TVP3010-85

The TVP3010-85 palette is an advanced Video Interface Palette (VIP) from Texas Instruments implemented in the EPICE 0.8-micron CMOS process. Maximum flexibility is provided by the pixel multiplexing scheme.The scheme accommodates 64-, 32-, 16-, 8-, and 4-bit pixel buses without any circuit modification. This enables the system to be easily reconfigured for varying amounts of available video RAM. The device supports selection of little- or big-endian data format for the pixel-bus/frame-buffer interface. Data can be split into 1, 2, 4, or 8 bit planes for pseudo-color mode or split into 12-, 16- or 24-bit true-color and direct-color modes. For the 24-bit direct color modes, an 8-bit overlay plane is available. The 16-bit direct- and true-color modes can be configured to IBM XGA) (5, 6, 5), TARGA) (5, 5, 5, 1), or (6, 6, 4) as another existing format.An additional 12-bit mode (4, 4, 4, 4) is supported with 4 bits for each color and overlay. An on-chip, IBM XGA-compatible hardware cursor is incorporated so that further increases in graphics system performance are possible. The TVP3010-85 device is also software compatible with the IMSG176/8 and Bt476/8 color palettes.

The features of TVP3010-85 are:(1)second-generation video interface palette;(2)supports system resolutions of:1600×1280×1,2,4,8,16 bits/pixel @ 60-Hz refresh rate;(3)RCLK/SCLK/LCLK data latching mechanism allows flexible control of VRAM timing;(4)direct interfacing to video RAM;(5)support for split shift-register transfers;(6)64-Bit-wide pixel bus;(7)supports overscan for creation of Custom screen borders;(8)windowed overlay and VGA capability;(9)color-keyed switching of direct color and overlay;(10)internal frequency doubler.
