Most Amiga models can be upgraded either by direct CPU replacement or through expansion boards.

Most of the difficulty in the design of a superscalar CPU architecture lies in creating an effective dispatcher.

Most modern CPU designs are at least somewhat superscalar, and nearly all general purpose CPUs designed in the last decade are superscalar.

Most commonly, within some scheduling scheme, one process needs to be switched out of the CPU so another process can run.

Most commonly it is used to control video output, but it can write to most of the chipset registers and thus can be used to set audio registers or interrupt the CPU.

Most tasks are blocked or ready most of the time because generally only one task can run at a time per CPU.

Most batch processing systems for mainframe computers may also be considered " multi-user ", to avoid leaving the CPU idle while it waits for I / O operations to complete.

Most notably, the microcomputer replaced the many separate components that made up the minicomputer's CPU with one integrated microprocessor chip.

Most modern microprocessors have at least one of these features in their CPU design to make debugging easier:

Most modern CPU designs include SIMD instructions in order to improve the performance of multimedia use.

Most computers have just one CPU, but some models have several, and multi-core processor chips are becoming the norm.

Most modern CPUs increase their effective operating speeds by multiplying the system clock frequency by a factor ( the CPU multiplier ).

Most UNIX systems count only processes in the running ( on CPU ) or runnable ( waiting for CPU ) states.

Most modern systems use the target system's CPU directly, with special JTAG-based debug access.

Most host systems are ordinary commercial computers unrelated to the CPU used for development-for example, a Linux PC might be used to develop software for a system using a Freescale 68HC11 chip, which itself could not run Linux.

Most software running on x86 architecture define processing power as the model and the clock speed of the CPU.

Most players use Texas Instruments TMS320DA25x ARM plus digital signal processor as their CPU and support some version of Creative's environmental audio extensions ( EAX ).

Most trackers are optimised for speed of replay code, taking less than 3 % of CPU time.

Most spam filtering tools are very intensive users of CPU and memory.

Most instructions on most CPU architectures are sequential instructions.

Most memory-related CPU instructions can not access all the bits of 48-bit memory, but a special 48-bit register is provided for this purpose.

Most often in the console were two chips manufactured by UMC — UA6527P ( CPU ) and UA6538 ( PPU ) -- which have been integrated to be compatible with the 6502 processor and the rest of the logic.

Most notably Unreal and Unreal Tournament feature a software renderer that is able to produce enjoyable quality and performance and made use of CPU instruction set extensions like MMX.

Most of these early synchronous CPUs ran at low clock rates compared to modern microelectronic designs ( see below for a discussion of clock rate ).

Most of the Lisp systems whose designs contributed to Common Lisp — such as ZetaLisp and Franz Lisp — used dynamically scoped variables in their interpreters and lexically scoped variables in their compilers.

Most designs are a compromise between practicality and energy efficiency.

Most modern designs support multiple independently targetable reentry vehicles ( MIRVs ), allowing a single missile to carry several warheads, each of which can strike a different target.

Most modern motherboard designs use a BIOS, stored in an EEPROM chip soldered or socketed to the motherboard, to bootstrap an operating system.

Most designs are cooled by inert helium.

Most reactor designs in existence are thermal reactors and typically use water as a neutron moderator ( moderator means that it slows down the neutron to a thermal speed ) and as a coolant.

Most of the terminal unit equipment used for receiving RTTY signals was homebuilt, using designs published in amateur radio publications.

Most modern FDCs bear designs, called " cachets ", related to the theme of the stamp issued.

Most of the STI staff worked on the zone art and special stages, while most of Sonic Team worked on the level designs and the programming.

Most of the designs were inspired by Italian designer Carlo Scarpa.

Most designs cope with more than 64 corners.

An enthusiast of Tangram puzzles, Loyd published a book of seven hundred unique Tangram designs and a fanciful history of the origin of the Tangram, which was, however, presented as true, and has been described as " Sam Loyd's Most Successful Hoax ".

Most steam turbines use a mixture of the reaction and impulse designs: each stage behaves as either one or the other, but the overall turbine uses both.

Most of these designs include computer-controlled machinery that copies itself.

Most, but not all, finger-operated designs are symmetrical in design, making them usable by both hands, while thumb-operated designs are by their nature asymmetric or “ handed ,” allowing the smallest examples to be held in the air.

Most recent designs are For The People and Empire of the Sun, each of which won the Charles S. Roberts Award for best game in their category.

Most of Wallace's inventions look not unlike the designs of W. Heath Robinson and Rube Goldberg, and Nick Park has said of Wallace that all his inventions are designed around the principle of using a sledgehammer to crack a nut.

Most large yachts, and up, are also cruisers, but their design varies greatly as they are often " one off " designs tailored to the specific needs of the buyer.

Most serious mass driver designs use superconducting coils to achieve reasonable energetic efficiency ( often 50 % to 90 +%, depending on design ).

Most designs are rocket engines where the energy is provided by the beam, and is used to superheat propellant that then provides propulsion, although some obtain propulsion directly from light pressure acting on a light sail structure, and at low altitude heating air gives extra thrust.

Most proposed antimatter rocket designs require a large amount of antimatter ( around 10 grams to reach Mars in one month ).

Most modern designs use a detachable magazine, which is removed for reloading.
