C to lc3 assembly
WebFeb 2, 2015 · There is no direct operator to subtract using LC3. You need to use 2's complement. R1 = R2-R3; //This is not possible. // using 2's Complement method R1 <- NOT R3; R1 <- R1+1; R1 <- R2+R1; Register R1 will have the subtraction result. You can use your comparison code to print out the smaller number Share Improve this answer Follow WebSep 3, 2015 · Add a comment 1 Answer Sorted by: 2 You're right with the breakdown of this instruction. The offset 000100000 that remains is indeed 32 in decimal or x0020 in hex. This offset must be taken from the end of the current instruction. Since the current instruction is at x3100 the end of it is at x3101.
