GRAPHIC / IMAGE PROCESSING METHOD AND DEVICE

摘要

PURPOSE: To easily execute parallel processing by arranging the pins of a smart video memory so that the memory can be accessed directly from an external element as a standard video memory element. CONSTITUTION: A program memory 12 is connected to an instruction decoder 14 and the decoder 14 outputs a control signal to a logic unit 16 when the decoder 14 decodes an instruction existing in the memory 12. The unit 16 is connected to the memory 12 and a data memory 18 and the memory 18 is directly connected to an access memory 19. A memory controller 20 is also connected to the unit 16. In an element 10, pins are arranged so that the element 10 can be accessed from an external element as a standard video memory element. The element 10 contains 40 pins and each pin is provided with an input and output which are equivalent to those of a representative VRAM.
