Develop code to evaluate function calls, type casting and code flow algorithms for performance. Programming assignment 4 is exploring the use of Shared Memory (shm). // // This program configures the shm region, accepts user input, and stores // the user msg in shm. // // Scope: // Open and attach to shm region // while runable // shm allowed to write // clear message // prompt user for msg // store msg in shm // if msg begins with "end", detach from shm // allow program 2 to resume // exit // -Develop code to evaluate function calls, type casting and code flow algorithms for performance.

基于 STM32 使用 SPI_DMA 方法来实现两台计算机之间的高速通信，通信数据可以是任意的字节

系统中的多个任务在运行时，经常需要互相无冲突地访问同一个共享资源，或者需要互相支持和依赖，甚至有时还要互相加以必要的限制和制约，才保证任务的顺利运行。因此，操作系统必须具有对任务的运行进行协调的能力，从而使任务之间可以无冲突、流畅地同步运行，而不致导致灾难性的后果。本章，我们仅介绍信号量和邮箱，消息队列将会在下一章介绍。
