Words that you must replace with actual values appear in italics (for example, user-name might have an actual value of j oe). Key names appear in CAPS (for example, RETURN). Special terms are in bold type when they are introduced; many of these terms are also defined in the glossary in AJUX System Overview. Syntax notation All A/UX manuals use the following conventions to represent command syntax. A typical A/UX command has the form command r.flag-option] [argument] ... where: command is a command name (the name of an executable file). flag-option represents one or more flag options. Historically, flag options have the form -[opt ... ] where opt is a letter representing an option. The form of flag options varies from program to program. Note that with respect to flag options, the notation [-a][-b][-c] means you can select one or more letters from the list enclosed in brackets. If you select more than one letter, you use only one hyphen, for example, -ab. argu…

RasterOps RGS14188 User's Guide Preliminary REVISION XA 1 11/2/90 JEFF TINGLEY CONFIDENTIAL THIS DOCUMENT IS THE PROPERTY OF RasterOps REPRODUCllON OF THIS · DOCUMENT IS PROHIBITED . November 2, 1990 RGS14188 User's Guide 1.0 Introduction The RGS14188 Frame Buffer Controller (FBC) is a high-performance CMOS device that controls the video display and dynamic memory of a bit-mapped graphics system. Although the RGS14188 was designed to provide control of varying size, multi-port DRAMs (VRAMs) it works equally well with standard DRAMS and is easily interfaced to a variety of CPUs and buses. The principal role of an FBC is to provide an external processor with virtually unlimited access to (video) memory. It eliminates the delays and overhead caused by display update address generation, reloading shift registers, and DRAM refresh. Furthermore, the FBC reduces the amount of hardware needed to interface a RAM array and provides the user with the utmost flexibility. Highly programmable, the RGS14188 supports a broad range of raster-scan display systems with various resolutions and scan rates. Some of the major functions for RGS14188 FBC are: Generates all control signals necessary to control 256K, 1, 2, and 4 Megabyte VRAM devices, as well as those necessary to control conventional DRAMs of the same sizes. Generates the video synchronization and blanking signals necessary to control a CRT monitor. Accommodates processor data paths of arbitrary widths, working equally well with 8-bit to n-bit processors or bus architectures. Supports both interlaced and non-interlaced displays of essentially any display resolution. Automatically generates the special display-update cycles required by VRAM memories to maintain the CRT display. Automatically performs periodic RAM refresh cycles necessary to maintain the data stored. The block Diagram of a typical system using the RGS14188 is shown in Figure 1-1. 2 RGS14188 User's Guide November 2, 1990 CRT Control Signals RasterOps BGS14188 Host Bus Address Bus DRAM VRAM ROM Video Back End DAC Red Green Blue Data Bus Pixel Clock Figure 1-1 Typical System Using the RGS14188 2.0 Pinout and Signal Descriptions A functional drawing of the RGS14188 is given in Figure 2-1 and the pin number assignments are given in Figure 2-2.

The slot is coupled to the 32-bit address bus, being substantially a NUBUS bus, and the slot includes distinct identification line means which provide the slot with an identification number (distinct number) in the computer system. The card includes a decoder means which is coupled to the slot to receive the identification number; the decoder means has nem ory reservation means which causes 256 megabytes of memory space to be reserved for the card in the slot, such that, where the slot number is X, the 256 mega bytes of reserved memory space begins at location SX000 0000 and ends at locations SXFFFFFFF. 10 Claims, 7 Drawing Sheets U.S. Patent Feb. 27, 1990 Sheet 1 of 7 4,905,182 5 . ...
