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]

Match the description to the instruction

Imagine in the PennSim simulator line 3 (address 0x321F) was highlighted yellow (line of code to be executed next). If we hit:    Step the next line highlighted would be [1]    If instead we hit Next the next line highlighted would be [2] If the current highlighted line was line 7 (address 0x3222) and we hit Next the next line highlighted would be [3]

Simulate different scenarios in your head, but in all scenarios assume condition check is eventually false Then give the best answer to the following: Shape A is [1] Shape B is [2] Shape C is [3] Shape E is [4]

To perform an LDI instruction the processor first [off_ext] and [addr_form] this result is [first_op].  The data [op] is then [2nd_op], and data returned is [final]
