6. Write medeleg register to delegate exceptions to supervisor mode. Consider ECALL and page fault exceptions. 7. Write mstatus.FS to enable floating-point (if supported). 8. Store machine mode user registers to stack or to an application specific frame pointer. ...
When a line is brought into cache and the PMP is set up with the lock (L) bit asserted to protect a part of that line, a data cache flush instruction will generate a store access fault exception if the flush includes any part of the line that is protected. The cache flush instruction...
One of the traditional issues in space missions is the reliability of the electronic components on board spacecraft. There are numerous techniques to deal with this, from shielding and rad-hard fabrication to ad-hoc fault-tolerant designs. Although many of these solutions have been extensively ...

Did we really ``open'' a real file on the hard drive? No, we are like a request from the operating system. Sometimes the operating system reads the file from the hard disk, and sometimes it returns the file to us from the cache, depending on the operating system's thinking. In this...
