Program Plan Intro

Masked Move (MVM) instruction:

  • MVM instruction refers to a word instruction.
  • It is used to move data from source to destination and allows a portion of destination data to be masked by a separate word.
  • The function of MVM instruction is almost similar to that of MOV instruction, except that a masked move allows the data to be filtered out which is not required to be moved.

Terms used:

The following terms are used in the instruction

  • Source
    • Source refers to the address of the piece of data that is used in the instruction.
  • Destination
    • Destination refers to the address where the results of the instruction are stored.
  • Mask
    • Mask refers to the address of the mask through which the instruction moves the required data.
    • The mask can be either a constant value or hexadecimal value.

Registers in RISC-V are 64-bit.  For the sake of simplicity, consider the following instructions operating on 32-bit registers.  Assume that registers x5 and x6 hold the values 0xBBBBBBBB and 0x00000000, respectively. What is the value in x6 for the followingslli x6, x5, 6 Using the result from the part above, what is the value in x6 for the following instruction.            srli x6, x6, 6

There is an application that requires the following hardware: an Intel 8031, a Program ROM of 8Kx8, a Data ROM of 4Kx8 for look-up tables and a Data RAMs of 8Kx8. The memory map of the design: Program ROM should start at address 0000H. Then, the Data ROM should come above the Program ROM. Finally the Data RAM must go to the top of the memory map. There should be no gaps between the memory addresses of the external ROMs.  Calculate the address space of the ROMs and RAMs of your design.
