Microprocessor Arithmetic Instructions

Save Try Share Edit. The zero flag is set if the result of the operation was 0. Cross Reference Interfacing Examples between Zarlink. Discontinued BCD oriented 4-bit Save to Collection Create your free account to use Collections Save and organize all 0885 images you need for your projects with Collections. Due to the regular encoding of the MOV instruction using nearly a quarter of the entire opcode space there are redundant codes to copy a register into itself MOV B,Bfor instancewhich are of little use, except for delays.

The can also be clocked by an external oscillator making opcodds feasible to use the in synchronous multi-processor systems using a system-wide common clock for all CPUs, or to pocodes the CPU to an external time reference such as that from a video source or a high-precision time reference. Create and organize Collections on the go with your Apple or Android device.

Unlike the it does not multiplex state signals onto the data bus, but the 8-bit data bus is instead multiplexed with the lower 8-bits of the bit address bus to limit the number of pins to Adding the stack pointer to HL is useful for indexing variables in recursive stack frames.


An improvement over the sheey that the can itself drive a piezoelectric crystal directly connected to it, and a built-in clock generator opcodew the internal high amplitude two-phase clock signals at half the crystal frequency a 6.

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.

For example, multiplication is implemented using a multiplication algorithm. More complex operations and other arithmetic operations must be implemented in software.

For two-operand 8-bit operations, the other operand can be either an immediate value, another 8-bit register, or a memory cell addressed by the bit register pair HL. A downside compared to similar contemporary designs such as the Z80 is the fact that the buses require demultiplexing; however, address latches in the Opxodes, and memory chips allow a direct interface, so an along with these chips is almost a complete system.

8085 Arithmetic Instructions

No abstract text available Text: The has extensions to support new interrupts, with three maskable vectored interrupts RST 7. Create a Free Account.

State signals are provided by dedicated bus control signal pins and two dedicated bus state ID pins named S0 and S1. This page was last edited on 16 Novemberat In other projects Wikimedia Commons.


Sign in to our Contributor sheef. Retrieved from ” https: Some of them are followed by one or two bytes of data, which can be an immediate operand, a memory address, or a port number.

The Intel ” eighty-eighty-five ” is an 8-bit microprocessor produced by Intel and introduced in All data, control, and address signals are available on dual pin headers, and a large prototyping area is provided. An immediate value can also be moved into any of the foregoing destinations, using the MVI instruction.

As in thethe contents of the memory address pointed to by HL can be accessed as pseudo register M. All three are masked after a normal CPU reset.

SIM and RIM also allow the global interrupt mask state and the three independent RST interrupt mask states to be read, the pending-interrupt states of those same three interrupts to be read, the RST 7.

Exceptions include timing-critical code and code that is sensitive to the aforementioned difference in the AC flag setting or differences in undocumented CPU behavior. The is a binary compatible follow up on the Two Emulator Probes are available: See AN for more information.

These instructions are written pocodes the form of a program which is used to perform various operations such as branching, addition, subtraction, bitwise logicaland bit shift operations. Editorial content, such as news and celebrity images, are not cleared for commercial use.
