摘要： A personal computer has two memory banks respectively connected to two parity check units operative to detect parity errors. Upon doing so, each unit feeds a parity error signal to a separate latch. The latches are connected to a logic circuit which is in turn connected to an interrupt controller that initiates an interrupt when a parity error occurs. One latch is further connected to a check bit of a register of an I/O port and the check bit is set by the one latch. An interrupt handler reads the register and provides messages indicating which memory bank caused the parity error.

摘要： Data transfer between subsystems of an information handling system employing a multiple subsystem clock environment architecture, or between multiple information handling systems operating with different clock frequencies, is synchronized using a timing aligned multiple frequency synthesizer with a synchronization window decoder. A frequency generation circuit in circuit communication with a data synchronization circuit functions to produce a synchronized timing signal(s) to permit a central processing unit operating in one subsystem clock environment to function with a peripheral subsystem(s), such as a memory controller, operating in a different subsystem clock environment, or permits information handling systems operating with different clock frequencies to function with one another. Data transfer synchronization delays are reduced and mean-time-to-failure of signal synchronization accuracy is increased by eliminating metastability effects from the synchronization circuitry.

摘要： A system for electronic imaging of a hemispheric field of view includes a camera for receiving optical images of the field of view and for producing output data corresponding to the optical images. The camera includes an optical assembly for producing images throughout a hemispheric field of view for optical conveyance to an imaging device or photographic film. The optical system assembly has lens components that selectively emphasize the peripheral content of the hemispheric field of view. An electronic imaging device within the camera or a film-to-digital date conversion system provides digitized output signals to input image memory or electronic storage devices. A transform processor selectively accesses and processes the digitized output signals from the input image memory according to user-defined criteria and stores the signals in output image memory. The signals in the output image memory can then be displayed according to the user-defined criteria.
