1.0 Introduction
The Intel
®
Atom™ Processor E6xx Series is the next-generation Intel
®
architecture
(IA) CPU for the small form factor ultra low power embedded segments based on a new
architecture partitioning. The new architecture partitioning integrates the 3D graphics
engine, memory controller and other blocks with the IA CPU core. Please refer to
subsequent chapters for a detailed description of functionality.
The processor departs from the proprietary chipset interfaces used by other IA CPUs to
an open-standard, industry-proven PCI Express* v1.0 interface. This allows it to be
paired with customer-defined IOH, ASIC, FPGA and off-the-shelf discrete components.
This provides utmost flexibility in IO solutions. This is important for deeply embedded
applications, in which IOs differ from one application to another, unlike traditional PC-
like applications. Figure 1 shows an example system block diagram. Section 1.3
provides an overview of the major features of the processor.
