Webcore with FPGA boards and ported two microkernel implementa-tions, seL4 and Zircon, and one monolithic kernel implementation, Android Binder, for evaluation. We also implement XPC on GEM5 simulator to validate the generality.

Web18 jun. 2024 · In the monolithic system, the service is obtained by a single system call, which requires two mode switches (changes of the processor’s ring or CPU mode). In the microkernel-based system, the service is obtained by sending an IPC message to a server, and obtaining the result in another IPC message from the server. WebTechnically, any means of sharing data can be considered IPC (e.g. files, networking, middleware) In monolithic systems, this usually works without using a dedicated IPC …

Web11 okt. 2011 · The kernel can for example temporary store the IPC data in the kernel for small sizes. It can copy from one address space to another by mapping a part of the receiver's address space in the kernel. There are several methods here.
