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?.

On an ARM forum ?!
The answer my friend is written in ... the reference manual. ;-)
A 32 bit processor can access 2^32 = 4,294,967,296 bytes of memory which happens to be 4 GiB. 64 bit processors can access upto 2^48 = 256*1024*1024*1024*1024 bytes of memory, which is equal to 262,144 GiB = 256 TiB (65,536 times the 32 bit processors).
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.
