Description
High Throughput
The PM-22 can handle letter-sized 300 dpi documents in less
than 45 milliseconds and 600 dpi documents in less than 150
milliseconds. With a maximum clock speed of 75 MHz, the
PM-22 delivers a typical throughput of 225 Mpixels/second for
ITU G3 and G4 data. The worst-case throughput for any
compression/decompression standard is 75 Mpixels/second.
Integrated SRAM and PLL
To maximize cost-effectiveness, the PM-22 has integrated SRAM
and Phase-Locked Loop (PLL). The PM-22's 16 KB of integrated
SRAM reduces overall system cost. Its integrated PLL enables
the PM-22 to generate its main internal clock frequency from a
lower-frequency signal for reduced emissions and simplified
board design.
32-bit I/O Interface
The PM-22 features a new interface mode that enables it to be
connected directly to 32-bit system busses. It allows use of a
32-bit host port for input, output or both. An 8-bit or 16-bit
peripheral port is also provided. Input and output data bit and
byte reordering functions have been expanded in the PM-22 to
include word-swapping.
JBIG Compression
JBIG offers compression ratios up to four times higher than with
two-dimensional ITU Group 4 encoding methods. This
improvement significantly increases system performance and
reduces image storage and transmission costs.
