Overview
The IXP42X product line and IXC1100 control plane processors are multi-function
processors and incorporate many advanced architecture features, including an
industry-standard, 32-bit PCI controller, UART, PC133 SDRAM memory controller,
interrupt controller, Intel XScale
5TE instruction set architecture (ISA), USB (device only), UTOPIA-2, GPIO, 133-MHz
internal bus, AHB bridges, timers, 8-Kbyte Queue Manager, PMU, Network Processor
Engines (NPEs), and industry-standard Media Independent Interfaces (MII).
With the highly integrated solution and rich feature set, the processors deliver high
performance system-on-chip and helps to reduce the overall cost of system
implementations.
The processors can operate at a variety of frequencies, allowing systems designers to
trade off performance for lower power consumption. The Intel XScale
Microarchitecture and the internal components are clocked from an internal PLL. The
internal and external interfaces use a 66/133-MHz, 32-bit data bus; a 32-bit address
bus; and control signals that enable the interface between the Intel XScale
Microarchitecture and peripheral logic to optimize performance.
