The Book Network Message Montavista has begun to add only a dedicated opponent in Linux: a more rapid response time that is widely used in various devices including from the car computer to video players.
Although it has been committed to embedded computing devices, Montavista has not yet allow Linux to occupy considerable share in embedded markets. The embedded computing device has a demanding requirements for the response time.
Hard response time support is important in terms of mobile communication, audio play, GPS system, radar, etc. Montavista's programming staff Ditrich said that such system task-level response time requirements are between dozens - hundreds of microseconds, which is unable to reach the Linux 2.6 core.
An analyst Haf, an analyst, said that hard real-time systems are usually necessary in electronic products that are related to life safety. However, the hard real-time operating system is cost: slower average response time compared to the traditional environment. Typically, ordinary operating systems can be, especially if the system has sufficient processing capabilities. He said that as hardware is getting cheaper, in many cases, the more powerful hardware has become another option of replacing a hard real-time operating system.
Linux's nasalus Valz has some prejudice against hard real-time operating systems. He said that almost no one needs a hard real-time function, even in an embedded device. It will make the operating system more complex and increase the burden of the system. Whether the software asked Montavista will become part of the Linux kernel, he said that I personally think is unlikely, at least in this time.
In real-time system market, Montavista is not only a manufacturer that supports Linux. Traditional embedded operating system manufacturers such as Wind River, Green Hills also began to support Linux. After years of disdain, Wind River started working with Red Hat to develop real-time Linux operating systems. FSMLAB is already selling a mixed system ━━ to run Linux on hardware that supports hard real-time functions. (Notes compile)
