TVP3010-135MGAB

视频接口调色板 Video Interface Palette

Introduction

The TVP3010C and the TVP3010M palettes are commercial and military versions, respectively, of an advanced Video Interface Palette VIP from Texas Instruments implemented in the EPIC 0.8-micron CMOS process. Differences between the two versions are outlined in separate tables. In both versions, 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-color 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. Both devices are software compatible with the INMOS IMSG176/8 and Brooktree Bt476/8 color palettes.
