Someone asked "What is the difference between L2 Cache and L3 Cache?"
Well, 3 -2 = 1 (grin)
Actually it's all a matter of proiximity and size. The L1 cach is spall, extremely fast, and tightyly coupled to the processor core(s). Th eL2 cache is bigger, not quite as fast, and a bit father away. And if you have an L3 cache its even bigger and a bit slower and even father away...
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
