Abstract: A processor includes logic for attaining a very fast exception handling functionality while executing non-threaded programs by invoking a multithreaded-type functionality in response to an exception condition. The processor, while operating in multithreaded conditions or while executing non-threaded programs, progresses through multiple machine states during execution. The very fast exception handling logic includes connection of an exception signal line to thread select logic, causing an exception signal to evoke a switch in thread and machine state. The switch in thread and machine state causes the processor to enter and to exit the exception handler immediately, without waiting to drain the pipeline or queues and without the inherent timing penalty of the operating system's software saving and restoring of registers.

Abstract: A circuit and method are provided for calibrating an analog oscillator in the digital domain. The circuit and method disclosed herein centers an oscillation frequency of an analog oscillator by producing a binary signal to which the analog oscillator is responsive. Changes in the binary digital signal cause the oscillation frequency of the analog oscillator to shift in a desired direction to calibrate the analog oscillator. At the completion of the calibration process, the control of the oscillation frequency of the analog oscillator is switched to the analog domain so that the analog oscillator is responsive to an analog control voltage to shift the oscillation frequency.

Abstract: A method for conditionally sharing dynamically compiled code between different class loaders is provided. In this method, bytecodes of a first class type are compiled into a compiled code if the bytecodes have not been compiled. The locations of sequence of instructions in the compiled code that are loader dependent are then recorded. Thereafter, the loader dependencies in the compiled code are compared to determine whether the compiled code can be used by a method of a second class type. If the loader dependencies of the second class type are different from the loader dependencies of the first class type, the compiled code for the method of the first class type is cloned. Subsequently, portions of the cloned code that are loader dependent are modified to enable the method of the second class type to use the cloned code.

Abstract: A cluster of multiprocessing nodes uses snooping-based cache-coherence to maintain consistency among the cache memories of the multiprocessing nodes. One or more of the multiprocessing nodes each maintain a directory table that includes a list of addresses of data last transferred by cache-to-cache transfer transactions. Thus, upon a local cache miss for requested data, a multiprocessing node searches its directory table for an address of the requested data, and if the address is found in the directory table, the multiprocessing node obtains a copy of the requested data from the last destination of the requested data as indicated in the directory table. Thereafter, a message indicating the completion of a cache-to-cache transfer is broadcast to other connected multiprocessing nodes on a “best efforts” basis in which messages are relayed from multiprocessing node to multiprocessing node using low priority status and/or otherwise unused cycles.
