Abstract: A Graphic Development Instrument System (GDIS) provides a method and capability to design, create and update display screens, including static elements (never change) and dynamic elements (change responsive to stimuli) and is able to include any controller function, without rewriting or modifyng the software. The GDIS enables a screen designer to create EPROMS for those screens for different for example vehicles or models.

Abstract: An advanced display system controller is described for use in automotive vehicles. The controller has electronic circuitry to allow it to be programmed to display monochrome or color graphics and text on an all-points-addressable display device such as a CRT or an Electro-Luminescent (EL) Flat panel. The display resolution and scan rates may be programmed differently depending on the display type and size. The vehicle operator controls the display system via a reconfigurable switch system (RSS), such as an Infrared Touch Panel or Mylar Touch Switch Matrix mounted over the face of the display. In addition, external discrete switches may also be attached to the controller. The controller includes a master microprocessor and a slave microprocessor with preferred partitioning of functions and communicates with other parts of the vehicle via two serial data communication links, a Random Access bus and a Poll/Response bus.
