HeliOS – an open-source, Unix-like operating system for parallel computers developed by Perihelion Software. Helios was developed by the (now defunct) company called Perihelion Ltd., mainly targeting the INMOS Transputer but later adding other CPUs like the ARM series or TMS320c4x DSPs when INMOS’ decline became clear.

Perihelion Software Limited was a United Kingdom company founded in 1986 by Dr. Tim King along with a number of colleagues who had all worked together at MetaComCo on AmigaOS and written compilers for both the Amiga and the Atari ST.

The HeliOS primary architecture is the Transputer. The transputer is a series of pioneering microprocessors from the 1980s, featuring integrated memory and serial communication links, intended for parallel computing.
