Explain Different Types of Memory Models Used in 8086
To store more than 8 bits we have to use two registers in pairs. The four major ways of passing parameters to and from a procedure are. Programming Model 8086 8086 Microprocessor Care4you This directive is used for the purpose of allocating and initializing single or multiple data bytes. . DW The DW directive is used to declare a WORD type variable A WORD occupies 16 bits or 2 BYTE. Stack Segment Register SS. The address bus is of 20 bits. Default data access is from DS. Is used for addressing stack segment of the memory. Passing parameters using pointers. Immediate addressing mode-In this mode the operand is specified in the instruction itself. This technique is called as parameter passing. Instructions are longer but the operands are easily identified. Explain the two types of conditional jumps. This mode is very fast as compared to others because CPU doesnt need to access memory. All op...
