SAP-1 Architecture
The Simple-As-Possible (SAP)-1 computer is a very basic model of a microprocessor explained by Albert Paul Malvino . The SAP-1 design contains the basic necessities for a functional Microprocessor. Its primary purpose is to develop a basic understanding of how a microprocessor works, interacts with memory and other parts of the system like input and output. The instruction set is very limited and is simple. SAP (Simple-As-Possible)-1 is the first stage in the evolution toward modern computers. • SAP is Simple-As-Possible Computer. The type of computer is specially designed for the academic purpose and nothing has to do with the commercial use. The architecture is 8 bits and comprises of 16 X 8 memory i.e. 16 memory location with 8 bits in each location, therefore , need 4 address lines which either comes from the PC (Program Counter which may be called instruction pointer) during computer run phase or may come from the 4 a
