The Intel Atom processor (codenamed Silverthorne and Diamondville) is Intel's newest embedded processor, targeting the embedded and ultra-mobile PC markets where low power is of utmost importance. Atom implements the IA-32 instruction set, which has a long and rich legacy. The Intel 8088 processor was used in the original IBM PC in the 1980s. As time has progressed, Intel has added new hardware and software features to each new generation. The 80386 processor is normally regarded as the baseline for the IA32 instruction set. However, as software compatibility with the original IBM PC and the 8088 is necessary, this class also covers the key aspects of the original IBM PC architecture (such as memory map). This class examines the evolution of the platform to assist in understanding the reasons for the architecture. The Front Side Bus (FSB) protocol interfaces to the remainder of the system board components via the chipset.
