Suppose the instruction stbio r3, 0(r2) is issued and r2 contains 0x15 (ie 10101 in binary) What do you expect to see on address[20:0]? Your answer should be in binary and contain 0's and 1's with no leading 0 bits and no spaces.
Question
Suppose the instruction stbio r3, 0(r2) is issued and r2 contains 0x15 (ie 10101 in binary) What do you expect to see on address[20:0]? Your answer should be in binary and contain 0's and 1's with no leading 0 bits and no spaces.
Solution
The address[20:0] would be 10101. This is because the instruction stbio r3, 0(r2) means to store the contents of register r3 at the memory address contained in register r2. Since r2 contains 0x15, which is 10101 in binary, this is the address where the contents of r3 will be stored.
