我花了几天打算自己写一个zero-copy的版本, 使用boost里现成的managed_shared_memory和interprocess_semphore, container/vector等库, 但压力测试一直有问题...
CSharedMemory::Open(char* sName, int nDataSize, int nTimeOut = INFINITE) CSharedMemory::Close() CSharedMemory::Write(void* pData, int nDataSize, DWORD dwTimeOut) CSharedMemory::WriteToQueue(void* pData, int nDataSize) CSharedMemory::Read(void* pData, int nDataSize, DWORD dwTimeOut)...
--- Without the kernel knowing about threads, no other thread in the process would ever run unless the first thread voluntarily give up the CPU (otherwise, you need a clock signal in the user-level thread library to force the executing thread to give up the CPU ) The point is, multithre...
TI-IPC的数据传输需结合特定物理硬件与底层驱动,方可实现两个线程在同一个设备或跨设备间进行通信。常用三种的物理传输方式包括Shared Memory、Multicore Navigator和SRIO,具体说明如下。 表2 传输方式 优点 缺点 Shared Memory 使用简单,速率较高 仅可用于单个设备IPC通信,可能与其他使用Shared Memory的任务存在竞争 Mul...
You can display all message queues in the system using the ls command as follows: ls -Rl /dev/mqueueThe size printed is the number of messages waiting. Shared memoryShared memory offers the highest bandwidth IPC available. Once a shared-memory object is created, processes with access to the...
shared memory is an ipc mechanism where multiple processes can access and modify a common region of memory. this shared memory region allows processes to share data efficiently and communicate with each other by reading from and writing to the same memory area. by using shared memory, processes ...
Types of IPCs in UNIX(UNIX 中 IPC 的类型如下): Traditional UNIX IPCs : signal, pipe, socket System V IPCs : message queue, semaphore, shared memory 例子:POSIX共享内存(Producer) 例子:POSIX 共享内存(消费者) 📌 [ 笔者 ] 王亦优 📃 [ 更新 ] 2022.9.14 ...
The server ::write()s the capnp-generated serialization, in order, into the socket FD; the client ::read()s it out of there. The orange line shows the RTT when using Flow-IPC with zero-copy enabled. In this example, app 1 is a memory-caching server that has pre-loaded into RAM ...
What is next Here are a couple of items that we are working on. Create a marketing/documentation website Once .NET supports named semaphores on Linux, then start using them.About A cross-platform shared memory queue for fast communication between processes (Interprocess Communication or IPC). ...
For examples of configurations for Ring Buffer memory, refer to the examples in pdk/packages/ti/drv/ipc/examples/.4.9.9. Writing HelloWorld App using IPCLLD¶ Step1: Initialize MultiProc with SelfId, and how many remote cores Ipc_mpSetConfig(se...
