Compiler Monitor System (CMS-2Y) Software Language Operation in X86 Linux Computing Environments

The Lakota Tactical Emulator Ecosystem (LTEE) provides the ability to accurately execute software of legacy systems in a modern host environment. LTEE interprets the legacy software at the machine code or assembly statement level; simulates code execution with accurate clock cycle tracking; provides adaptation to host operating system methods and services, and adapts all inputs and outputs to services and devices on the host system. LTEE's approach is highly favorable in the use case when legacy code is under test, as it provides a most authentic representation of legacy software execution since it emulates binary code execution code at an assembly instruction level. Direct translation of CMS-2 code into a modern host system architecture would lose the timing and precision characteristics of existing AN/UYK-43 architecture. LTEE solves many of the problems related to translation of legacy system code, such as interfacing to legacy executives and system libraries, I/O with legacy hardware, and the intermittent use of direct code. The LTEE is being developed to execute UYK-43 legacy software in an x86/Linux host, but is extensible to other legacy hardware and hosts systems.
