The ISP (instruction Set Processor) notation was developed1 to precisely describe the programming level of a computer. The behavior of a processor is determined by the nature and sequence of its operations. This sequence is given by a set of bits in primary memory (a program) and a set of interpretation rules (usually in the central processor). Thus, if we specify the nature of the operations and the rules of interpretation, the actual behavior of the processor depends on the initial conditions and the particular program.
