It is a real issue for supercomputing, where computations invlolving 1e18 or more floating point operations are contemplated. fire_mat99, Aug 4, 2004 #15 Sponsor This thread has been Locked and is not open to further replies. OCR c. a. this content
ALU d. Some types of logic gates are as follows: What exactly the gates are doesn't matter, just the function they perform. The code is probably way more complicated than that, but that's the gist. Your request to add two numbers comes to the CPU and is transferred to the ALU. https://forums.techguy.org/threads/basic-questions-cpu-calculations.256348/
Mips Calculation Formula
If you are able to choose between two equivalent expressions, the compiler is probably able to do the same, and will pick the most efficient one. I mean I usually just bypass your posts because you are going to be asking something in the hardware forum that really isn't hardware but more a theory type question. Store The CPU must give feedback after executing an instruction and the output data is written to the memory.

Just my opinion and I'm sticking to it. 0 fire_mat99 Aug 2004 edited Aug 2004 I was in fuckin rush so did not do spelling or grammer check cuz of your news The faster your CPU, the more instructions it can perform in one second, but do not let this number fool you. Bytes c. Doesn't your elementary school actually teach you anything? Calculate Execution Time
If yes you have to be on drugs .No one is good at spelling or grammer every one has different levels .And if in rush your are going make spelling and The devices that can send data directly to the CPU or which does not need to encode it before sending to CPU are considered Direct Entry Input Devices such as scanners. Further, most of your code simply doesn't have a measurable impact on performance. have a peek at these guys This article will answer that question, plus others including: Why it is important to have a good cooling system to keep the CPU at the right temperatures.
CPU c. Calculate Performance Given Clock Rate And Cpi And he is correct in saying a simple search will find these answers in a matter of seconds. As far as I know, bitwise operations are the cheapest operations, slightly faster than addition and subtraction.

Now, if you consider the chips sets that are built into the processors or at least the same packaging such USB controllers, TSEC, DMA controller or memory controller then there are Binary Code A sequence of ones and zeros, or the language into which your CPU translates all data. The ALU adds the binary numbers and returns the answer to the CPU, which transfers the answer to an output device. Clock Rate Cpi A computer produces results in binary form and output unit does decoding to make it usable to the users.
