Summary

This white paper explains how 64-bit Windows can be transformed to provide software-only, hard real-time performance by adding a separate scheduler on multicore systems. Readers will learn the architectural approach, trade-offs, and practical techniques for achieving deterministic latency, prioritized task scheduling, and software-defined peripherals on industrial Windows PCs.

Key Takeaways

• Describe the architecture of adding a separate real-time scheduler to 64-bit Windows and how it isolates deterministic workloads
• Measure and reduce interrupt and scheduling latency on multicore multiprocessors to meet hard real-time requirements
• Implement software-defined peripherals and device virtualization to deliver precise I/O timing entirely in software
• Prioritize and schedule real-time tasks alongside rich graphics and user interfaces without compromising determinism
• Assess safety, certification, and integration considerations for industrial, vision, and medical systems

Who Should Read This

Embedded/firmware engineers and system architects building industrial, vision, or medical systems who need to add hard real-time determinism to 64-bit Windows-based platforms.
