Kernel subsystem for thread management and synchronization

An implementation of a small, but completely functional thread management subsystem for a preemptive, time-sharing operating system kernel. The solution implements and allows concurrent execution of multiple user-written threads on an Intel 8086 compatible CPU. The system provides a support for simple IPC using UNIX-like signal sending/handling, as well as semaphore and event synchronization primitives.

Notes

• Subsystem is implemented in C++ (non-standard, pre-C++98), and compiled by the Borland C++ Compiler compiler bcc, version 3.1 (with the huge memory model).
• Some low-level functionality in written in assembly language for Intel 8086 and compatible processors.
• The solution is target and tested on the 32-bit Windows 7 operating system.
• Source, header, and library file names must not be longer than 8 characters.
• lib/APPLICAT.LIB library implements the Scheduler class for thread scheduling.
