Title: Frank V Cassarino, Jr: Innovator in Firmware and Hardware Systems
Introduction
Frank V Cassarino, Jr. is a notable inventor based in Weston, MA (US). He has made significant contributions to the field of data processing systems, holding a total of 7 patents. His work primarily focuses on firmware and hardware systems that enhance the testing and functionality of interface logic.
Latest Patents
One of his latest patents is a firmware/hardware system for testing interface logic of a data processing system. This innovative method allows for the testing of interface logic in systems with multiple units communicating over a common electrical bus. Under firmware control, an incorrect parity is generated in a main memory address, which is then loaded into output registers of a system unit. A bus cycle request is issued, and upon the bus's availability, the system unit acknowledges the memory address to initiate data transfer. This process enables the comparison of data in output and input registers to detect any interface logic errors.
Another significant patent is the logic board interlock indication apparatus. This invention involves multiple logic boards connected over a common electrical bus using connectors. Each board includes terminals for an interlock signal wire that is daisy-chained through the boards. By providing a known signal state on the interlock signal wire, any improper connection or error condition in one of the logic boards can be indicated by a sensor located at the last logic board.
