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系列微處理器一般有三個(gè)功能模塊組成，嵌入式 PowerPC核(EMPCC),系統(tǒng)接口單元(SIU)以及通信處理器(CPM)模塊，這三個(gè)模塊內(nèi)部總線都是 32位。
嵌入式 PowerPC核由嵌入式 PowerPC核心、指令和數(shù)據(jù)緩存(Cache)及其各自的存儲器管理單元(MMU)組成，從功能上 Power PC核可分為兩個(gè)功能模塊:整數(shù)模塊和加載/存儲模塊。整數(shù)和加載/存儲操作均由具有 32位內(nèi)部數(shù)據(jù)通道，支持 32位整數(shù)操作及算術(shù)操作的硬件直接執(zhí)行。PowerPC核中的整數(shù)模塊使用 32 X 32 bit定點(diǎn)通用寄存器，每時(shí)鐘周期可以執(zhí)行一條整數(shù)處理指令。整數(shù)模塊中的單元僅在數(shù)據(jù)隊(duì)列中的有效數(shù)據(jù)被傳輸時(shí)才被占用，這樣使得 PowerPC核一直處于低功耗工作模式。

Power QUICC

Power QUICCII 完全可以看作是 Power QUICC的**代，在靈活性、擴(kuò)展能力、集成度等方面提供了更高的性能。Power QUICC II同樣由嵌入式的PowerPC核和通信處理模塊 CPM兩部分集成而來。這種雙處理器器的結(jié)構(gòu)由于 CPM承接了嵌入式 Power PC核的外圍接口任務(wù)，所以較傳統(tǒng)結(jié)構(gòu)更加省電。CPM交替支持三個(gè)快速串行通信控制器(FCC)，二個(gè)多通道控制器(MCC)，四個(gè)串行通信控制器(SCC)，二個(gè)串行管理控制器(SMC)，一個(gè)串行外圍接口電路(SPI)和一個(gè) 12C接口。嵌入式的 Power PC核和通信處理模塊(CPM)的融和，以及Power QUICCII的其他功能、性能縮短了技術(shù)人員在網(wǎng)絡(luò)和通信產(chǎn)品方面的開發(fā)周期。

PowerQUICC III
同 Power QUICCII相比，Power QUICCIII集成度更高、功能更強(qiáng)大、具有更好的性能提升機(jī)制。Power QUICCIII中的 CPM較 Power QUICCII產(chǎn)品 200MHz的 CPM的運(yùn)行速度提升了 66%，達(dá)到 333MHz，同時(shí)保持了與早期產(chǎn)品的向后兼容性。這使得客戶能夠昀大范圍的延續(xù)其現(xiàn)有的軟件投入、簡化未來的系統(tǒng)升級、又極大的節(jié)省開發(fā)周期。Power QUICCIII通過微代碼具有的可擴(kuò)展性和增加客戶定制功能的特性，能夠使客戶針對不同應(yīng)用領(lǐng)域開發(fā)出各具特色的產(chǎn)品。這種從 Power QUICC II開始就有的微代碼復(fù)用功能，已經(jīng)成為簡化和降低升級成本的主要設(shè)計(jì)考慮。
