F Prime Translation Guide: Software Engineering Terminology to F Prime Nomenclature

This guide provides a mapping between common software engineering concepts and their equivalent implementations in the F´ framework. It serves as a reference for developers new to F´ development.

Data Structures & Containers

Software Concept	F Prime Equivalent	Notes
String	Fw::String	Safe string implementation with size limits
Buffer	Fw::Buffer	Memory buffer with size tracking
Queue	Os::Queue	Thread-safe queue implementation

Note

Os::Queue is rarely used directly but rather is used via async port calls.

Communication & Synchronization

Software Concept	F Prime Equivalent	Notes
Function Call	Synchronous Port	Direct component-to-component calls
Message Queue	Async Port	Asynchronous component communication supported by a queue
Event Loop	Active Component	Components with their own execution thread
Mutex	Os::Mutex	Thread synchronization primitive
Thread	Os::Task	OS task abstraction

Note

Os::Task is rarely used directly but rather is contained within active components.

Memory Management

Software Concept	F Prime Equivalent	Notes
Stack Allocation	Local variables	Standard stack allocation
Heap Allocation	Fw::MemAllocator	Managed heap allocation
Memory Pooling	Svc::BufferManager	Fixed-size buffer management
Smart Pointer	Fw::Buffer	Buffer containing pointer, size, and context

System Architecture

Software Concept	F Prime Equivalent	Notes
Module	Component	Basic unit of functionality
Interface	Port(s)	Component communication interface
System Service	Service Component	Components providing system services
Driver	Driver Component	Hardware abstraction components
Runtime Configuration	Parameters	Component configuration management via ground-commanded parameters

Error Handling

Software Concept	F Prime Equivalent	Notes
Exception	Assert + Event	Assertion and event logging
Error Code	Status Type	Enumerated status returns
Logging	Events	System event logging framework
Debug Print	Fw::Logger	Debug output facility
