What's the difference between a register and a word?
As far as I know,
- 8 bits = 1 Byte, 32 Bits = 4 Bytes = 1 Word
- A register is 32 bit, which means size of 1 register = 1 Word
- Then probably, the processor having a total of 16 registers should have a total of 16 X 1 = 16 words.
- Then what does 2^30 memory words mean in an ARM Processor? ARM Operands
- Also, is this 2^30 words concept somehow related with the 32-Bit or 64-Bit computer we use?
Can someone help me get this concept right?
Thanks in advance!
Being a 32bit architecture, the addressing area is 2^32 = 4GB.
And since each word is 4 bytes long, the total area in word is 4GB/4 = 1G words (2^30)
