What is the name of the memory cache that is on the same die as the processor?
Level 1 cache (L1 cache)
There is no specific name for memory caches based on physical location. CPU memory caches are named for function, not location.
As such, there are Level 1, Level 2, and Level 3 caches (and, theoretically, there's nothing preventing Levels 4 and up from being created). Each can be located anywhere (on-die, in-package, off-chip, etc.) depending on the design of the CPU and motherboard.
Modern x86 chips from Intel and AMD include up to L3 cache on-die.
Can a computer have more then 1 type of CPU?
Most computers have multiple processors, for example, a graphics processing unit (GPU) and a central processing unit (CPU). Among systems with multiple CPU, it is common to use multiple of the same CPU.
The choice to use multiple of the same processors is just a convenience which simplifies hardware and software design, but nothing in theory prevents the construction of a computer with multiple different CPU.
This would probably not economically appealing for standard computing needs like a typical PC, but specialist computers could feature specialized CPU for different tasks. Some of this specialization is already present in some modern designs; for example, the Tegra T30 features four identical processing cores, plus a fifth one that is optimized for very low power consumption. When the unit is idle or neat idle, the four powerful cores are suspended to prolong battery life.
A CPU contains a control unit and an arithmetic/logic unit
What are the factors affect the speed of CPU?
some good things to do are check your temporary internet files in Internet Explorer, if that is your browser, and make sure they are deleted. Also emptying your recycle bin frequently and deleting any old programs or files that you don't need. It's also good to have a pop-up blocker because those often slow down the internet speed of a computer.
Why is a computer processor important?
without the CPU a computer would not be able to process any data. a CPU is the logical part of the computer which actually performs the calculation which is actually done in the ALU (arithmetic logic unit) part of the processor.
How do microprocessors work in refrigerators?
== == It controls the temperature inside the fridge, so you don't have to
What is word length of microprocessor?
Microprocessors have internal data pathways and internal registers with a fixed number of bits. An 32 bit processor will process 32 bit words, a 64 bit processor will process 64 bit words. The internal registers are sized to accommodate the word length with a single transfer. Generally, the more bits a processor can handle, the faster it can run. Smaller microprocessors might only process only 8 bits or less.
A word length is the data width that can be hold by the microprocessor. The word length is represented in bits.
word length is the instruction and other data handled by computers is in the forms of words.
a word is a group of bits.
With todays standards a 1GHz processor is something you wouldn't even find being sold in todays lowest end PCs. 1Ghz was acceptable back when people were mainly using 98 and XP, XP being one of the new OS's in the day. So no, while a 1GHz processor had its day, it is not currently considered 'good' within information technology any longer.
What is the difference between machine instruction format and micro instruction format?
Micro instrution
A single instruction in microcode. It is the most elementary instruction in the computer, such as moving the contents of a register to the arithmetic logic unit (ALU). It takes several microinstructions to carry out one complex machine instruction (CISC). Also called a "micro-op" or "µop," microinstructions differ within the same computer family and even the same vendor. For example, although all are x86 chips, the microcode for Intel's Pentium 4, Pentium M and AMD's Athlon are not the same. The software programmer never sees microinstructions, and they are not documented for the public.
Machine code - simple instructions that are executed directly by the CPU.
In other words, it takes many micro instructions to make a machine code. Micro Instructions work with the ALU wheras Machine Code works directly with the CPU
What are the instructions a CPU uses?
CPU is main part of computer,It processes the data using the registers inside the CPU. These are of different types and have different purpose of use. Due to these registers the CPU done processing.
What is the difference between a microprocessor and human brain?
Both a human brain and a CPU perform computations.
A CPU is basically a serial device (a Von Neumann machine). Its computation steps are discrete. Its operations are chosen from a small set. It does some things, like arithmetic, extremely well. It never gets tired. It uses lots of energy. It interfaces with external devices (memory, ALU, Input and Output).
A human brain is a parallel interconnected device. Its computation steps are continuous. It has a large set of operations. It does some things, like face recognition, extremely well. It often gets tired. It is much more efficient energetically than a CPU. It interfaces with external devices (eyes, ears, nose, mouth, skin).
This is not even scratching the surface - Go read, say, "Goedel, Escher, Bach" in order to get a feel for how large this question is.
What are advantages of the Spiral Model?
Advantages
1. Estimates (i.e. budget, schedule, etc.) become more realistic as work progresses, because important issues are discovered earlier.
2. It is more able to cope with the (nearly inevitable) changes that software development generally entails.
3. Software engineers (who can get restless with protracted design processes) can get their hands in and start working on a project earlier.
What are some examples of microcomputers?
Desktop computers,video game consoles, laptop, etc. are the examples of micro computer. Just about any computer that you can sit on your desk as a self-contained unit is in the class "microcomputer". This includes PCs, Macs and even laptops.
Moving back in the early days:
Apple II family
Commodore 64/ 128 Listed on Guiness as the best selling Micro computer of the 80's.
Amiga
I still think the C=64/C=128 is the best micro around :-)
( If you are looking at this question right now you probably are using a microcomputer.)
What does the CPU consist of and what do the letters CPU stand for?
The letters CPU stand for Central Processing Unit. A CPU is made up of the control unit, instruction decoding unit and an arithmeticlogic unit.
What must be true before MMX SSE SSE2 and 3D Now technology can improve multimedia performance?
1. The processor must support those instructions.
2. The software must be (re)written to take advantage of them.
What is the difference bitween Pentium D Pentium R processors?
The Pentium D is basically a dual-cored version of the Pentium 4. It is nowhere near as efficient or powerful as a Core 2 Duo, and it actually generates slightly more heat than a Pentium 4.
What does a microprocessor in a TV do?
Bottemline it processes information like any other pocessor its just smaller in size. usually a micro processor in a tv is what allows settings to be changed digital channels and codes translated into a picture pr to be more exact pixil position.
A CPU typically looks like a small square with a very high number of tiny golden pins on one side, a band of green silicon around the edges, and a thick metal covering plate on top. It will usually have some kind of emblem or writing on the top.
What factors determine the power and speed of microprocessor chips?
There are several aspects which touch completely different aspects of processor design. For instance:
- Manufacturing process (e.g. "32 nm" process)
- Voltage, currents and resistance (depend on process)
- Clock speed (depends on all above, e.g. "1200 MHz")
- Available cooling (limits clock speed)
- Instruction set design (some instruction sets are faster than others)
- Number of processor cores (more cores means that individual cores work slower than a single core would)
There are even more factors, but most of them are design-specific (like slow bus clock or memory clock).
What is the function of CLKOUT pin in microprocessor 8085?
The CLK signal in the 8085 is the system clock, which is the External Input Frequency or Crystal divided by two. It can be used to develop bus control logic, because it is essentially the inverse of ALE for one half clock cycle.
What is the Advantages and Disadvantages of von neumann computer architecture?
Disadvantages
-Executes instruction serially.
-Limited by the times it takes to process each instruction.
-some registers are idle(not being used)during the fetch-decode-execute-reset-cycle.
Advantages
-Is that seperate data bus are not required.
-program locality
What are the operations of a microprocessor?
A microprocessor manipulates data in a computer system. The central processing unit acts as the brain of a computer and consists of one or more microprocessors made up of several thousand transistors on a single integrated circuit. The microprocessor works in conjunction with other parts of the computer to compute arithmetic and logic functions to handle tasks using an instruction set to perform all tasks within a computer.
Microprocessor initiated operations are operations that the microprocessor itselp start.
These are usually one of four operations.
- Memory Read
- I/O operation
- Memory write
- I/O read
How do you figure out the clock speed of a computer?
Simply click on the start button go to control panel and find the system icon and click on it the processor speed and memory should be listed or download a detailed descriptions of your computer components. Or you can download a program called Sandra.
