Webb13 aug. 2012 · In fact there are probably prototypes on a shelf somewhere. The reason you dont see them is that there isn't a market for them. (or a large enough market). There is no technical reason why you can't make an 8 bit CPU at GHz clock speeds. You can make a 32 or 64 bit one, so you just reduce the bus width. Webb27 juli 2010 · That's a huge speed advantage if you need it. So 64bit gives an advantage if you have applications that need lots of RAM (image/video/audio processing, world/universe simulations). On top of that, the 64bit CPUs also have commands that operate on 64bit data types (so you don't need to emulate those with 32bit types).

Webb12 dec. 2016 · 64 bit CPU. Address pointer size is 64 bits -> can access 2^64 (18,446,744,073,709,551,616) discrete addresses. This allows a program to make a data structure in memory up to 16 Exabytes in size. Main advantages (64-bit over 32-bit) Process on a 64-bit CPU can work with a larger set of data compared to 32-bit CPU … Webb12 apr. 2004 · A 64-bit microprocessor can process data and instructions in chunks of 64 bits during a single clock cycle, giving it the potential to address far more memory and … cp対応とは

Webb16 juli 2011 · They use an instruction set which allows a full 64-bit address space, but current CPUs just only use the lower 48 bits. The alternative was wasting transistors on handling a bigger address space which wasn't going to be needed for many years. So once we get near the 48-bit limit, it's just a matter of releasing CPUs that handle the full … WebbWhen we talk about 64 bit CPU we specifically mean the size of the data bus. At least that's what's meant by the current crop of CPUs, os and other software. It could theoretically mean other things, some of those you are talking about. But usually it doesn't. You say that a 64 bit CPU has no penalty making 32 bit operations. Webb3 sep. 2024 · The 128-bit (or higher) architecture is useful for mathematically intensive operations such as graphics, cryptography, and complex system modeling, but not for operating systems. Based on the preceding conversation, we can conclude that a system with a 64-bit processor is now sufficient for the bulk of users. cp対称性の破れ とは
