The Thomson EF936x series is a type of Graphic Display Processor (GDP) by Thomson-EFCIS.[1] The chip could draw at 1 million pixels per second, which was relatively advanced for the time of its release (1982 or earlier).

There are various versions of the chip (EF9364,[2][3][4][5][6][7] EF9365,[8][9][10] EF9366,[11][12][10] EF9367,[13][14][15] SFF96364,[16][17][18] EF9369[19][20][21]),[22] with slightly different capabilities.

In 1982 Commodore released a "High Resolution Graphics" board for the PET based on the EF9365 and EF9366 chips, allowing it to display 512 × 512 or 512 × 256 resolution graphics.[23][24][25] The EF9366 was also used on the SMP-E353 graphic card for the Siemens SICOMP [de] computer series and on the NDR-Klein-Computer introduced in 1984.[26]

Version EF9369 was used on computers such as the Thomson MO5NR[27], MO6[28], TO8,[29] TO9[30] and TO9+,[31] and from 1985 to 1989 on the DAI Personal Computer.

Versions[edit]

Based on the 1989 data book published by the company, the EF936x series was split into Graphics Controllers and Color Palette models.[32]

Graphics Controllers

  • EF9364 CRT Processor introduced in 1981
  • EF9365 512 × 512 (interlaced), 256 × 256, 128 × 128, 64 × 64; 50 Hz[33][34]
  • EF9366 512 × 256 (non-interlaced); 50/60 Hz[33]
  • EF9367 1024 × 512 (interlaced), 1024 × 416 (interlaced); 50/60 Hz (capable of SECAM system output for the French market).[35]
  • SFF96364[36][37][38]

Color Palette

  • EF9369 - 4-bit DACs (16 out of 4096 colors - 12-bit RGB), generating gamma corrected (gamma 2.8) voltages.[21]
  • TS9370 - 4-bit DACs (16 out of 4096 colors)[39]

Capabilities[edit]

  • Integrated DRAM controller
  • Line drawing, with delta-x and delta-y limited to 255 each. Support for solid, dotted, dashed and dotted/dashed lines.[9]
  • Built-in 5 × 8 pixel ASCII font.[40] Support for rendering tilted characters, and scaling by integer factors (no antialiasing)[33]

The GPUs did not support direct access to the graphics memory, although a special command was provided to aid in implementing access to individual memory words.
