Title: Character string drawing system
Inventor: SAITO MASATO
IPC: G09G5/26
Filed: 1990-05-09
Abstract: PURPOSE:To reduce the arithmetic load on a host computer and to speed up arithmetic operation and character string drawing by performing font conversion and segment switching by a display processor. CONSTITUTION:The display processor converts font coordinates indicating a character into physical coordinates with a font conversion matrix and a segment conversion matrix. Namely, the font coordinates are multiplied by the font conversion matrix to perform the segment conversion first and thus converted into logical coordinates. Then the logical coordinates are multiplied by the segment conversion matrix to perform the segment conversion. The physical coordinates are developed in the physical coordinate space of a frame buffer 14 and the character is displayed on the screen of a display 18. Consequently, arithmetic regarding character string drawing is simplified to reduce the arithmetic load on the host computer 16 and an overhead regarding data transfer, etc., is reduced to shorten the drawing time.
