Type of Microprocessor :
Microprocessors fall into 3 categories:
The general purpose microprocessor have ALU with 1 or more then 1 registers which functioned as, a control unit, accumulator ,an instruction decoder which handled a fixed instruction set special and general purpose registers which varied significantly from microprocessor to microprocessor. A microprocessor can have an internal stack of fixed length or use external memory for stack. The general purpose microprocessor is available of word lengths of 16, 32, 16, 8, 4, and 1 bit.
The Bit slice microprocessor divide the functions of ALL, special purpose and general purpose registers and control unit into many ICs. For this ALU and general purpose registers were packed in separately from controls. Each register of ALU (RALU) package was really equivalent to 2 or 4-bit wide slice of registers and the ALU of the microprocessor. Bit slice processor might be cascaded to produce any unconventional or conventional word length of the microprocessor such as 4, 8, 10, 12, 16, 32 or higher bits. The control portion of bit slice processor was constructed from microprocessor sequencer IC and other logics.

Display control 8279 provides a 16 byte display memory and refresh logic. Every address in the display memory corresponds to a display unit with address zero represen
DMA controller : Steps include in transferring a block of data from I/O devices (for example a disk) to memory: 1. CPU sends a signal to initiate disk transfe
INT N : Interrupt Type N:- In the interrupt structure of 8086/8088, 256 interrupts are distinct equivalent to the types from OOH to FFH. When an instruction INT N is executed,
The definitions of the bits in ICWI are following: Always set to the value 1. It directs the received byte to ICWI as oppose to OCW2 or OCW3. Which also utilize the even addr
Could I get an estimate on how much it would cost to write a program in assembly language?
Maximim and Minimum mode 8088 system : In the maximum mode, the pin 880 is lastingly high. The functions and timings of other pins of 8088 are exactly similar to 8086. Due to t
Pin diagram of 8088 : The pin diagram of 8088 is shown in given figure. Most of the 8088 pins and their functions are exactly similar to the corresponding pins of 8086. Hence
