System-on-a-Chip OverviewAs microelectronics and VLSI technologies have matured, the number of components on a single silicon chip has also increased, reaching the point where a complete electronic system can be inserted into a single integrated circuit. At that moment the System on Chip was born. This trend in electronics (and computers) can be described in periods of evolution. From 1960 to 1975, it was the era of mainframe computers, where integrated circuits were designed with only performance in mind. Over the next 15 years, the network era occurred; in this period VLSI technologies have evolved considerably because the main design objective was oriented towards the cost/performance ratio. Finally, since 1995 we have been witnessing the era of downsizing, in which system-on-chip technology is applied for specific applications. The industry seeks SoC design not only for the smaller form factor, but also for lower overall cost and power, higher levels of integration, and faster development. In the perception of SoC engineers, it means the extensive use of reusable IP blocks and hardware and software such as programmable processor, embedded memory, DSP, system bus and different interfaces as well as analog components. For example, to handle more inputs/outputs required by these new applications, SoC devices can be based on RISC processors (such as the ARM7 family). Always trying to integrate pre-built components to reduce the total development time of the system. Figure 1: Block diagram of the ARM7 architecture. The extensive use of "plug & play" IP blocks is what really distinguishes SoC from IC design in general; moving from a block-based design to a platform-based one. This allows for reusability of components and reduces the time it takes to develop a new product....... half the paper...... cycle time. In summary, SoC design allows you to create products in a shorter time by reducing the amount of work time using pre-existing modules, requiring less power consumption and smaller dimensions.
