Freescale PowerPC PowerQuicc-III MPC8555
The LinuxLink software distribution model enables the usage of the MPC8555 LinuxLink for development targeting all designs based on MPC8555E processor. Through its PowerQUICC III platform architecture, the MPC8555E combines the powerful Book E PowerPCT e500 core and communications peripheral technology to balance processor performance with I/O system throughput.
Processor derivatives enabled:
The MPC8555 LinuxLink can also be used as a starting point for Linux development for designs based on the MPC8541E processor.
Reference boards/OEM boards enabled:
The MPC8555 LinuxLink can also be used as a starting point for Linux development for designs derived from:
Notes:
Complete peripheral support for MPC8555E derived integrated processors, or board support for other reference designs, might need to be sourced from manufacturers of the respective processors or reference boards.
Processor Overview
Freescale’s MPC8555E device integrates two processing blocks: a high-performance e500 core that implements the enhanced PowerPC Book E instruction-set architecture and a RISC-based Communications Processor Module (CPM) that supports a wide range of communications peripherals. This innovative architecture is designed to reduce power consumption and to offer a more balanced approach to processing than traditional processor architectures. The CPM offloads low-level peripheral communications tasks, enabling the embedded e500 core to manage high-level processing tasks.
The MPC8555E device’s high level of integration helps to simplify board design and enhances system-level bandwidth and performance. In addition to the e500 core and CPM, the MPC8555E features an integrated security engine, a double data rate SDRAM (DDR SDRAM) memory controller, dual Gigabit Ethernet controllers, a four-channel DMA controller, and a 64-bit PCI controller that can also serve as two 32-bit PCI ports. Dual on-chip PCI support provides a cost-effective alternative to separate, discrete PCI bridges and chipsets for I/O-intensive applications that require multiple PCI interfaces. In addition to these features, the MPC8555E provides a local bus controller and I2C support.

Boards and Reference Distributions
LinuxLink software for the MPC8555 has been validated on the MPC8555CDS reference board from Freescale.
The CDS system is designed to aid hardware and software developers of the PowerQUICC III family by providing an evaluation platform for MPC8555E and MPC8541E derivatives in the 783-pin FC-PBGA package.
The CDS system is preloaded with U-Boot and a Linux reference distribution. It has a 256MB DDR SDRAM DIMM module and 2 banks of Flash that are 64Mb each. The onboard interfaces include JTAG/COP, USB, Dual UART, Dual PCI, 10/100/1000 Base-T Ethernet interface, and a 155 Mbps ATM UNI with an optical interface.
