D.2 QUICC ARCHITECTURE OVERVIEW
The QUICC is 32-bit controller that is an extension of other members of the Motorola
M68300 family. Like other members of the M68300 family, the QUICC incorporates the inter-
module bus (IMB). (The MC68302 is an exception, having an M68000 bus on chip.) The IMB
provides a common interface for all modules of the M68300 family, which allows Motorola
to develop new devices more quickly by using the library of existing modules. Although the
IMB definition always included an option for an on-chip 32-bit bus, the QUICC is the first
device to implement this option.
The QUICC consists of three modules: the CPU32+ core, the SIM60, and the CPM. Each
module uses the 32-bit IMB. The MC68360 QUICC block diagram is shown in Figure D-1.
