12.1 ADAPTING THE MC68030 TO MC68020 DESIGNS
APPLICATIONS INFORMATION
This section provides guidelines for Using the MC68030. First, it discusses
the requirements for adapting the MC68030 to MC68020 designs. Then, it

for the MC68020. This is possible due to the complete compatibility of the
existing MC68020-based system Software and architectural differences be-
tween the two processors are also discussed. The need for an adapter is
for the MC68030.
The adapter board plugs into the CPU socket of an MC68020 target system,
for decoupling power and ground on the adapter board.

Perhaps the easiest way to first utilize the MC68030 is in a system designed
asynchronous buses of the MC68020 and MC68030. This section describes
how to configure an adapter for the MC68030 to allow insertion into an
absolute because the MC68020 and MC68030 are NOT pin compatible. Use
of the adapter board provides the immediate capability for evaluating the
software to utilize the MC68030's additional enhanced features. This adapter
board also provides a relatively simple method for increasing the perform-
ance of an existing MC68020 or MC68020/MC68851 system by insertion of a
Since the adapter board does not support of the synchronous bus interface
of the MC68030, performance measurements for the MC68030 used in this
manner may be misleading when compared to a system designed specifically
drawing power, ground, and clock signals through the socket and running
bus cycles in a fashion compatible with the MC68030. The only support
hardware necessary is a single 1K-ohm pullup resistor and two capacitors

programmer's model and instruction set of the MC68030 and for developing
more advanced 32-bit MPU with an on-chip data cache and an on-chip MMU.
