WebThey don't have addresses in the system memory space and can be accessed only by specific instructions. The other is the registers that can control various hardware blocks (peripherals), in the CPU itself or external to it. On LPC1768 and many other embedded processors they're typically memory-mapped, and that's why they have addresses. WebMemory mapped by mmap() is preserved across fork(2), with the same attributes. A file is mapped in multiples of the page size. For a file that is not a multiple of the page size, the remaining bytes in the partial page at the end of the mapping are zeroed when mapped, and modifications to that region are not written out to the file.
