1.1 FEATURES
The features of the MC68030 microprocessor are:
chip implementation of the MMU and the data and instruction caches. The
enhanced bus controller and the internal parallelism also provide increased
system performance. Finally, the improved bus interface, the reduction in
costs and satisfy cost/performance goals of the system designer.
Both improved performance and increased functionality result from the on-
physical size, and the lower power consumption combine to reduce system
