A malware detection system seeking to identify computer viruses, worms, Trojans, banned files and the like acts to determine from the file name, file size and storage location of a computer file being tested, whether that computer file potentially matches a specific known malware free computer file stored within a list of such specific known malware free computer files. If a match occurs indicating that the candidate computer file is potentially the specific known malware free computer file, then this is confirmed by calculating a checksum of the candidate computer file and comparing this against a stored corresponding checksum of the specific known malware free computer file. If these checksums match, then the candidate computer file can be passed as clean without requiring further time consuming malware detection scanning.

A motion analysis method includes calculating a change in an amount of inertia of a region attached with an inertial sensor during a swing using an output of the inertial sensor, and identifying a maximum value of the amount of inertia during the swing to compare the maximum value and the amount of inertia at an impact with each other. A deceleration timing during the swing of the region (the grip of the sporting equipment) attached with the inertial sensor is identified, and the quality of the swing can be evaluated.

A microprocessor architecture including a predictive pre-fetch XY memory pipeline in parallel to the processor's pipeline for processing compound instructions with enhanced processor performance through predictive prefetch techniques. Instruction operands are predictively prefetched from X and Y based on the historical use of operands in instructions that target X and Y memory. After the compound instruction is decoded in the pipeline, the pre-fetched operand pointer, address and data is reconciled with the operands contained in the actual instruction. If the actual data has been pre-fetched, it is passed to the appropriate execute unit in the execute stage of the processor pipeline. As a result, if the prediction is correct, the data to use for access can be selected and the data selected fed to the execution stage without any addition processor overhead. This pre-fetch mechanism avoids the need to slow down the clock speed of the processor or insert stalls for each compound instruction when using XY memory.

The invention provides an anti-plug-in online game system. A package capturing server receives mirror image traffic transmitted by an operation switch after using a switch to perform traffic mirroring copy to network traffic between each client and a game server, and rectifies the mirror image traffic so as to obtain continuous data flow, and an analysis server receives and analyzes the continuous data flow transmitted by the package capturing server so as to determine an abnormal user, and returns the analysis result to the game server. Because the abnormal user is determined by the analysis server which is independent of the game server and the client, the influence to the operating speed of the game server itself is avoided while determining the abnormal user, thereby enhancing the game user experience.
