In the context of development in biological intervention through advanced biotechnology and the expansion of the virtual memory field in highly information-oriented society, a theme on a relationship between the physical quality of body and life has become influential again since the 1990s.
When implementing a virtual memory system, in order to perform data transfer between memory and a disk, OS(specifically, a part to process a virtual memory in a T-Kernel Extension, etc.) needs to call a disk driver.
In 1975, Hitachi developed VOS1 mainly for users of small to medium computers of the M series as the successor OS to NDOS. VOS1 supported a virtual storage function and the virtual storage access method VSAM based on the technologies of NDOS, and supported various use applications including batch processing, online processing and remote batch processing.
The FACOM 230-8 Series was comprised of 5 models-- the FACOM 230-28S, 28, 38, 48 and 58-- ranging from mid to large size, and it provided more comprehensive functionality and improved processing speed through innovations like employing a high-efficiency virtual memory system, using 1Kbit MOS IC memory, and connecting a newly developed magnetic disk unit for high capacity files 100Mbyte capacity per disk pack.
From 1974, the VOS(Virtual Operating System) series was Hitachi's mainstay OS for HITAC M series computers. VOS2, developed in 1974, was the first VOS series OS. VOS2 was equipped with functions such as virtual storage of up to 16 MB, a new virtual storage access method, a real-time processing function based on control programs, and an enhanced range of language processors.
