Question

name three types of address used in the von neumann architecture?

Answer 1

Answer:

•Registers. Registers are high speed storage areas in the CPU. ...

•Arithmetic and Logic Unit (ALU) The ALU allows arithmetic (add, subtract etc) and logic (AND, OR, NOT etc) operations to be carried out.

•Control Unit (CU)

Answer 2

The three types of addresses used in the von neumann architecture are Direct address, Indirect address, and Register address.

• The address portion of the instruction is equal to the effective address in the direct address mode. The address of the operand, which would be stored in memory, is directly provided by the address field of the instruction. In a branch-type instruction, the address field would specify the actual branch address.
• An indirect address is a location's symbolic, absolute, or relative address that also contains another address. To indicate a corresponding number of levels of indirect addressing, an indirect address must be followed by one or more indirection symbols.
• Indexing into the array of constant registers is made simple by the design of address registers. The operand is put in either an 8 bit or 16 bit general purpose register when using register addressing.
