Assuming I have 8GB memory, and a single register size is 32bit. How can I load the data from the memory? If there are solutions, Could you please write them in MIPS?.
Some 32-bit A profile cores support LPAE (Large physical address extension). LPAE allows for physical addresses to be greater than 32-bit. Meaning that while at any one point in time you are limited to 4GiB of visible memory, you can have more memory than that in total. But I don't think this what you meant.
