The embedded systems have increase its popularity given the society evolution towards a more technology-based and automated necessities. There is no doubt about how fast this market is progressing, one reason is because more resources are being invested and second due to the constant increase in the integration capacity of the components inside the chips. For that reason, many designers need to update continuously their know-how about the methods to design SoC-based applications, which combine processing systems and programmable logic, in order to be competitive.

This chapter has been covered the evolution timeline of FPGA-based systems from its beginning until the final AP SoC chips. They are complex devices and it is necessary to have a deep understanding to utilize them in more efficient way. In this manner from all the advance digital systems, the SoCs are analyzed in more detail because they provide a solution that combines the different digital and analogic elements embedded only in one chip. That permits to develop more versatile applications but it is necessary a well-known comprehension of the analysis and design methodologies.

The introduced codesign hardware/software methodologies are very useful technique to develop time-effective applications. A good coordination between the developers of the same team is required, being the tools that can help to simulate software and hardware designs fundamental to achieve competitive results.

This study we presented the evident improvements in the SoC systems, which can run an embedded Linux for interfacing FPGA-based designs. Thus, the development of a real application has been described and the advantages over other system have been highlighted.
