Title: The Innovations of Phillip W. Marsh
Introduction
Phillip W. Marsh is a notable inventor based in Granger, Utah, who has made significant contributions to the field of data processing systems. With a total of two patents to his name, Marsh has developed innovative solutions that enhance the efficiency and reliability of data handling.
Latest Patents
Marsh's latest patents include a "Buffer Memory Arrangement" and an "Error Detection System." The Buffer Memory Arrangement is designed for use in conjunction with a controller and multiple peripheral units or subsystems of a data processing system. This arrangement features a dynamic RAM buffer memory that receives and stores information from peripheral units, while also supplying stored information back to these units. It includes an address pointer memory that identifies locations in the buffer memory for reading or storing information, along with an encoder that responds to request signals from peripheral units to supply identity signals to the address pointer memory.
The Error Detection System involves a redundant logic unit that operates alongside a required logic unit. Both units produce output data that is expected to be identical. The output from the required logic unit is sent to a data bus, while the redundant logic unit's output is directed to a parity check digit generator. This generator creates a parity check digit that is applied to the data bus along with the required logic unit's data. A parity checking circuit then verifies the correctness of the parity, producing an alarm signal if discrepancies are detected.
