translated in assembler this addition and store statement would be written as follows:\nMOVE J, R0 (1 Instr. fetch + 1 Operand fetch)\nADD  K, R0 (1 Instr. fetch + 1 Operand fetch + 1 Addition)\nMOVE R0, I (1 Instr. fetch + 1 Operand store)\n\nwith a speed of 200MHz 1 cycle is 5ns (nano seconds)\nlets assume an Instr. fetch is 1 cycle, an Operand fetch/store is 3 cycles and the Addtion is 1 cycle then we get 3 + 9 + 1 = 13 cycles, 13 * 5 ns = 65ns approx.

Go for the dual core.  It is faster and more stable if you are like me who like to run many things in parallel.

A central processing unit (CPU), or sometimes simply processor, is the component in a digital computer that interprets instructions and processes data contained in computer programs. CPUs provide the fundamental digital computer trait of programmability, and are one of the necessary components found in computers of any era, along with primary storage and input/output facilities. A CPU that is manufactured using integrated circuits is known as a microprocessor. Since the mid-1970s, single-chip microprocessors have almost totally replaced all other types of CPUs, and today the term "CPU" is usually applied to some type of microprocessor.\n\nThe phrase "central processing unit" is, in general terms, a description of a certain class of logic machines that can execute complex computer programs. This broad definition can easily be applied to many early computers that existed long before the term "CPU" ever came into widespread usage. However, the term itself and its initialism have been in use in the computer industry at least since the early 1960s (Weik 1961). The form, design and implementation of CPUs have changed dramatically since the earliest examples, but their fundamental operation has remained much the same.\n\nEarly CPUs were custom-designed as a part of a larger, usually one-of-a-kind, computer. However, this costly method of designing custom CPUs for a particular application has largely given way to the development of inexpensive and standardized classes of processors that are suited for one or many purposes. This standardization trend generally began in the era of discrete transistor mainframes and minicomputers and has rapidly accelerated with the popularization of the integrated circuit (IC). The IC has allowed increasingly complex CPUs to be designed and manufactured in very small spaces (on the order of millimeters). Both the miniaturization and standardization of CPUs have increased the presence of these digital devices in modern life far beyond the limited application of dedicated computing machines. Modern microprocessors appear in everything from automobiles to cell phones to children's toys.

"The average computer user will never need more then 640k of Memory" - Bill Gates.  ;)\n\nPersonally I always tell people you can never have enough RAM.  The question is which is more relevant, processor or RAM.  I would skimp a little on the processor to increase the RAM.  I administer 3D CAD/CAM workstations here at my company.  I've always heard that CAD and GD packages are pretty comparable in their resource requierments.  So I would suggest at least 4GB of ram for your machine although you could probably get by with 2.

Hmm, I think it's simple addition. The cores are all identical. So if pushed to the limit, it should perform *close* to three times the original, namely 3.2 x 3.

I've actually pondered this myself when taking digital circuit courses... The solution , i THINK, involves having not just one large memory unit , but instead, breaking the memory into 4 or 8 or 16 or more parts and using some kind of chip-select mechanism (using a multiplexer)

apple dual core, 2 operating systems for the price of one, has many cool features. handles high end design programs without a hitch.

I use CS2, Dreamweaver and Flash 8, and I have a gig of DDR. I can only use 2 of these programs at the same time. they each require alot of system resources to operate. \n\nI would lean to the one with the AMD proccessor, I like AMD 1000 times better than Intel. But I would t least get a gig of DDR even if you are only using Photoshop alone.

you could draw comparisons, but each bit in computer works by either sending a voltage down a conductor or not. It is either on or off. Each bit sends its pulses to a register where the queue up for the processor. A 64 bit processor can process 64 bit every two or 4 clock cycles (depending on how the register works). So a 1 GHz computer can process 64 bits half a million times a second.\n\nEach neuron in the brain has many conductors coming out of it. So it can send pulses down one, two, three or many conductors to other neurons, which in turn do the same. Pretend one neuron has 8 pathways coming out, that gives 8x7x6x5x4x3x2x1 switching combinations for one cell, Thats about 40 000 combinations from one cell. Some neurons have more than this some have less. Either way it is a big difference to on or off. Factor all this by the number of nuerons in a brain and you have one complex system. Eg 2 cells gives 40000 x 40000 combinations. 3 cells give 40000x40000x40000 combinations 40 000 to the power of a few million give a massive number of switching combinations.\n\nThe other difference is that the neurons wire themselves up based on your experiences. \n\nOne similiarity is levels of memory. Fine motor control is kept in permanent up front memory. people names are kept somewhere to be triggered by facial recognition and take a while to drag out of memory.\n\nA computer keeps the commonly used stuff in L1 and L2 cache, then main memory, then hard drive.

The idea behind the RISC processor was that because it's hard to optimize hardware you'd get a faster machine if you concentrated your efforts on the few instructions you use often and then made the complex instructions out of these simple instructions. So most of what you did would be really fast and the stuff you did once in a while would be a little bit slower.\n\nRISC processors also have a lot of registers so you can keep more things in the processor, since you don't have the complex instructions that would do everything at once.\n\nThey never really quite caught up with the single core performance of CISC processors though, they have always lagged, and now more than ever. But they are way more efficient. An Intel Pentium D 2.8GHz consumes 171 Watts at idle and 244 Watts at full load, that has two cores. Our 8 core MIPS based networking processor with four threads per core, so effectively a 32 processor system, has a 200 Watt power supply and the processor doesn't get particularly hot (under 65C) with a small heatsink.

You could use a memory in look-up table configuration. Use an Eprom with the binary code input at the address lines and the output data being the gray code. The chip would have to be programmed though. MIKE

Ever heard of trees? They are just one example of a dynamic memory structure, although don't be mistaken - they don't populate themselves, it's your job as the programmer to make them do that.\n\nRawlyn.

ethere several areas of computers from minimum things to large ones. \n\nin other worlds, there are three main area: artificial intellignce, software engineering, and computer networks. And every area consists of several subareas.

My first suggestion to you would be stay away from the Sempron chip!  This chip has no thermal overload switch, and has been known to catch on fire all by itself!  I would recommend the Athalon, or Turon chip.  Also you should consider getting a minimum of 1 GB of memory, 512 MB is the bare minimum for any program.  I hope this helps, good luck!
