Other projects, such as NetBSD, use a similar 2-clause license. This version has been vetted as an Open source license by the OSI as the "Simplified BSD License." The ISC license is functionally equivalent, and endorsed by the OpenBSD project as a license template for new contributions. 0-clause license ("BSD Zero Clause License")

In computer security, executable-space protection marks memory regions as non-executable, such that an attempt to execute machine code in these regions will cause an exception.It makes use of hardware features such as the NX bit (no-execute bit), or in some cases software emulation of those features. However, technologies that emulate or supply an NX bit will …

The NetBSD operating system is widely known as having a clean hardware abstraction layer which allows it to be highly portable. As part of this system are uvm(9) / pmap(9) , bus_space(9) , bus_dma(9) and other subsystems.

OpenBSD is a security-focused, free and open-source, Unix-like operating system based on the Berkeley Software Distribution (BSD). Theo de Raadt created OpenBSD in 1995 by forking NetBSD 1.0.

The i.MX range is a family of Freescale Semiconductor (now part of NXP) proprietary microcontrollers for multimedia applications based on the ARM architecture and focused on low-power consumption. The i.MX application processors are SoCs (System-on-Chip) that integrate many processing units into one die, like the main CPU, a video processing unit and a graphics …

x86-64 (also known as x64, x86_64, AMD64, and Intel 64) is a 64-bit version of the x86 instruction set, first released in 1999.It introduced two new modes of operation, 64-bit mode and compatibility mode, along with a new 4-level paging mode.. With 64-bit mode and the new paging mode, it supports vastly larger amounts of virtual memory and physical memory than was …

NetBSD-based. NetBSD is a freely redistributable, open source version of the Unix-derivative Berkeley Software Distribution (BSD) computer operating system. It was the second open source BSD descendant to be formally released, after 386BSD, and continues to be actively developed. Noted for its portability and quality of design and implementation, it is often used in embedded …
