Abstract: A software-driven multiprocessor emulation system comprising a plurality of emulation processors connected in parallel in a module. One or more modules of processors comprise an emulation system. An execution unit in each processor includes a table-lookup unit for emulating any type of logic gate function. A parallel bus connects an output of each processor to a multiplexor input with every other processor in a module. Each processor embeds a control store to store software logic-representing signals for controlling operations of each processor. Also a data store is embedded in each processor to receive data generated under control of the software signals in the control store. The parallel processors on each module have a module input and a module output from each processor. The plurality of modules have their module outputs inter-connected to module inputs of all other modules. A sequencer synchronously cycles the processors through mini-cycles on all modules.

Abstract: The present invention is a device to measure and display digitally the automotive engine parameters RPM (rotations per minute), dwell, and points resistance. The general approach taken is to establish a signal with a current controlled oscillator whose frequency is proportional to the above engine parameters. This signal is then processed by a digital counter whose count interval characteristics are determined by the number of cylinders in the automobile engine. The contents of the counter are converted to a digital format and displayed as an accurate representation of the parameters to be measured.
