... Freescale Semiconductor, Inc. EC000 CORE PROCESSOR The core processor is the heart of an integrated processor; it supervises system functions, makes decisions, manipulates data, and directs I/O. The EC000 core is a core implementation of the MC68000 32-bit microprocessor architecture. The programmer can use any of the eight 32-bit data registers for fast manipulation of data and any of the eight 32-bit address registers for indexing data in memory ...

... Freescale Semiconductor, Inc. DRAM CONTROLLER DRAM is used in many systems, since it is the least expensive form of high-speed storage available. However, considerable design effort is often spent designing the interface between the processor and DRAM. The MC68306 contains a full DRAM controller, greatly reducing design time and complexity. ...
