it as putting together code fragments that do various little jobs. (This is a little higher-level than just thinking of it as a sequence of machine instructions.) Write short, little code fragments to perform the following tasks: (a) Add two 32-bit numbers, one in file registers 0x800 and 0x802, and the other in file registers 0x804 and 0x806 ttle-endian format: most significant word in the second register in eaclh case. (b) Write a loop (its body consisting, in this case, of only a NOP instruction) which will execute exactly a number of times determined by the value of the working register, wO. (So, if wO (c) Load the address of a variable (defined in a .bss segment statement as "foo: .space 4") (d) shift left 4 bits a 64-bit value, implemented as 4 consecutive 16-bit memory locations, the contains 33, the NOP in the loop should be executed exactly 38 times) into w4. address of which is in w1
