Embodiment Construction
[0067] The performance overhead of the IPC mainly comes from two aspects. One is context switching, which can be referred to the description in the background technology section. The context appearing in this application generally refers to the thread (or process) context, specifically, refers to various states of a thread (or process) maintained in an operating system, usually including registers used by threads, page tables, Thread private storage, thread metadata, and more. The second is the overhead of data transmission. To complete cross-process data transfer, copy or shared memory solutions are usually used. Using copy will bring a lot of performance overhead, especially for some applications with relatively large data flow; while the shared memory solution can theoretically achieve zero copy, but there is a check time to use time (Time of Check to Time of Use, TOCTTOU) ) security issues.
[0068] The solution provided by this application is a software-hardware synerg...
