Question
1. Show of work is not necessary for this problem. 1) Give an instruction in LC-3 that corresponds to the pseudo-instruction CLEAR R1, which sets R1 to 0. 2) What is the LC-3 assembly language instruction for this machine 3) True or False. LEA modifies the condition code bits. ) True or False. .END is an assembly language instruction. 5) True or False. HALT is actually a TRAP instruction. 6) Using operate type instructions only place the value 45 in RI . 7) True or False. In a Von Neumann machine data and instructions both reside in memory 8) What is the opcode for GETC in LC-3. i)True or False. In LC-3 all memory can be accessed with 16 bits. G) Give the decimal value for this 2's complement bit pattern0001 (k) Give the decimal number 119 as a number in base 5. (1) What is the range of values that can be represented with 16 bits in two's complement format.Explanation / Answer
1)AND R1,R1
2)LDR (Base+Address) where last 6 bits give offset and bits from 8-10 give base and 5-7 give destination.
Figure out answer yourself
3) False ,since lea just stores offset value to register there is no arithmetic going on so no flags will be affected.
4) False,.end is a pseudo operation it look like a instruction but opcode starts with dot.
5)True,Halt is a pseudo instruction for trap x25.
