Operating Systems written in FPC/es
Hoy en día existen varios intentos de escribir un sistema operativo desde cero basado en Pascal. El siguiente listado, probablemente incompleto, contiene una aproximación del uso de FreePascal para crear un Sistema Operativo.

Un Sistema Operativo escrito desde cero utilizando el compilador FreePascal.
StreamOS
StreamOS es un Sistema Operativo de 32-bits escrito en Object Pascal utilizando el compilador FreePascal. Diseñado para:
- Tareas científicas tales como cálculos largos.
- Encontrar la mejor arquitectura de Kernel mixto.
- Intereses académicos.
Las principales ventajas que ofrece son:
- Kernel rápido de 32-bits.
- Kernel sin bloqueos globales.
- Modelo de hilos paralelos completo.
- API fácil;
- Soporte de Sistema Integrado de Ficheros Virtual llamado StreamFS;
- Unix-likeness.
TORO Kernel
TORO es un Kernel creado en Pascal utilizando el compilador FreePascal. El proyecto comenzó en el año 2003 por Matias E. Vara utilizando un Kernel monolítico. .The whole kernel is included in a RTL compliant with FreePascal for i386 and AMD x86-64 processors. The user program is compiled within the kernel and is executed in kernel mode. The intrinsic OS design select strict model in data workflow and pipeline of execution in order to avoid concurrent execution on the same shared memory region. The kernel was optimized for Multicore system and that is the principal objective of the project ,fix the current problems of Modern O.S. in Multicore environment. The main features are:
- Supports Multithreading with SMP(Symmetric MultiProcessing).
- Simple interface with Lazarus IDE for programmers.
- Supports AMD x86-64 and Intel EMT64 architecture.
- Designed to optimize the use of AMD HyperTransport technology and Intel Quick Path Interconnect technology.
- NUMA Memory Model (Non Uniform Memory Access).
- Stack TCP-IP.
- Virtual Filesystem.
- Independent of architecture.
FP-RTOS
A realtime kernel for embedded development. Primarily developed for ARM devices. Written entirely in Pascal and inline assembler.
- Preemptive multitasking
- Synchronization primitives(Mutex, Critical section, spinlock, and signals)
- Threadsafe queue and delays
- Optional safety features: Deadlock detection, priority inheritance, etc
