JBIG Control
A3.1.4.1 Overview
JBIG control is performed by converting codes using the MN86064, a CODEC LSI chip that
is fully compliant with ITU-T.85 (JBIG Facsimile Application). Major functions of the
MN86064 are listed below. The system configuration is shown on the next page.
- Coding/decoding (MH, MR, MMR, JBIG)
- Code conversion (between different types of codes)
- Scaling (Horizontal scanning = 0.1% to 400%; Vertical scanning = 0.006% to 400%)
- Decoding error processing (leading line or white line)
- Both ends white masking
- Time-division multiplexing
A3.1.4.2 Code conversion
At the time of reception, JBIG codes are converted to image data in this LSI chip. At the
time of transmission, image data is converted to MMR data and then this MMR data is
converted to JBIG data in this LSI chip.
A3.1.4.3 CPU access
This LSI chip allows both 16-bit word access and 8-bit byte access. However, since this
LSI has registers that allow only byte access, so it performs word access and byte access
only in 16-bit spaces.
The CPU read (word access) timing chart is shown on the next page.
