Simulate the following code in your head.  Then answer the questions posed. This code performs [Alg] When finished R1 will contain [R1] The last 9-bits of the “BR LOOP” instruction are: [offset] Are there any clues that this code was intended to work with the lc3os? [lc3os]    

What is the capacity of a memory with 3 address bits and 4-bit data words. (simply enter a number for the number of bits)

The most negative number an LC-3 operand can be is: [1] Operands stored in registers can be considered to be [2] The most positive an immediate LC-3 operand can be is [3]  

If the last instruction executed was an ADD that resulted in x0C1D, which of the following branch instructions would be taken BRnz [BRnz] BRnp [BRnp] BRzp [BRzp] BR [BR]

A memory has 6 address bits and a data word size of 4-bits: The total capacity is [1] The number of words is [2] An appropriate name for its data output would be [3]

; Routine takes max of two arguments (R0,R1) returns in R0 ; R0 = Argument 1 ; R1 = Argument 2 ;  Computes the max of R0 and R1 and places it in R0 MAX  [1]                          ; negate R1               [2]               [3]                                      ; compare R0 to R1              [4]                                     ; decide based on comparison              [5] DONE  RET This routine is [6]

Simulate this code in your head Register R1’s purpose is best described as [1] Register R0’s purpose is best described as [2] The value in register R3 is [3] This algorithm implements [4]  This algorithm does not work when Var2 is negative or zero.  It work when Var1 is: [5]  

Why don’t we use BR to call a subroutine?  [1] The RET instruction is an alias for [2]  

Choose the best description of the LEA instruction as used in LC-3 assembly

Complete the symbol table for the following code: Label: Address: START [1] [2] [3] [4] [5] [6] [7]
