Universal CRC (Cyclic Redundancy Check) implementation
CRC (Cyclic Redundancy Check) Support CRC8, CRC16, CRC24, CRC32, CRC64 Supports single calculation and divided calculation Support custom parameter models Supports code generation (C/C++) Warehouse address python:skb666/CRC c/c++:skb666/libcrc How to use Known parameter model from crc import CRC # Instantiate a CRC, the parameter model uses crc32_mpeg2 crc32_mpeg2 = CRC(“crc32_mpeg2”) data1 = b’hello ‘ data2 […]
Use of Android CyclicBarrier
Allows any number of threads to wait until all cooperating threads reach a certain point, and then all threads continue execution from that point Constructor public CyclicBarrier(int parties) {<!– –> this(parties, null); } public CyclicBarrier(int parties, Runnable barrierAction) {<!– –> if (parties <= 0) throw new IllegalArgumentException(); this.parties = parties; this.count = parties; this.barrierCommand = […]
3.1.3 [Headed two-way (non-cyclic) linked list]
1. Concept A doubly linked list means that it can be searched from front to back or from back to front, which means that the node of the linked list cannot have only one pointer field next, you also need a pointer field prior pointing to the previous node The head pointer points to the […]
CyclicBarrier for Aqs.
Today we will learn about the “outer disciple” of the AQS family: CyclicBarrier. Why is Cyclic Barrier said to be the “outer disciple” of the AQS family? That’s because CyclicBarrier itself and the internal class Generation do not inherit AQS, but the source code implementation relies heavily on ReentrantLock, a member of the AQS family. […]
Cyclic redundancy check code (CRC check)
CRC online calculation CRC stands for Cyclic Redundancy Check: it is the most commonly used error checking code in the field of data communications. Its characteristic is that the length of the information field and check field can be selected arbitrarily. Cyclic redundancy check (CRC) is a data transmission error detection function that performs polynomial […]
Unity Skill Editor: Use directed acyclic graph to flexibly build skills
Basic structure of skill nodes Skill effects will be split into sub-units (SkillNode), and each unit can be flexibly combined to generate skill effects. Each unit should have the following characteristics: InputChannel and OutputChannel Each SkillNode must have at least one input channel (InputChannel) or output channel (OutputChannel). At the same time, a SkillNode cannot […]
Understanding of source code level of cyclictest measurement delay mechanism tool (1)
1. Rough understanding I still remember when I first used this delay measurement tool, my understanding of him is shown in the figure below. The delay measured by the cyclictest timing thread is the difference between “The moment when the task is awakened” and “The moment when the task actually runs“, as shown in the […]
JUC concurrent programming synchronizer (Semaphore, CountDownLatch, CyclicBarrier, Exchanger, CompletableFuture) with related interview questions
Directory 1.Semaphore (resource scheduling) 2.CountDownLatch (child thread priority) 3.CyclicBarrier (fence) 4. Exchanger (public exchange area) 5. CompletableFuture (asynchronous programming) 1.Semaphore (resource scheduling) Since the system resources are not unlimited, if the multi-thread requests are endless, it will cause a very heavy burden on the system. Semaphore resource scheduling is introduced in JUC, which allows threads […]
