Block Diagram
CPU interface
This circuit is a general-purpose 8-bit CPU interface. The operating mode and other aspects are set by accessing the
interface registers and the parameter registers.
Sequence controller
Controls the functional blocks in the IC according to the encoding or decoding algorithm being used.
Encoder
Generates the codes in the various modes by recognizing inflection points in the image data. Encoded data is passed to
the data bus through an 8-bit 4-word encoding FIFO (EFIFO).
Decoder
Recognizes the codes in the various modes and recovers the original image data. Image data is passed to the data bus
through a decoding FIFO (DFIFO).
Image bus interface
Controls reads from and writes to image memory as well as DMA transfers on the image memory bus.
