Purpose of memory alignment

...y subsystem throughput tightly bound to the execution unit throughput (aka cpu-bound); this is all reminiscent of how PIO mode was surpassed by DMA for many of the same reasons in hard drives. The CPU always reads at its word size (4 bytes on a 32-bit processor), so when you do an unaligned address...

Why do x86-64 systems have only a 48 bit virtual address space?

...re not going to see a system which needs more than that any time soon. So CPU manufacturers took a shortcut. 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 s...
