HelenOS

Compare

  Analyzed about 1 hour ago

HelenOS is a microkernel-based multiserver operating system designed from scratch. It decomposes key operating system functionality into many isolated, intensively communicating server processes that reside entirely in user space. HelenOS thus provides a computing environment that has several ... [More] virtues, such as flexibility, increased robustness, well defined explicit interfaces and reduced complexity of individual components as compared to other operating systems. HelenOS runs on seven different processor architectures, ranging from a 32-bit uniprocessor little-endian ARMv4 to a 64-bit multicore big-endian UltraSPARC T1. [Less]

MINIX 3

Compare

  Analyzed about 13 hours ago

MINIX 3 is a new open-source operating system designed to be highly reliable, flexible, and secure. It is loosely based somewhat on previous versions of MINIX, but is fundamentally different in many key ways. MINIX 1 and 2 were intended as teaching tools; MINIX 3 adds the new goal of being usable as ... [More] a serious system on resource-limited and embedded computers and for applications requiring high reliability. This new OS is extremely small, with the part that runs in kernel mode under 4000 lines of executable code. The parts that run in user mode are divided into small modules, well insulated from one another. For example, each device driver runs as a separate user-mode process so a bug in a driver (by far the biggest source of bugs in any OS), cannot bring down the entire OS. [Less]

Jari OS

Compare

  Analyzed over 1 year ago

Jari OS is a real-time microkernel operating system which runs in terms of multi-service architecture. Core system consists of its own microkernel μString, core and system services, set of device drivers launched as trusted services. Our system is a pure microkernel and multi-service OS. All work ... [More] is made via trusted services, and each service works within its own address space, and in this case Jari OS is a pure multi-service OS. Jari OS provide POSIX API for threads, files, networking, timers, memory operations. [Less]
