Coherent Shared Memory refers to a design where multiple cores in a system have small private caches but share a large last-level cache that is kept consistent with all private caches to ensure data coherence. AI generated definition based on: Networks-On-Chip, 2015 ...
除了C/C++之外,编程语言中也有对共享内存的本地支持。例如,PHP提供了一个创建共享内存的API,类似于POSIX函数。 3 参考 https://en.wikipedia.org/wiki/Shared_memory https://www.geeksforgeeks.org/ipc-shared-memory/ https://apiacoa.org/teaching/big-data/smp.en.html https://www.tutorialspoint.com/in...

Android Anonymous Shared Memory 简介 我们都知道Android是基于Linux内核搭建的一个分层系统,其中有kernel层,RunTimeLib和其他lib层,Framework层,Application层。虽然Linux os带了很多IPC的机制,其中Sharedmemory也有两种,但是在android系统里面,是没有这些内容的,android的linuxkernel你可以理解为是一种深度定制版,...
