WebSep 26, 2014 · Sorted by: 14. Registers are very, very expensive because they have to be very, very fast and they need to be accessed from many places simultaneously. For example if you have statements a = a + x; b = b + x; c = c + x; you have three instructions which all want to read the same register. So the register is not just the memory. WebJun 6, 2016 · A typical modern computer can store a few hundred bytes of data in registers within each core of the processor. The data in the registers may be explicitly moved to or from more distant devices, or may be created by the core and lost when overwritten.
