A Simulation of the IHAS-4 Computer.
Abstract
The paper develops an Algol computer model (simulator) of the IHAS-4 airborne digital computer. The simulator is used as a tool in debugging machine language computer programs and in evaluating the relative efficiency of computer hardware alternatives in meeting requirements based upon relative speed and memory specifications. The simulator consists of a memory, an input/output section, a set of routines corresponding to the set of instructions for the IHAS-4 computer, and a monitor. The simulator program decodes each machine language instruction and performs the operation normally performed by the simulated computer. The accuracy of the arithmetic operations is comparable to the IHAS-4 computer since its word length is preserved. The 'Time' output of the simulator is based upon the real time execution for the IHAS-4 computer and is intended for real time applications. (Author)
