Intel 8085Architecture - Instruction format addressing modes - Basic timing diagram - input/output - Interrupt system - 8085 based system design(Introduction only)6 - Bit Processors (Intel 8086 And Motorola 68000)Intel 8086: Architecture - addressing modes and Instruction format taking MOV destination, SRC instruction as example - interfacing of RAM to 8086 - odd and even addressed banks - storing/retrieval of 16 bit data at an odd address Motorola 68000 to be studied in comparison with 8086 - differences in, i. register array arrangement, ii. Memory Interfacing, iii. MOV instruction now is MOV source, destination iv. special signals like valid Memory Address and, v. only memory mapped I/O possible.MicrocontrollersIntel 8-bit and 16-bit microcontrollers - 8031 and 8096 suggested - compared to microprocessors the extra features available: i. On chip D/A and A/D facilities, ii. Watchdog timer, iii. Capability for bit-wise manipulation - real time clock - automatic process control / instrumentation applications case studies - cross assemblers.Interfacing BasicsOn controlling/monitoring continuous varying (analog) non-electrical signal using microprocessor/microcontrollers need for interfacing ICs - DIP switch - thumb wheel switch as input devices - single LED, seven segment LED as output devices - interfacing these using both memory mapped I/O and peripheral mapped I/O - D/A, A/D ICs and their signals - sample and hold IC and its usage.Interfacing Ic s 8255 - Programmable peripheral Interface along with 8085 - Both Mode 0 and Mode 1, detailed study.8254 - Programmable Interval Timer along with Intel 8086 - Both Mode 0 and Mode 3 to be studied.Need for the following ICs: (a) 8251 - USART; (b) 8257 - Direct Memory Access Controller; (c) 8259 - Programmable Interrupt Controller; (d) 8279 - Keyboard / Display Interface.
