The Memory unit has a capacity of 4096 words, and each word contains 16 bits.<\/strong><\/p>\n

    \n
  1. Data Register (<\/strong>DR)<\/strong> contains 16 bits which hold the operand read<\/strong> from the memory location.<\/li>\n
  2. Memory Address Register (<\/strong>MAR)<\/strong> contains 12 bits which hold the address for the memory location.<\/li>\n
  3. Program Counter (<\/strong>PC)<\/strong> also contains 12 bits which hold the address of the next instruction<\/strong> to be read from memory after the current instruction is executed.<\/li>\n
  4. Accumulator (<\/strong>AC)<\/strong> register is a general purpose processing register.<\/li>\n
  5. Instruction register (<\/strong>IR)<\/strong> is placed in the Instruction read from memory.<\/li>\n
  6. Temporary Register (<\/strong>TR)<\/strong> is used for holding the temporary data during the processing.<\/li>\n
  7. Input Registers (<\/strong>IR)<\/strong> holds the input characters given by the user.<\/li>\n
  8. Output Registers (<\/strong>OR)<\/strong> holds the output after processing the input data.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
