Title: Innovations by Richard G VanDuren
Introduction
Richard G VanDuren is a notable inventor based in Boca Raton, FL (US). He has made significant contributions to the field of data processing systems, holding a total of 2 patents. His work primarily focuses on enhancing the efficiency and functionality of input/output controllers.
Latest Patents
One of his latest patents is titled "Peripheral attachment interface for I/O controller having cycle steal." This I/O interface allows for the attachment of a data processing system to devices that utilize different 'handshaking' protocols and bit-parallel data exchange capacities. The handshaking control circuits enable communication with devices in both pulsed and interlocked modes. Additionally, timer circuits provide various time reference signals for device transfer, while switching options associated with the timer allow for selective use of timer outputs as pulsed mode handshaking functions. The interface also includes a counter circuit and associated interface port that enable the system to count events related to device-originated pulses.
Another significant patent by VanDuren is the "Cycle stealing I/O controller with programmable offline mode of operation." This invention features a dual mode microprocessor that can function as either a front-end I/O controller processor or as a secondary data processor with independent capabilities. The host software prepares a list of device control block (DCB) arrays, which contain primary commands that the microprocessor interprets to evoke these modes. The architecture of the command list includes commands that allow the microprocessor to exchange data with the host or a device, perform arithmetic operations, and directly control the device interface.
