The instruction set is a collection of Instructions of Microprocessor, that determines what 4.Branch Group Instruction set of 8085. The Branch Instructions are the most powerful In this case, the sequence of the program returns to the main program if the condition is met and at this time Timing Diagram of 8085 Microprocessor. The instruction set of 8085 microprocessor architecture is nothing but instruction codes used to achieve an exact task, and instruction sets are categorized into various types namely control, logical, branching, arithmetic, and data transfer Instruction Set of 8085. — An instruction is a binary pattern designed inside a microprocessor to perform a specific function. — The entire group of instructions that a microprocessor supports is called Instruction Set. — 8085 has 246 instructions. In the 8085, an instruction cycle may consist of 1 to 6 machine cycles. • The µP operates with Each clock cycle is called a T state and a collection of several T states gives a machine cycle. • TIMING AND STATE DIAGRAM I/O write Cycle: summery: Delay routine process: A delay routine is If microprocessor has 5 MHz clock then internal clock frequency = 5/ 2 = 2.5 MHz Time for one T-state 8085 Microprocessor. Microprocessors and Microcontrollers/Architecture of Microprocessors. Overview of 8085 microprocessor ? 8085 Architecture • Pin Diagram • Functional Block Diagram. CALL instruction (3 byte instruction). The processor calls the subroutine, address of which is 5.3 Instruction Set of 8085 Microprocessor. 5.4 Timing Diagram for 8085 Instructions. 5.4.1 Timing Diagram of MOV reg, M. of instructions in the form of binary pattern called a machine language. However, it is. difficult for human beings to communicate in the language of 0s and 1s. 5. Programming model of 8085 microprocessor 6. Addressing modes. 7. Instruction set classification. The microprocessor uses this register to sequence the execution of the instructions. The function of the program counter is to point to the memory address from which the next byte is to 8085 Instructions: (1)Arithmetic Instruction. There are some of the important instructions in 8085 microprocessor. 1. ADD: - The content of operand are added to the content of the accumulator and the result is stored in Accumulator. Explain PIN diagram of 8051. Timing Diagram 8085 Microprocessor A timing diagram of a microprocessor depicts graphically the activities that are taking place at different As discussed previously, microprocessor fetches an instruction from the memory, decodes it, fetches the operands if required and then executes the 8085 is an 8-bit microprocessor as it operates on 8 bits at a time and is designed with N-MOS technology. In this article you will get to know about the definition This microprocessor exhibits some unique characteristics and this is the reason it still holds popularity among the microprocessors. Fig: 8085 flag register. Flags are flip-flops which are used to indicate the status of the accumulator and other The two internal registers W and Z are used to hold 8-bit data during the execution of some instructions, CALL and XCHG instructions. Timing Diagram for Memory Read Machine Cycle. 12 Timing diagram for the IN instruction. 7. 8085 INTERRUPTS. Interrupt Structure 8085 instruction set includes eight software interrupt instructions called Restart (RST) instructions. These are one byte instructions that make the processor execute a subroutine at predefined 12 Timing diagram for the IN instruction. 7. 8085 INTERRUPTS. Interrupt Structure 8085 instruction set includes eight software interrupt instructions called Restart (RST) instructions. These are one byte instructions that make the processor execute a subroutine at predefined This page of 8085 microprocessor tutorial describes 8085 microprocessor programming.It also Instruction Set Classification. Instruction is a binary pattern designated inside microprocessor to EXAMPLES: Jump, Call, Return etc. • Machine Control Operations: These instructions are used to Roughly where they're shown on the diagram. But that's just to give you a general idea -- if you want to know where they actually occur, get your hands on a board and look with an oscilloscope. I mean do the various registers used in 8085 are edge-triggered or level-triggered? That is immaterial, unless you're
