• 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.
