Abstract: A reconfigurable signal processing device that includes a plurality of programmable modules that are reconfigurable to perform one of a plurality of selected signal processing functions. The modules may be reconfigured under software control to act as one of a time base generator, a counter, an accumulator, an address register, a delay circuit, and a timer. The plurality of modules are selectively reconfigured and selectably interconnected by a configuration and control circuit that receives command signals from the host processor containing the control software. The device further includes a plurality of input channels for receiving and initially processing analog signals to be tested and a high speed memory for storing data as required for the selected signal processing device. The devices that can be formed by configuring and interconnecting the programmable modules are for example, a counter/timer, an arbitrary function generator, a pluse generator, and a digitizer.

Abstract: A color graphics display terminal having an edit mode of operation and a graphic mode of operation is disclosed. The edit mode provides interactive man-machine interface capability with an external digital computer, such as an automatic test system control computer. When operating in the graphic mode it decodes received instructions to produce a multi-colored visual display on a raster scan cathode ray tube color monitor. Independent point addressable memories are provided for storing the information to be displayed in the two operating modes. Consequently, the information transmitted to the terminal for display in the graphic mode is saved when the terminal is switched into the edit mode and vice versa. A key feature is that programs can be edited without destroying the last graphic image produced by the program being edited. Data and control commands (such as mode change) are entered into the terminal via a keyboard.
