Opcode Sheet for 8085 Microprocessor With Description

Software simulators are available for the microprocessor, which allow simulated execution of opcodes in a graphical environment. Adding HL to itself performs a bit arithmetical left shift with one instruction.

Lastly, the carry flag is set if a carry-over from bit 7 of the accumulator the MSB occurred. The CPU is one part of a family of chips developed by Intel, for building a complete system. Trainer kits composed of a printed circuit board,and supporting hardware are offered by various companies. A surprising number of spare card cages and processors were being sold, leading to the development of the Multibus as a separate product.

Intel 8085

Operations that have to be implemented by program code subroutine libraries include comparisons of signed integers as well as multiplication and division. Pin 39 is used as the Hold pin. Many of these support chips aheet also used with other processors. One sophisticated instruction is XTHL, which is used for exchanging the register pair HL with the value stored at the address indicated by the stack pointer.


Also, the architecture and instruction set of the are easy for a student to understand. The Intel ” eighty-eighty-five ” is an 8-bit microprocessor produced by Intel and introduced in It can also accept olcodes second processor, allowing a limited form of multi-processor operation where both processors run simultaneously and independently.

The contents of register H are exchanged with the contents of register D, and the contents of register L are exchanged with the contents of register E. The is a binary opcods follow up on the The parity flag is set according to the parity odd or even of the opcoes.

Retrieved 31 May It is a large and heavy desktop box, about a 20″ cube in the Intel corporate blue color which includes a CPU, monitor, and a single 8-inch floppy disk drive.

Views Read Edit View history. The incorporates the functions of the clock generator and the system controller on chip, increasing the level of integration. Share Collections to anyone by email or to other Shutterstock users. State signals oocodes provided by dedicated bus control signal pins and two dedicated bus state ID pins named S0 and S1.


The instruction stores bit data into shwet register pair designated in the operand. You can redownload your image for free at any time, in any size.

The contents of the register or the memory are subtracted from the contents of the accumulator, and the result is stored in the accumulator. The same is not true of the Z Shete have an account?

No abstract text available Text: The has extensions to support new interrupts, with three maskable vectored interrupts RST 7. Adding the stack pointer to HL is useful for indexing variables in recursive stack frames.

Cross Reference Interfacing Examples between Mitel. Like larger processors, it has CALL and RET instructions for multi-level procedure calls and returns which can be conditionally executed, like jumps and instructions to save and restore any bit register-pair on the machine stack. The later iPDS is a portable unit, about 8″ x 16″ x 20″, with a handle.
