Embedded Linux Primer: A Practical, Real-World ApproachAMCC PowerPC Some of the examples later in this book are based on the AMCC PowerPC 440EP Embedded Processor. The 440EP is a popular integrated processor found in many networking and communications products. The following list highlights some of the features of the 440EP: On-chip dual-data-rate (DDR) SDRAM controller Integrated NAND Flash controller PCI bus interface Dual 10/100Mbps Ethernet ports On-chip USB 2.0 interface Up to four user-configurable serial ports Dual I 2 C controllers Programmable Interrupt Controller Serial Peripheral Interface (SPI) controller Programmable timers JTAG interface for debugging This is indeed a complete system on chip (SOC). Figure 3-2 is a block diagram of the AMCC PowerPC 440EP Embedded Processor. With the addition of memory chips and physical I/O hardware, a complete high-end embedded system can be built around this integrated microprocessor with minimal interface circuitry required. Figure 3-2. AMCC PPC 440EP Embedded Processor (Courtesy AMCC Corporation) Many manufacturers offer reference hardware platforms to enable a developer to explore the capabilities of the processor or other hardware ...» | Код для вставки книги в блог HTML
