Digital Logic - Register Transfer Language

Design a digital circuit with RTL sentences that implements the equation y = 13 x - 2z + 8. You have available three registers (A, B & C) with access to data memory starting at address 0x0050. Memory' is accessed with the memory access register (MAR). The supported arithmetic and logic unit is shown in the table. Provide the RTL code that implements the circuit knowing that: x is stored in memory location 0x0055 z is stored in memory location 0x0065 y should be stored in memory location 0x0070 You cannot use any other operation not supported in the given table
