CPU and computer hardware design is a complex field that requires a multidisciplinary approach. Key educational paths include electrical engineering and computer engineering, which are recommended for those pursuing a career in this area. Modern CPU design involves large teams with diverse specializations, and much of the design work is done using software languages like VHDL and Verilog, primarily by individuals with electrical engineering backgrounds. While there are opportunities for independent projects in low-power and embedded CPU design, the majority of significant CPU development is collaborative and requires extensive experience. Salary information can be found on platforms like PayScale, and understanding key concepts such as computer architecture, VLSI, digital design, and related technologies is essential for anyone interested in this field.
