    摘要: A monitor interface cable for transmitting display data and command data between a computer system and a display monitor preferably including a microcontroller. The monitor interface cable enables both display and command data to be transmitted simultaneously from the computer system to the display monitor. Inside the computer system, data containing the commands written to a particular memory location in a video buffer card is applied to various signal lines located in the monitor interface cable. These signal lines are coupled to the microcontroller located in the display monitor which receives the commands and performs various controlling functions in response. Status information in the form of a command is transmitted back across a second signal line to the computer system where various software programs including drivers receive and process the status information. Display data is simultaneously transmitted over other signal lines also located in the monitor interface cable.

    摘要: A bus architecture and protocol for integrated data and video memory. A high speed dedicated memory bus is coupled to a memory controller. The memory controller is in turn coupled to a multiple processor bus interconnecting one or more processors. Single in-line memory modules (SIMMs) incorporating dynamic random access memory (DRAM), video RAM (VRAM), and static nonvolatile RAM (SRAM) are coupled to the memory bus. Bus control signals forming a bus protocol, and address and data lines from the memory controller are shared by all memory modules operating on the memory bus. Certain control signals invoke specific operations on memory modules or are ignored, depending on the type of memory module receiving the control signal. The memory modules incorporate the consistent protocol by virtue of a consistent control signal pin out. The SIMMs further incorporate buffering and conversion functions, thereby relieving the memory controller of service overhead associated with these functions. Integrating all forms of memory into a single data and video memory architecture permits a highly functional dedicated memory bus to be connected to the computer system.
