Match the register name to its definition

To negate a 2’s comp number we [step1] then we [step2].  This procedure works for [works]. We use sign extension to transform a 2’s comp number into another that [SE_purpose].  To sign extend a 2’s comp number we [SE_meth].

 What statement can be made about these adders  

Match instruction types to their best definitions.

 ABC F  000  [f]  001   010  [1]  011   100   101  [2]  110   111  [3] For the function given fill in the 4 output values with dropdowns

What are all the input signals to this machine [1] Which signal(s) is/are output(s) of this machine [2] Which state(s) can the machine stay in for multiple consecutive clock cycles [3] How many flops are required to implement this machine [4]

Choose item(s) that represent ways in which the registers of a register file are used.

Use the dropdown to select the proper signal for each SigN connection shown in the diagram Sig1 = [sig1]    Sig2 = [sig2] Sig3 = [sig3] 

To perform the operation: R1

Use your LC-3 Programmer’s Reference to decode and evaluate the instruction being performed. The state of the LC-3 after FETCH is shown. The address that will be [1] is [2]
