...NASM is known for its simplicity and clarity, allowing developers to write assembly code that is both readable and efficient. It is commonly used in system programming, operating system development, and performance-critical applications where direct hardware control is required. The assembler is highly portable and can be used across multiple platforms, making it a standard tool in many low-level programming workflows. Its maturity and widespread adoption have made it a reliable choice for developers working close to the hardware. Overall, nasm serves as a foundational tool for understanding and implementing low-level software systems.

...It is a combined hardware/software project: a cartridge for the computer's expansion port (with a cartridge extender for a secondary cartridge), plus firmware, which is the actual MINIMON monitor. MINIMON features all commands usually expected from a debugger/monitor: Memory dump and edit, Register dump and edit, Execute code from monitor, Direct Assembler and Disassembler (all documented opcodes of the NMOS 6502), Transfer/Compare/Fill/Hunt in memory blocks, Use of breakpoints with the BRK instruction, Load/Save/Verify with any storage device. The cartridge hardware expands upon the firmware features by supplying a de-multiplexer for the $9800..$9FFF I/Ox area (where the firmware is located per default) and a versatile reset button (with autostart inhibit for secondary cartridges). ...

This project is a partial overhaul of the Arduino hardware library, i.e. the main source files that make the core library. The intent is to reduce the overhead introduced by the initial library and eliminate the numerous function calls whenever direct register access is possible.

...The framework allows others to build custom (security-sensitive) hypervisor-based solutions (called "hypapps"). XMHF advocates a "rich" single-guest execution model where the hypervisor framework supports only a single-guest and allows the guest direct access to all performance-critical system devices and device interrupts. XMHF currently runs on recent multicore x86 hardware virtualized platforms with support for dynamic root of trust and nested (2-dimensional) paging. The framework is capable of running unmodified legacy multiprocessor capable OSes such as Windows and Linux. ...

VM02 is a Java compatible environment for the Apple II series of computers. Most basic features of a Java VM are implemented to allow direct execution of standard Java class files on a 64K, 8 bit, 1 MHz Apple II computer.
