PSOS (real-time operating system) (original) (raw)
pSOS (Portable Software On Silicon) — это операционная система реального времени (ОСРВ), созданная примерно в 1982 году Альфредом Чао и разработанная / продаваемая компанией Software Components Group (SCG). В 1980-х годах завоевал рынок встроенных систем, основанных на архитектуре семейства Motorola 68000, поскольку она была написана на ассемблере 68000 и была сильно оптимизирована под него. Он также был модульным, с ранней поддержкой отладки с учётом ОС, подключаемых драйверов устройств, стеков TCP/IP, языковых библиотек и дисковых подсистем. Позже появилась отладка на уровне исходного кода, поддержка многопроцессорных систем и дополнительные сетевые расширения.

| dbo:abstract | pSOS (Portable Software On Silicon) is a real-time operating system (RTOS), created in about 1982 by Alfred Chao, and developed and marketed for the first part of its life by his company Software Components Group (SCG). In the 1980s, pSOS rapidly became the RTOS of choice for all embedded systems based on the Motorola 68000 series family architecture, because it was written in 68000 assembly language and was highly optimised from the start. It was also modularised, with early support for OS-aware debugging, plug-in device drivers, Internet protocol suite (TCP/IP) stacks, language libraries, and disk subsystems. Later came source code level debugging, multiprocessing support, and further computer networking extensions. In about 1991, Software Components Group was acquired by Integrated Systems Inc. (ISI) which further developed pSOS, then renamed as pSOS+, for other microprocessor families, by rewriting most of it in the programming language C. Attention was also paid to supporting successively more integrated development environments, culminating in pRISM+. In July 1994, ISI acquired Digital Research's modular real-time multi-tasking operating system FlexOS from Novell. In 1995, ISI offered a pSOSystem/NEST package for Novell Embedded Systems Technology (NEST). In February 2000, ISI was acquired by Wind River Systems, the originators of the rival RTOS VxWorks. Despite initial reports that pSOS support would continue, development was halted. Wind River announced plans for a 'convergence' version of VxWorks which will support pSOS system calls, and that no further releases of pSOS will occur. NXP Semiconductors acquired pSOS for TriMedia from Wind River and continued to support this OS for the TriMedia very long instruction word (VLIW) core.
