Abstract: Method and apparatus for use in a digital data processing system that evaluates functional networks. A method operates to assign a unique signature to each input constant of the network, assign a unique signature to each output of a network Function, and to store each of the constants and function outputs along with their assigned signatures. The signatures operate as an access key to the associated stored constants and function outputs, thereby eliminating a requirement to reevaluate a Function if its outputs already exist. A storage element, or Dictionary (20), stores data units, such as input data, intermediate values, and/or pointers to same, each with a unique signature. The storage element, in concert with a Dictionary Controller (18), provides for the deletion of a stored data unit that is associated with a specified signature and the retrieval of a stored data unit that is associated with a specified signature. Preferably, the signatures are generated from a combination of constant and Function attributes and values and are each uniquely encoded by a CRC generator (14).

Abstract: A multi-mode terminal system utilizes a single embedded processor (14) and a single RAM (12) for performing modem operations, graphics/video processing and general purpose control tasks. The display lists, frame buffer, font area, and embedded processor memory are located in the same single random access memory, thus allowing the use of a single RAM for DSP data, display lists, video buffers, voice compression/decompression algorithms and embedded controller tasks. The system is adaptable for programming the desired video standard, modem type and display list format. Since both the video function and the embedded processor are supported by the same RAM, a RAM arbiter (18) resolves bus contention.

Abstract: A linear compensating circuit is provided which comprises a first level detection circuit for detecting the level of an input signal to an amplifier, a second level detection circuit for detecting the level of an output signal from the amplifier, an amplitude compensating circuit for controlling the amplitude of the input signal in accordance with the difference between the signal level detected by the first detection circuit and the signal level detected by the second level detection circuit for improving the linearity of an input-output characteristic of the amplifier, and a phase compensating circuit for controlling the phase of the input signal in accordance with the signal level detected by the second detection circuit. This linear compensating circuit performs the compensations of amplitude and phase and as a result, the degradation of phase characteristic induced due to the compensation of amplitude can be prevented, resulting in a reduction in the distortion of an output signal of the amplifier even when it is being operated in the vicinity of the saturation range. This linear compensating circuit is effective when applied to a power amplifier, particularly to a high frequency power amplifier. It has a characteristic set preferably to cancel the phase change of the output signal induced caused by the compensation of amplitude by the amplitude compensating circuit.

Abstract: A transaction description database represents long running computations as a set of computational steps with data flows therebetween. The description database defines each step's input and output signals, input condition criteria for creating an instance of the step, an application program associated with the step, and criteria for selecting a resource to execute the step. A flow controller controls the process of executing instances of each defined type of long running transaction. Execution of a long running transaction begins when a corresponding set of externally generated input event signals are received by the flow controller. During execution of a long running transaction, each step of the transaction is instantiated only when a sufficient set of input signals is received to execute that step. At that point an instance of the required type of step is created and then executed by a selected resource. After termination of a step, output signals from the step are converted into input event signals for other steps in the long running transaction in accordance with data stored in the transaction description database. Each step executes an application program and is treated as an individual computation insofar as durable storage of its computational results. Log records are durably stored upon instantiation, execution and termination of each step of a long running transaction, and output event signals are also logged, thereby durably storing sufficient data to recover a long running transaction with virtually no loss of the work that was accomplished prior to a system failure.

Abstract: A list data structure is provided within a Structured External Storage (SES) processor attached to one or more processors. Applications executing on the processors share data within the list data structure, and are provided mechanisms for conditionally executing commands at the SES. The conditional operation of complex data object operations is based upon an atomically executed predicate operation which verifies the presumed state of the data object before allowing any further data object manipulation. Modification of state information may also be atomically performed. The SES operations are initiated by a command sent as a message across the processor-SES interface.

Abstract: A method for serialising access to computer system resources without disabling interrupts in critical code sections or requiring excessive use of spin locks. A queue lock is introduced that allows an interrupt process to enqueue and be processed in turn without a spin lock and to block process code access to a particular resource until all interrupts are processed. Process level code is blocked from accessing a locked resource while requests for accesses from interrupt level code are queued in a deferred work queue which is processed prior to the release of the blocking lock. Establishment of deferred work queue means that processing can continue without disablement of interrupts and without significant overhead consumed by processes holding spin locks.

Abstract: A loudspeaker unit for producing wide dispersion sound for use in wide imaging stereo has a plastics case defined by a front 10 onto which a separate sound mirror 18 fits, and a back 12. A drive unit 16 fits into a housing 24 located opposite to the sound mirror 18. A frame 14 of metal or other rigid material provides a mechanical connection between the drive unit 16 and a load-bearing plinth 20 on which the sound mirror 18 is supported. The case front and back 10, 12 together define an upper space 62 behind drive unit 16 that is connected to a lower space 60 beneath the sound mirror 18 by a passage 64 behind wall 22 of the case front 10. The three spaces 60.62,64 provide a combined volume of gas that provides a reflex load for the drive unit 10. The overall size of the unit can be reduced without corresponding loss of bass frequency response, and, because the sound mirror 18 is separate from the plinth 20, a range of drive units 16 of different dispersion patterns can be provided, requiring only alteration in the surface profile of the sound mirror 18.
