Παραδείγματα χρήσης MMU σε μια πρόταση

• The 68030 is essentially a 68020 with a memory management unit (MMU) and instruction and data caches of 256 bytes each.
• It thus included all of the functionality that previously required external chips, namely the FPU and Memory Management Unit (MMU), which was added in the 68030.
• A memory management unit (MMU), sometimes called paged memory management unit (PMMU), is a computer hardware unit that examines all memory references on the memory bus, translating these requests, known as virtual memory addresses, into physical addresses in main memory.
• The machine shipped with a socket for an optional Motorola 68851 MMU, but an "Apple HMMU Chip" (VLSI VI475 chip) was installed by default and could not implement virtual memory (instead, it translated 24-bit addresses to 32-bit addresses for the Mac OS, which would not be 32-bit clean until System 7).
• Trying to access an undefined virtual memory address is generally considered to be a segmentation fault rather than a bus error, though if the MMU is separate, the processor cannot tell the difference.
• Depending on the memory model, paged memory functionality is usually hardwired into a CPU/MCU by using a Memory Management Unit (MMU) or Memory Protection Unit (MPU) and separately enabled by privileged system code in the operating system's kernel.
• The Mobile Met Unit (MMU) are a unit consisting of Met Office staff who are also RAF reservists who accompany forward units in times of conflict advising the armed forces of the conditions for battle, particularly the RAF.
• The MMU allowed the astronauts to perform untethered extravehicular spacewalks at a distance from the shuttle.
• Nelson, using the Manned Maneuvering Unit (MMU), flew out to the satellite and attempted to grasp it with a special capture tool, called the Trunnion Pin Acquisition Device (TPAD).
• On February 7, the fourth day of the mission, astronauts McCandless and Stewart performed the first untethered spacewalk, operating the Manned Maneuvering Unit (MMU) for the first time.
• It featured a newly designed superscalar RISC core and added an unusual addressable on-chip cache, but lacked an FPU and MMU, as it was intended for high-performance embedded applications.
• OSEK is expected to run on microcontroller without memory management unit (MMU), which is favored for safety-critical systems such as cars, therefore features of an OSEK implementation will be usually configured at compile-time.
• The arithmetic logic unit (ALU) of the microPrism version had completed design in April 1988 and samples were fabricated, but the design of other components like the floating point unit (FPU) and memory management unit (MMU) were still not complete in the summer when DEC management decided to cancel the project in favor of MIPS-based systems.
• Gardner and Allen completed two spacewalks totaling 12 hours and flew the Manned Maneuvering Unit (MMU) backpack during the salvage operation.
• The STS 41-B mission marked the first checkout of the Manned Maneuvering Unit (MMU), and Manipulator Foot Restraint (MFR), with Bruce McCandless II and Bob Stewart performing two EVAs (spacewalks).
• From 1979 to 1983, Griggs was involved in several Space Shuttle engineering capacities including the development and testing of the Head-Up Display (HUD) approach and landing avionics system, development of the Manned Maneuvering Unit (MMU), and the requirements definition and verification of on-orbit rendezvous and entry flight phase software and procedures.
• The Z280 was fabricated in CMOS, added a memory management unit (MMU) to expand the addressing range to 16 MB, features for multitasking and multiprocessor and coprocessor configurations, and 256 bytes of on-chip static RAM, configurable as either a cache for instructions and/or data, or as part of the ordinary address space.
• Other types of caches exist (that are not counted towards the "cache size" of the most important caches mentioned above), such as the translation lookaside buffer (TLB) which is part of the memory management unit (MMU) which most CPUs have.
• Tamara Marie Watson – Angela Perry, an astronaut who was rendered unconscious when the Earth imploded, waking up disoriented five years in the past, in her MMU about to burn up in the atmosphere.
• With the exception of six Manned Maneuvering Unit (MMU) sorties in 1984 and a test of the Simplified Aid For EVA Rescue (SAFER) in 1994, all other orbital spacewalks have involved a safety tether, anchoring the spacefarer to the spacecraft at a short distance.
• But architectures can still be fully virtualized (in the x86 case meaning at the CPU and MMU level) by using different techniques like binary translation, which replaces the sensitive instructions that do not generate traps, but hardware traps have non-negligible performance cost as well.
• Because most operating systems use paged virtual memory, and granting the guest OS direct access to the MMU would mean loss of control by the virtualization manager, some of the work of the x86 MMU needs to be duplicated in software for the guest OS using a technique known as shadow page tables.
• Siti Hasmah binti Haji Mohamad Ali (Jawi: سيتي حسمه بنت محمد علي; born 12 July 1926) is married to Mahathir Mohamad, the 4th and 7th Prime Minister of Malaysia and former chancellor of the Multimedia University (MMU).
• The first Am29000 was released in 1988, including a built-in MMU but floating point support was offloaded to the Am29027 FPU.
• Rosetta was a memory management unit (MMU), and it provided the ROMP with address translation facilities, a translation lookaside buffer, and a store buffer.
