- Functional Description
- The 12065A Video Output Interface provides full-color video output
- capability to color displays for the HP 1000 A-Series family of computer
- products. The 12065A has been designed to specifically address the needs
- of the computer-aided manufacturing marketplace. This video interface
- offers medium resolution, as well as some unique display features that
- will dramatically increase your productivity.
- The card utilizes a Motorola 68008 16-bit microprocessor for system
- control and backplane communications. It also provides supervisory
- control over a specialized graphics processor, pixel memory and video
- circuits. Four pixel memory planes provide for two combinations of color
- and character capability. In one mode, three pixel memory planes are
- used to produce 8 colors from a palette of 4096 leaving the fourth plane
- for overlay of characters, cursors, and prompts. In the second color
- mode, all four planes are used to produce 16 colors from a palette of
- 4096. In both modes, independent blink control of each color is possible
- on-card.
- A standard character set is provided in ROM with user-specified size
- and orientation for maximum flexibility. In addition, the card will
- support user-defined characters, for example, foreign languages which
- can be downloaded to local RAM from the A-Series CPU.
- Benefits of the on-card intelligence and the DMA per I/O card
- A-Series architecture result in flexible drawing capabilities. In an
- Update mode, an existing screen is added to, either with characters or
- vectors, with immediate display of results. This is the mode you would
- use to change data or to perform limited animation, such as increasing
- or decreasing tank levels in a process control flow application.
- Using the Frame Buffer Read/Write capability, entire screens can be
- downloaded via DMA to pixel display memory (frame buffer) and then to
- the screen. The whole screen image is displayed within seconds. This
- feature is particularly useful in applications where several displays
- are used frequently as operators execute sequences of control or
- trackdown process problems tagged with alarms. Frame Buffer Reads/Writes
- automatically take advantage of flash-fill, where data is written to
- display memory while the screen is continuously blanked. The screen is
- then unblanked to display the image. Update mode can also be configured
- for flash-fill to take advantage of the higher performance realized.

-
- In general, display images used frequently will be initially created in
- Update mode. Once in frame buffer memory, the image will be stored in
- A-Series memory, or on disk, via Frame Buffer Reads. Later, the
- A-Series can redisplay the image using Frame Buffer Writes; additional
- modifications can be made in Update mode.
- Finally, the 12065A also supports two RS-232-C serial ports to allow
- for the direct attachment of graphics input accessories. This allows
- devices like custom keyboards and keypads, touch screens, trackballs,
- joy sticks, or mice to be interfaced through one graphics sub-system.
- This saves money and I/O slots.
