Abstract
Lately, considerable attention has been paid to the automation of the design of digital computers and in particular to the formulation of languages and approaches to the modeling of the operation of the existing as well as of future schemes. A universal language established for the modeling of the existing digital computers would avoid the necessity for the creation of a new modeling program each time a new digital scheme is being developed. The new proposed language TsIMOD differs from the previously known by viewing an arbitrary digital scheme as being controllable by microprograms; this makes the new language more universally applicable. The present paper presents a brief semantic description of the language and describes its syntax by a structural diagram. The approach is illustrated on the case of the description of a small computer similar to the M-3. An interpreting program of the M-20 computer contains 2,000 cells in addition to 200 operating cells and constants. The description of the structural scheme of the computer occupies 240 cells. The time of modeling of a single command is on the average equal to 1.5 sec.
