The elements of the array are all initialized to 0 except the first element which is takes the value 1, thus ensuring successful lock acquisition by the first thread in the queue. On a lock release, the hold is passed to the next thread in queue by setting the next element of the array to 1. The requests are granted to the threads in FIFO ordering.
A phase-locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is fixed relative to the phase of an input signal. Keeping the input and output phase in lockstep also implies keeping the input and output frequencies the same, thus a phase-locked loop can also track an input frequency.
Similar classes are also available through std::auto_ptr in C++98, and boost::shared_ptr in the Boost libraries. Also, messages can be sent to network resources using RAII. In this case, the RAII object would send a message to a socket at the end of the constructor, when its initialization is completed.
In electronics, a delay-locked loop (DLL) is a pseudo-digital circuit similar to a phase-locked loop (PLL), with the main difference being the absence of an internal voltage-controlled oscillator, replaced by a delay line.
Injection pulling and injection locking can be observed in numerous physical systems where pairs of oscillators are coupled together. Perhaps the first to document these effects was Christiaan Huygens, the inventor of the pendulum clock, who was surprised to note that two pendulum clocks which normally would keep slightly different time nonetheless became perfectly synchronized when hung from ...
A frequency-lock, or frequency-locked loop (FLL), is an electronic control system that generates a signal that is locked to the frequency of an input or "reference" signal. [1]
The Oxbridge tutorial system was established in the 1800s at the University of Oxford and the University of Cambridge in the United Kingdom. [1] It is still practised today, and consists of undergraduate students being taught by college fellows, or sometimes doctoral students and post-docs [2]) in groups of one to three on a weekly basis.
Nim notably provides type classes which can stand in for multiple types, and provides several such type classes 'out of the box'. Type classes allow working with several types as if they were a single type. For example: openarray – Represents arrays of different sizes, sequences, and strings; SomeSignedInt – Represents all the signed ...
