Latest Patents

Jan S Hermam holds a patent for a "Control sequencer with dual microprogram counters for microdiagnostics." This invention features a microprogrammed control unit that utilizes dual microprogram counters to perform microdiagnostics concurrently with macroprogram operations. The microdiagnostics include background and operability tests, which are interleaved with macroinstruction operations. The design allows background tests to run during processor idle time, while operability tests are executed at processor turn-on. The hierarchical organization of microdiagnostics enables the same microprogrammed test module to be used for both types of tests. Additionally, a prediction/residual coding technique is employed for fault detection in address and data information within the control sequencer.
