Computer Architecture : A Quantitative Approach Book With Sample Question Papers: Computer Architecture and Organization

The architecture is the programmer’s view of a computer. It is defined by the instruction set (language) and operand locations (registers and memory). Many different architectures exist, such as ARM, x86, MIPS, SPARC, and PowerPC. The first step in understanding any computer architecture is to learn its language.
