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.

Conventional schedulers employ designs allocating specific processor and memory resources, such as memory for configuration data, state data, and scheduling engine processor resources for specific aspects of the scheduler, such as layers of the scheduling hierarchy, each of which consumes dedicated processor and memory resources. A generic, iterative scheduling engine, applicable to an arbitrary scheduling hierarchy structure having a variable number of hierarchy layers, receives a scheduling hierarchy structure having a predetermined number of layers, and allocates scheduling resources such as instructions and memory, according to scheduling logic, in response to design constraints and processing considerations. The resulting scheduling logic processes the scheduling hierarchy in iterative manner which allocates the available resources among the layers of the hierarchy, such that the scheduler achieves throughput requirements corresponding to enqueue and dequeue events with consideration to the number of layers in the scheduling hierarchy and the corresponding granularity of queuing.

A processing system has a processor core executing instructions of a first instruction set and an instruction translator for generating translator output signals corresponding to one or more instructions of the first instruction set so as to emulate instructions of a second instruction set. The instruction translator provides translator output signals specifying operations that are arranged so that the input variables to an instruction of the second instruction set are not changed until the final operation emulating that instruction is executed. An interrupt handler services an interrupt after execution of an operation of the instructions of the first instruction set. Arranging the translated sequences of instructions such that the input state is not altered until the final instruction is executed has the result that processing may be restarted after the interrupt either by rerunning the complete emulation if the final operation had not started when the interrupt occurred, or by running the next instruction from the second instruction set if the final operation had started when the interrupt occurred.
