Where does intelligence run?

Explore AI that moves inference closer to the data — from the edge to the device itself.

AI inference runs at or near the point where data is generated, rather than relying on a remote cloud.

Introducing the Scheduler

To coordinate this competition, the operating system kernel relies on a core component: the Scheduler.

The Scheduler is the gatekeeper of execution. Its role is simple to state, yet highly complex to engineer: it decides which process in the Ready queue receives CPU time, and when. At this stage, we do not care how it makes this decision (which algorithm it uses). We only care about its role as the manager of execution.

Operating systems divide this task into three distinct types of schedulers, each operating on a different timescale and handling a different state of the process lifecycle.

1. Long-Term Scheduler (Job Scheduler)

* The Question: Which programs on disk should become active processes in memory? * The Purpose: When you start a program, it doesn't instantly run on the CPU. The Long-Term Scheduler determines if the system has enough RAM and resources to allocate a new process. It controls the degree of multiprogramming—the total number of active processes residing in memory. It runs slowly, only when new tasks are created.

2. Medium-Term Scheduler (Swapping Coordinator)

* The Question: Which processes should temporarily leave memory to free up RAM? * The Purpose: If too many processes are running, the system runs out of physical memory, leading to thrashing. The Medium-Term Scheduler temporarily removes inactive or blocked processes from RAM and writes their state to a swap space on disk. This is called Swapping. When memory pressure drops, it swaps them back into RAM.

3. Short-Term Scheduler (CPU Scheduler)

* The Question: Among the ready processes in RAM, who gets the CPU next? * The Purpose: This is the primary scheduler. It operates at microsecond speeds. Whenever a running process yields, finishes, or gets interrupted, the Short-Term Scheduler instantly selects the next process from the Ready Queue and dispatches it onto the CPU.

Summary: Schedulers in the Lifecycle

The diagram below visualizes exactly where these three schedulers sit and operate across the process lifecycle states:

PrajnaEdge

Engineering concepts you don't just read — you experience.
Founded in 2026.

PrajnaEdge is a technology company exploring the space between understanding technology, experimenting with ideas, and turning them into things that can be experienced.

Our Mission

To make technology easier to explore, deeper to understand, and more exciting to experience.

Our Vision

To build a technology ecosystem where curiosity, experimentation and creation continuously lead to one another.

Where it began

Embedded Systems

PrajnaEdge began with Embedded Systems — exploring the foundations that connect hardware, software and intelligent computation.

The first technology universe is built around that foundation. The journey will expand as new ideas, experiments and products emerge.

PrajnaEdge is a technology company created by Devaharsha Meesarapu.

CREATOR PROFILE

Devaharsha Meesarapu

Embedded Systems • Firmware • Edge AI

I am the engineer behind the design, development, and content of PrajnaEdge. I build low-level systems where code directly controls hardware, bridging the gap between register-level silicon behavior and intelligent edge decision loops.

ABOUT ME

I am an Embedded Firmware Engineer focused on developing software for resource-constrained systems. My experience spans bare-metal firmware, device drivers, microcontroller peripherals, and communication protocols, working across the boundary between hardware and software.

My work has involved microcontroller-based systems, real-time behaviour, hardware interfaces, and communication technologies such as CAN, CAN FD, UART, SPI, and I²C. I am particularly interested in understanding systems from the lowest level upward—from registers and peripherals to intelligent edge systems.

ENGINEERING PHILOSOPHY

Engineering is not just about writing code; it is about managing constraints, timings, and physical hardware characteristics. True mastery of complex systems comes from understanding the interactions across different layers of the stack.

This conviction is why I built PrajnaEdge—to bridge the gap between conceptual theory and direct, register-level physical reality.
