A color synchronizer and windowing system for use in a video or video/graphics system which uses digital television technology integrated circuits to digitize the video information. The digitized video information is stored in a frame buffer as luminance and chrominance data samples. The frame buffer also stores a chrominance reference synchronization signal which is synchronized to the digitized chrominance data samples so as to properly identify the boundary for each chrominance data sample; wherein each such chrominance data sample is associated with a plurality of luminance data samples. This encoded data insures that the luminance and chrominance data samples are properly decoded on chrominance data sample boundaries even though the synchronization signal normally associated with the digital television technology integrated circuits is not available due to the storage of the luminance and chrominance data samples within the frame buffer. In this manner the digitized video information may be reconfigured or combined with graphic information in any desired fashion without loosing chrominance synchronization. The color synchronizer and windowing system for use in a video/graphics system provides a definition for windows and viewports which minimizes the amount of memory necessary to define windows and viewports as well as to be able to present such information to an associated display monitor on a real-time basis.

Data to be stored in a frame buffer (12) that stores data representing an image are drawn from a look-up table (34). The look-up table (34) contains conversion data and is addressed by the output of a multiplexer circuit (24). The multiplexer circuit (24) receives its inputs from the data output port of the frame buffer (12), from a register (42), and from an analog-to-digital converter (22) that converts the output of a video camera (20) to digital signals. In response to different values on selection-signal lines (36), the multiplexer circuit (24) assembles the address that it applies to the look-up table (34) from different combinations of the outputs of the frame buffer (12), the register (42), and the analog-to-digital-converter (22). By changing the selection signals applied to the multiplexer circuit (24), it is possible to employ the same image-processing system (10) to perform different functions, such as gamma correction, contrast variation, iamge-from-image subtraction, and multiple-image averaging.

An improved programmable controller having the ability to use two different data bases while presenting to the outside world a uniform word size. The programmable controller includes pipeline processing and hardware solution of a user control program in a network node format. A memory management scheme is provided allowing for the direct addressability of one-half million words by utilization of a page register. The programmable controller can be incorporated into a network containing other programmable controllers. The programmable controller also incorporates a multi-task interrupt so that the processor can handle more than one job at any particular time. Input/output tasks are handled logically in the scan solving the user networks rather than being based upon a particular physical area of the controller memory.

A small, low cost, programmable controller is described capable of solving user programs represented in networks having up to seven rows and eleven columns. A column solver is utilized to provide efficient and fast solution of the user control network. The programmable controller also solves calculate functions having multiple outputs to facilitate use of the output information in the control program. A programming panel using a CRT display shows one or more selected control networks and, in conjunction with the central processing unit of the programmable controller, provides for the insertion of networks between two existing networks. Since the networks are solved by the controller mainframe in a sequential fashion, this network insertion allows the user to optimize his or her control program when solution order of the networks is important. The output coil numbers of network rows may also be assigned by the user independent of their placement in the control program to further facilitate programming the controller. The programming panel includes a movable cursor on the CRT display which, in conjunction with a light-emitting diode (LED), allows the user to monitor the real-time power flow at any particular point in the displayed ladder diagram network.
