英语翻译Implementing data streaming systems appears to have been the primary motivation of the RT-Linux designers.But the FIFO scheme provides a pretty good way of implementing semaphores.A binary semaphore can good way of implementing semaphores.A binary semaphore can be implemented by creating a FIFO of size one.The "give" operation (also known as "V" or "signal") is then simply an rtf_put() of size one,with the content of the data insignificant and the error return ignored.The "take" operation (or "P" or "wait") is an rtf_get() with size one.A counting semaphore can be implemented simply by creating the FIFO with a size large enough to accommodate the expected number of "give" operations.So the FIFO mechanism provides most of the functionality needed for task synchronization in real-time applications.The current implementation lacks some functionality to which RTOS users are accustomed,such as priority inheritance (to prevent priority inversion) and task deletion safety.But careful design can almost always prevent the problems these features are intended to address.In addition,although the FIFO operations can be set up to block when data is not available (when reading the FIFO) or when space is not available (when writing),the syntax for doing so is rather cumbersome,as blocking capability appears not to have been a priority of the designers.Nevertheless,at least one effort is under way to provide an easy syntax for blocking operations on FIFOs.6 This effort also implements timeouts when blocking,an important feature in many embedded applications.The simple,open design of RT-Linux allows users to implement such additional favorite features quite easily.我的积分不多，但我要翻译的内容不少，我真诚的希望大家给我帮助，真诚的恳求不要机译！
