'''Atom''' is a [[___domain-specific language]] (DSL) in [[Haskell (programming language)|Haskell]], for designing [[Real-time computing|real-time]] [[Embedded programming|embedded]] software.
== Overview ==
Atom is a concurrent programming language intended for embedded applications. Atom features [[Compile time|compile-time]] [[Scheduling (computing)|task scheduling]] and generates code with deterministic execution time and memory consumption, simplifying [[worst case execution time]] analysis for applications that require [[Realtime computing|hard realtime]] performance. Atom's concurrency model is that of [[Atomic action|guarded atomic actions]], which eliminates the need for, and the [[Lock_(computer_science)#The_problems_with_locks|problems]] of using, [[Lock (computer science)|mutex locks]].
By removing [[Run time (program lifecycle phase)|run-time]] task scheduling and mutex locking—two services traditionally served by an [[Real-time operating system|RTOS]]—Atom can eliminate the need and overhead of an [[Real-time operating system|RTOS]] in embedded applications.
