PowerQUICC
PowerQUICC is the name for several PowerPC- and Power ISA-based microcontrollers from Freescale Semiconductor. They are built around one or more PowerPC cores and the Communications Processor Module (QUICC Engine) which is a separate RISC core specialized in such tasks such as I/O, communications, ATM, security acceleration, networking and USB. Many components are System-on-a-chip designs tailor-made for embedded applications.
PowerQUICC processors are used in networking, automotive, industrial, storage, printing and consumer applications. Freescale are using PowerQUICC processors as a part of their mobileGT platform.
Freescale also manufactures QUICC microcontrollers based on the older 68k technology.
There are four distinct lines of processors, mainly based on processing power.
The MPC8xx family was Motorola's first PowerPC based embedded processors, suited for network processors and system-on-a-chip devices. The core is an original implementation of the PowerPC specification. It is a single issue, four stage pipelined core with MMU and branch prediction unit with speeds up to 133 MHz. The MPC821 was introduced in 1995 together with MPC860 with a complete QUICC engine. A slimmed down version, MPC850 with reduced caches and IO ports came in 1997. The QUICC communication processor module (CPM) offloads networking tasks from the CPU, thus branding this family as PowerQUICC. All processors in the family differ in on-chip features like USB, serial, PCMCIA, ATM and Ethernet controllers and different amount of L1 caches ranging from 1 KiB up to 16 KiB.
MPC8xx – All PowerQUICC processors share this common naming scheme.
PowerQUICC II was introduced in 1998 and is the direct descendant of PowerPC 603e and the core also goes under the name 603e or G2. The processors still have 16/16 KiB instruction/data L1 caches, and are reaching frequencies up to 450 MHz. These communications processors are used in applications like VoIP systems, telecom switches, cellular base stations and DSLAMs. The PowerQUICC II family of processors are phased out in favour for the more powerful PowerQUICC II Pro line. There's no plans for further development of this core.
