The MPC823 microprocessor is a versatile, one-chip integrated microprocessor and peripheral combination that can be used in a variety of electronic products. It particularly excels in low-power, portable, image capture and personal communication products. It has a universal serial bus (USB) interface and video display controller, as well as the existing LCD controller of the MPC821 device.

The MPC823 microprocessor integrates a high-performance embedded MPC8xx core with a communication processor module that uses a specialized RISC processor for imaging and communication. The communication processor module can perform embedded signal processing functions for image compression and decompression. It also supports seven serial channels--two serial communication controllers, two serial management controllers, one I2C port, one USB channel, and one serial peripheral interface.

This two-processor architecture consumes power more efficiently than traditional architectures because the communication processor module frees the core from peripheral tasks like imaging and communication.

The MPC8240 Integrated Host Processor fits applications where cost, space, power consumption and performance are critical requirements. This device provides a high level of integration, reducing chip count from five discrete chips to one, thereby significantly reducing system component cost. High integration results in a simplified board design, less power consumption and faster time-to-market solution. This cost-effective, general-purpose integrated processor targets systems using PCI interfaces in networking infrastructure, telecommunications, and other embedded markets. It can be used for control processing in applications such as routers, switches, network storage applications and image display systems.

Processor Core 

The MPC8240 Integrated Host Processor takes advantage of a small, yet powerful 32-bit, superscalar MPC603e processor core. The processor core provides floating-point support, memory management, 16-Kbyte instruction and data caches and power management features with five independent execution units. This full-featured high-performance processor core is software-compatible with microprocessors based on Power Architecture.

The MPC8308 processor is optimized for low-cost and low-power providing a highly-integrated PowerQUICC II Pro processor that addresses requirements of networking applications such as smart grid home energy gateways, data concentrators, wireless LAN access points, wireless femto base stations, consumer printing and industrial applications such as industrial control and factory automation. MPC8308 processor extends the PowerQUICC II Pro family adding higher CPU performance and high-speed peripherals with low power consumption at a very aggressive cost.

For networking applications, the gigabit Ethernet MACs support connectivity to the wired network while the PCI Express and SDIO interfaces offer connectivity to wireless LAN or 3G and 4G modem devices. The MPC8308 features integrated IEEE 1588 version 2 time synchronization offering extremely precise clock synchronization for applications such as time-sensitive telecommunications services, industrial network switches, powerline networks and test/measurement devices.The MPC8536E PowerQUICC® III is designed to deliver gigahertz-class complex application processing performance with exceptional feature integration and high-speed connectivity for IP network and advanced media processing applications. It combines a robust e500 processor core, with enhanced peripherals and interconnect technology, to balance processor performance with I/O system throughput. The MPC8536E processor includes advanced energy management features that will help enable next-generation embedded Internet media processing applications with energy efficiency levels under the environmental and governmental energy regulatory requirements.

Energy Management Advantage
The MPC8536E processor implements sophisticated power-saving modes for managing energy consumption in both dynamic and static power modes. Designers will be able to leverage these modes to efficiently match work accomplished with the correct level of energy consumed.

Power QUICC系列微处理器一般有三个功能模块组成，嵌入式 PowerPC核(EMPCC),系统接口单元(SIU)以及通信处理器(CPM)模块，这三个模块内部总线都是 32位。
嵌入式 PowerPC核由嵌入式 PowerPC核心、指令和数据缓存(Cache)及其各自的存储器管理单元(MMU)组成，从功能上 Power PC核可分为两个功能模块:整数模块和加载/存储模块。整数和加载/存储操作均由具有 32位内部数据通道，支持 32位整数操作及算术操作的硬件直接执行。PowerPC核中的整数模块使用 32 X 32 bit定点通用寄存器，每时钟周期可以执行一条整数处理指令。整数模块中的单元仅在数据队列中的有效数据被传输时才被占用，这样使得 PowerPC核一直处于低功耗工作模式。

Power QUICC

Power QUICCII 完全可以看作是 Power QUICC的**代，在灵活性、扩展能力、集成度等方面提供了更高的性能。Power QUICC II同样由嵌入式的PowerPC核和通信处理模块 CPM两部分集成而来。这种双处理器器的结构由于 CPM承接了嵌入式 Power PC核的外围接口任务，所以较传统结构更加省电。CPM交替支持三个快速串行通信控制器(FCC)，二个多通道控制器(MCC)，四个串行通信控制器(SCC)，二个串行管理控制器(SMC)，一个串行外围接口电路(SPI)和一个 12C接口。嵌入式的 Power PC核和通信处理模块(CPM)的融和，以及Power QUICCII的其他功能、性能缩短了技术人员在网络和通信产品方面的开发周期。

PowerQUICC III
同 Power QUICCII相比，Power QUICCIII集成度更高、功能更强大、具有更好的性能提升机制。Power QUICCIII中的 CPM较 Power QUICCII产品 200MHz的 CPM的运行速度提升了 66%，达到 333MHz，同时保持了与早期产品的向后兼容性。这使得客户能够昀大范围的延续其现有的软件投入、简化未来的系统升级、又极大的节省开发周期。Power QUICCIII通过微代码具有的可扩展性和增加客户定制功能的特性，能够使客户针对不同应用领域开发出各具特色的产品。这种从 Power QUICC II开始就有的微代码复用功能，已经成为简化和降低升级成本的主要设计考虑。
