Which number system is used for addressing?

number addressing (NA) is the Internet addressing system which is similar to letter addressing system.


What is Direct Addressing in computer systems architecture?

Direct Addressing in computer systems architecture is when the number in the address field of the instruction is the actual memory address to be accessed.

How do you address a letter to Argentina?

When addressing a letter to Argentina, you will need to first write the name of the recipient on the top line of the address. From there, simply write the house number and street name on the following line. Lastly, add the city, province and zip.


What is number addressing system?

Every TCP/IP network requires a unique network number and every host on TCP/IP requires a unique IP address. The system that takes care of this is called number addressing system.


What facts go into determining the use of the addressing bits of an instruction?

Following facts determine the use of addressing bits of an instruction: Number of addressing modes: Sometimes an addressing mode can be indicated implicitly. In other cases, the addressing modes must be explicit, and one or more mode bits will be needed. Number of operands: Typical instructions on today's machines provide for two operands. Each operand address in the instruction might require its own mode indicator, or the use of a mode indicator could be limited to just one of the address fields. Register versus memory: The more that registers can be used for operand references, the fewer bits are needed. Number of register sets: One advantage of using multiple register sets is that, for a fixed number of registers, a functional split requires fewer bits to be used in the instruction. Address range: For addresses that reference memory, the range of addresses that can be referenced is related to the number of address bits. Because this imposes a severe limitation, direct addressing is rarely used. With displacement addressing, the range is opened up to the length of the address register. Address granularity: In a system with 16- or 32-bit words, an address can reference a word or a byte at the designer's choice. Byte addressing is convenient for character manipulation but requires, for a fixed-size memory, more address bits.


How do you xxplain the types of memories?

Each instruction of a computer specifies an operation on certain data. The are various ways of specifying address of the data to be operated on. These different ways of specifying data are called the addressing modes. The most common addressing modes are:Immediate addressing modeDirect addressing modeIndirect addressing modeRegister addressing modeRegister indirect addressing modeDisplacement addressing modeStack addressing modeTo specify the addressing mode of an instruction several methods are used. Most often used are :a) Different operands will use different addressing modes.b) One or more bits in the instruction format can be used as mode field. The value of the mode field determines which addressing mode is to be used.The effective address will be either main memory address of a register.Immediate Addressing:This is the simplest form of addressing. Here, the operand is given in the instruction itself. This mode is used to define a constant or set initial values of variables. The advantage of this mode is that no memory reference other than instruction fetch is required to obtain operand. The disadvantage is that the size of the number is limited to the size of the address field, which most instruction sets is small compared to word length.INSTRUCTIONOPERANDDirect Addressing:In direct addressing mode, effective address of the operand is given in the address field of the instruction. It requires one memory reference to read the operand from the given location and provides only a limited address space. Length of the address field is usually less than the word length.Ex : Move P, Ro, Add Q, Ro P and Q are the address of operand.Indirect Addressing:Indirect addressing mode, the address field of the instruction refers to the address of a word in memory, which in turn contains the full length address of the operand. The advantage of this mode is that for the word length of N, an address space of 2N can be addressed. He disadvantage is that instruction execution requires two memory reference to fetch the operand Multilevel or cascaded indirect addressing can also be used.Register Addressing:Register addressing mode is similar to direct addressing. The only difference is that the address field of the instruction refers to a register rather than a memory location 3 or 4 bits are used as address field to reference 8 to 16 generate purpose registers. The advantages of register addressing are Small address field is needed in the instruction.

The address field of the instruction refers to a register. The register contains the effective address of the operand. This mode uses one memory reference to obtain the operand. The address space is limited to the width of the registers available to store the effective address.Displacement Addressing:In displacement addressing mode there are 3 types of addressing mode. They are :1) Relative addressing2) Base register addressing3) Indexing addressing.This is a combination of direct addressing and register indirect addressing. The value contained in one address field. A is used directly and the other address refers to a register whose contents are added to A to produce the effective address.Stack Addressing:Stack is a linear array of locations referred to as last-in first out queue. The stack is a reserved block of location, appended or deleted only at the top of the stack. Stack pointer is a register which stores the address of top of stack location. This mode of addressing is also known as implicit addressing.Read more: http://wiki.answers.com/Explain_the_different_types_of_addressing_modes_in_8085_microprocessor.#ixzz1VB4Smbt3
