The document discusses System on a Chip (SoC) technology. It defines an SoC as integrating necessary computer system components onto a single silicon chip, such as a processor, memory, and peripheral interfaces. It describes how SoCs can be implemented using ASICs, FPGAs, or programmable devices. The document outlines some advantages of SoCs like decreased power consumption and smaller size, and disadvantages like high design costs. Examples of SoCs discussed include the TigerSHARC chip and Intel's Tolapai chip for mobile devices.
