The first official ROS distribution release: ROS Box Turtle, was released on 2 March 2010, marking the first time that ROS was officially distributed with a set of versioned packages for public use. These developments led to the first drone running ROS, [37] the first autonomous car running ROS, [38] and the adaption of ROS for Lego Mindstorms ...
QF (QP Active Object Framework) is a highly portable, event-driven, real-time application framework for concurrent execution of Active Objects specifically designed for real-time embedded systems. QV (Cooperative Kernel) is a tiny cooperative kernel designed for executing active objects in a run-to-completion (RTC) fashion.
A software program can be written using the equations 1 and 2 and the estimated power weights derived from the table to estimate the power consumption at run-time. For equation 1 the program also needs 5 samples of HPCs but in this example the PXA255 processor can only sample 2 events at any given time therefore multiple code execution is ...
Least slack time (LST) scheduling is an algorithm for dynamic priority scheduling. It assigns priorities to processes based on their slack time. Slack time is the amount of time left after a job if the job was started now. This algorithm is also known as least laxity first.
When IBM introduced the P/370 and P/390 processor cards, a PC could now run full VM systems, including VM/370, VM/SP, VM/XA, and VM/ESA (these cards were fully compatible with S/370 and S/390 mainframes, and could run any S/370 operating system from the 31-bit era, e.g., MVS/ESA, VSE/ESA).

For large code bases, manually writing test cases turns out to be very time consuming. In addition, not all errors can be detected during development. Early contributions to automated verification were made at the NASA Ames Research Center by Klaus Havelund and Grigore Rosu to archive high safety standards in spacecraft, rovers and avionics ...
Testing ARMulator was always a time-consuming challenge, the full ARM architecture validation suites being employed. At over 1 million lines of C code it was a fairly hefty product. ARMulator allows runtime debugging using either armsd (ARM Symbolic Debugger), or either of the graphical debuggers that were shipped in SDT and the later ADS products.
