    Adrive2 Advance Computer Architectuer CS501 FALL 2010 second assignment solution

    Sponsored Links1


    What will be the logic levels on the external SRC buses when each of the given SRC instruction is executing on the processor? Complete Table: A all numbers are in the decimal number system, unless noted otherwise. (Assume the required missing information if necessary). Also Specify memory addressing modes for each of the SRC instructions given in Table.


    SRC instruction
    RTL Equivalent
    Address Bus<31.0>
    Data Bus
    <31.0>
    MRead
    MWrite
    Addressing mode
    Ld r9,4(r2)






    Ld r4,4






    Ld r3, M[r3]






    Move r3, r2






    Table: A


    Assumptions:


    • All memory content is aligned properly.
    • In other words, all the memory accesses start at addresses divisible by 4.
    • Value in the PC = 000DC348h

    Memory map with assumed values


    Register map with assumed values

    SRC instruction RTL Equivalent Address Bus<31….0> Data Bus
    just for reference.

    <31….0> MRead MWrite Addressing mode
    Ld r9,4(r2) R9 4xR2 Displacement
    Ld r4,4 R4 M[4] Direct
    Ld r3, M[r3] R3 M[R3] Register
    Move r3, r2 R3 R2 unknown ???? 1 1 Register
