    Abstract: A peripheral resource controller such as a caching disk array controller is provided for controlling the transfer of data between a host bus and a peripheral resource, such as an array of hard disk drives. The peripheral resource controller includes a bus interface controller for providing an interface between the host bus and a local bus of the peripheral controller. The bus interface controller further includes a peripheral bus interface which accommodates accesses to a peripheral bus and a DMA controller for controlling direct memory access operations between a local memory of the peripheral controller and a system memory of the host computer. A DMA transfer list memory is coupled to the peripheral bus for storing DMA transfer information. The DMA controller fetches host and local address as well as block size information from the DMA transfer list memory to thereby effectuate DMA operations. In one specific implementation, a local processor of the peripheral controller loads the DMA transfer information into the DMA transfer list memory by causing the execution of one or more memory write cycles on the local bus. A local bus interface of the bus interface controller responds as a target and routes the data to a peripheral bus interface. The peripheral bus interface, which functions as a master of the peripheral bus, responsively effectuates corresponding cycles on the peripheral bus to write the DMA transfer information into the DMA transfer list memory.

    Abstract: A digital data storage system which does not require the use of moving, mechanical components, and which utilizes semiconductor memory elements. In one embodiment, the digital data storage system includes a ROM, a system control microcomputer, a digital signal processor (DSP), and a D/A converter. In operation, the DSP is responsive to control signals generated by the system control microcomputer for reading out digital data, e.g., digital audio data, stored in the ROM, and decoding the read-out digital data. The D/A converter functions to convert the decoded read-out digital data into an analog output signal, e.g., an analog audio signal, and to supply the analog output signal to an output terminal. The digital data storage system of this embodiment is a playback-only system. In another embodiment, the digital data storage system includes all of the elements of the above-described embodiment, and further includes an A/D converter and an EEPROM, to facilitate the recording of digital data. In operation, during a record mode of operation, the A/D converter functions to convert an input analog signal, e.g., an analog audio signal, into an input digital data signal, and the DSP functions, in response to the control signals, to write the input digital data signal into the EEPROM. The digital data storage device of this embodiment functions as a record/playback system.

    Abstract: Control of a plurality of relay drivers by smart control devices and the continuous status monitoring of a plurality of switches and associated smart sensors, wherein each smart control device and each smart sensor is connected at a separate single point on a single-wire bus, are affected by a smart control and sensor device multiplex system. The system employs a microcomputer and a driver and receiver circuit for developing a particular offset square wave pulse train which is placed on the bus to provide power and control voltage signals to the plurality of smart control devices and smart sensors. The smart control devices contain circuits that respond to the wave form in a manner that causes each smart control device to drive an associated relay driver after a chosen number of polling cycles. Current signals are sent over the bus back to the driver and receiver indicative of the status of the smart control device. The smart sensors contain cirucits that respond to the waveform in a manner that causes each smart sensor to send current signals back over the single wire bus to the driver and receiver circuit and then on to the microcomputer during designated repetitive and sequential time slots. The driver and receiver circuit receives, interprets and converts the current signals from the smart control devices and the smart sensor into voltage signals used by the microcomputer for establishing a history of the status of the bus, the control devices, the sensors and the switches. The microcomputer supplies continuous and updated information to a display system indicative of the status of each control device and each sensor and its assoicated switch.
