Cross-Kernel Processing Running Multiple Kernels Simultaneously on a Single System
Introduction Cross-Kernel Processing is not a cosmetic optimization it is a structural break from how operating systems have traditionally been designed. Instead of forcing one monolithic kernel to handle every workload type, Cross-Kernel allows multiple specialized kernels to run simultaneously on the same hardware, each optimized for a distinct responsibility. This approach directly targets…

Building Real-Time Systems with RTOS: Achieving Deterministic Low-Latency Performance
🔹 Understanding Real-Time Systems Real-time systems are not just about running fast — they are about running predictably. In a typical computer, slight timing variations are acceptable. But in real-time applications — like industrial automation, medical equipment, or autonomous vehicles — a delay of even a few microseconds can lead to catastrophic consequences.A real-time…

Optimizing Context Switches in the Linux Kernel: Hidden Performance Leverage
1. What Context Switching Really Costs Every time the kernel performs a context switch — moving execution from one thread to another — the CPU flushes registers, updates the program counter, and reloads process metadata. This is not “free multitasking.” It burns thousands of CPU cycles.When the switch rate spikes, cache locality is destroyed…
