SYSTEM USAGE
easily connect to low-cost memory systems. Typical low-cost
memory systems use inexpensive EPROMs, DRAMs, and
application specific peripherals.
In this example system, which is typical of a laser printer, a 32-
bit PROM interface is used due to the size of the PDL
interpreter. An embedded system can optionally use an 8-bit

boot PROM instead. A 16-bit font/program cartridge interface
is provided for add-in cards. A 16-bit DRAM interface is used
for a low-cost page frame buffer. In this system example, a
field or manufacturing upgrade to a 32-bit page frame buffer
is supported by the boot software and DRAM controller.
Embedded systems may optionally substitute SRAMs for the
DRAMs. Finally various 8/16/32-bit I/O ports such as RS-232/
422, SCSI, and LAN as well as the laser printer engine
interface are supported. Such a system features a very low
entry price, with a range of field upgrade options including the
ability to upgrade to a more powerful member of the
RISController family.
