A few were further expanded to 128 kB, 256 kB, or 512 kB, with home-built memory controllers / memory management units ( MMUs ).
32.
The 8086 and successors had an innovative but limited method of memory segmentation, while the 80286 introduced a full-featured segmented memory management unit ( MMU ).
33.
Address translation hardware in the CPU, often referred to as a memory management unit or " MMU ", automatically translates virtual addresses to physical addresses.
34.
Although it provides PowerPC processor support, it can only run up to Mac OS 9.0 . 4 because it does not emulate a memory management unit.
35.
Notably, when their program fails, most embedded systems simply become software failure, such as an memory management unit ( MMU ) to catch memory access errors.
36.
The cores do not contain a memory management unit ( MMU ) so they can only run a non-virtual memory variant of Linux, such as ?Clinux.
37.
Although it provides PowerPC processor support, it can run only up to Mac OS 9.0 . 4 because it does not emulate a memory management unit.
38.
He worked around the lack of a memory management unit when fork ( ) ing by copying BSS, heap and stack of the child and parent processes before scheduling each one.
39.
Physically copying the message would be too slow, so Mach relies on the machine's memory management unit ( MMU ) to quickly map the data from one program to another.
40.
For instance, Mach required a memory management unit to improve messaging by using the copy-on-write protocol and mapping ( instead of copying ) data from process to process.
