How does the ARM architecture differ from x86? [closed]
...rom / to memory while x86 can operate directly on memory as well. Up until v8 ARM was a native 32 bit architecture, favoring four byte operations over others.
So ARM is a simpler architecture, leading to small silicon area and lots of power save features while x86 becoming a power beast in terms of...

Also, the fact that Java actually compiles down to an inherently dynamic intermediate language should be a hint that for most cases, dynamic typ...
