By anyone’s measure, Freescale has enjoyed tremendous success in the embedded
market. Part of this success goes as far back as the venerable 68K family of products,
which still capture market share today in the form of Cold fire processors. More recently, Freescale has enjoyed success with its Power QUICC product line. The Power QUICC architecture has been shipping for more than a decade. It is based on a Power
Architecture core of a particular version integrated with a QUICC engine (also called
a communications processor module or CPM in the Freescale literature). The QUICC
engine is an independent RISC processor designed to offload the communications
processing from the main Power Architecture core, thus freeing the Power Architecture
core to focus on control and management applications. The QUICC engine is a com -plex but highly flexible communications peripheral controller.
