Video Interface Palette

The TVP3025 is an advanced Video Interface palette (VIP) from Texas Instruments implemented in EPIC 0.8-micron CMOS process. The TVP3025 is a superset of the 64-bit TVP3020 VIP with the addition of Brooktree BT485 Register map emulation and frequency synthesis Phase locked loops (PLLs). The BT485 Register emulation mode allows the device to be software compatible with many graphics controllers, including the S3 Vision964 and 86C928 VRAM based graphics accelerators. This new 64-bit device provides an effective migration path from lower performance graphics systems which utilize previous generation 32-bit color palettes. The TVP3025 is a functional superset of the TVP3020 and features the same 64-bit programmable pixel bus 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. All color modes support selection of little or big endian data format for the pixel bus. Additionally, the device is also software compatible with the IMSG176/8 and Bt476/8 color palettes. The TVP3025 has three 256-by-8 color lookup tables with triple 8-bit Video digital-to-analog converters (DACs) capable of directly driving a doubly terminated 75- line. The lookup tables are designed with a dual-ported RAM architecture that enables ultra-high speed operation. Sync generation is incorporated on the green output channel. Horizontal sync and vertical sync are fed through the device and optionally inverted to indicate screen resolution to the monitor. A palette-page Register is available to provide the additional bits of palette address when 1, 2, or 4 bit planes are used. This allows the screen colors to be changed with only one Microprocessor Interface unit (MPU) write cycle. By Texas Instruments
