On the Feasibility of Emulating the AN/UYK-7 Computer on the AADC Signal Processing Element.
Abstract
The All Applications Digital Computer (AADC) will eventually replace the AN/UYK-7, the Navy's present standard computer; hence, it is important to determine the feasibility of emulating the AN/UYK-7 on the AADC. The AN/UYK-7 computer is difficult to emulate because it achieves its speed through concurrent and irregular use of its internal facilities. The Signal Processing Element (SPE), a part of the AADC, when slightly modified, however, becomes a capable host machine for emulating the AN/UYK-7. The authors demonstrate this with SPE routines which emulate the AN/UYK-7 instruction fetch and seven instruction execution routines. Discussed briefly are additional AN/UYK-7 instructions and it is concluded that the SPE can emulate AN/UYK-7 programs at a speed between half real time and real time. (Author)
