P4080PCIE application field and working principle

The P4080PCIE (PCI Express) of Freescale is a family of integrated application processor devices that offers features such as a dual-core processor, on-chip peripheral device controllers, high-speed serial interfaces, PCIe interface, and graphics processor unit. It is an ideal platform for applications such as high-end embedded computing, industrial communication networks, vision systems, automotive infotainment, and other consumer applications.

The P4080PCIE consists of four main components: a dual-core processor that is based on the PowerPC architecture, an integrated system controller, a high-speed serial interface, and a graphics processor unit. The P4080PCIE’s dual-core processor, the microPCI ExpressInte, supports real-time multitask scheduling and is optimized for implementation of embedded systems. The integrated system controller offers a consolidated high-speed interface to communication peripherals such as DMA, LCD controllers, digital audio, PCI Express, memory, SDIO, and Ethernet. The high-speed serial interface is based on a full-duplex dedicated 10-bit multi-gigabit serial link. The graphics processor unit supports dual independent displays.

In addition to the main components, the P4080PCIE comes with a variety of peripherals and interfaces that enable custom development. Because of its high integration, the P4080PCIE can be quickly and easily configured for custom designs. The design can be integrated into a custom embedded board or implemented as a stand-alone product.

The P4080PCIE offers a number of features that make it a great choice for embedded applications. First, its advanced dual-core processor includes eight dedicated instructions for real-time multitask scheduling. This allows for code execution to be split between two separate cores for optimal system performance. Second, the integrated system controller supports a consolidated high-speed data interface that allows for communication with multiple peripherals. Third, the high-speed serial link enables fast throughput even for large amounts of data. Fourth, the graphics processor enables dual independent displays, LCD controllers, and other graphics capabilities. Finally, the P4080PCIE offers power savings features, such as frequency and voltage scaling, that can reduce power consumption and extend battery life.

The P4080PCIE also offers a variety of development tools that make it an attractive processor for embedded applications. It is supported by FDT (Freescale Dev Tools), which is a suite of development tools that includes compilers, assemblers, interpreters, debuggers, profilers, and other development utilities. Also, the P4080PCIE is supported by Wind River Workbench, which is a comprehensive set of software development tools that enable the rapid and cost-effective development of software for embedded systems.

In conclusion, the P4080PCIE is an ideal platform for embedded applications. Its powerful dual-core processor, integrated system controller, high-speed serial interface, and graphics processor offer a great combination of features and performance. It also offers a robust set of development tools and power savings features. For these reasons, the P4080PCIE is a great choice for embedded applications.
