal when the load instruction has executed out-of-order with respect to the executing store instruction. The completion logic also receives the identifier of the load instruction which bypassed the executing store instruction.

摘要： A system and method to provide haptic and visual feedback of motion of the skier foot and the forces transmitted to the skiboot insole and consequently to the ski/snow interface. This system comprises a motion and force sensors and a haptic actuator embedded in the skiboot insole in communication with a smart-phone based analysis application, configured to calculate insole motion and orientation and the distribution of pressure points inside the skiboot, then to provide haptic feedback to the skier foot instructing on timing and direction of change in the pressure points necessary to achieve optimal turn parameters. Furthermore, analyzed together with GPS coordinates are transmitted by the application to the cloud based server for further processing. Graphical and numerical representation of data is superimposed over a 3D map of a slope which may be viewed on the user smart-phone or on a remote computer terminal.

摘要： Prefetching data to a low level memory of a computer system is accomplished utilizing an instruction location indicator related to an upcoming instruction to identify a next data prefetch indicator and then utilizing the next data prefetch indicator to locate the corresponding prefetch data within the memory of the computer system. The prefetch data is located so that the prefetch data can be transferred to a primary cache where the data can be quickly fetched by a processor when the upcoming instruction is executed. The next data prefetch indicator is generated by carrying out the addressing mode function that is embedded in an instruction only when the addressing mode of the instruction is a deterministic addressing mode such as a sequential. The next data prefetch indicator, preferably in the form of an effective address, is identified by the instruction location indicator, preferably in the form of a program counter, by relating calculated next effective addresses to corresponding program counter tags in a searchable table.
