What are the instruction sets of 8086 microprocessor?
Microprocessor – 8086 Instruction Sets 1 Data Transfer Instructions 2 Arithmetic Instructions 3 Bit Manipulation Instructions 4 String Instructions 5 Program Execution Transfer Instructions (Branch & Loop Instructions) 6 Processor Control Instructions 7 Iteration Control Instructions 8 Interrupt Instructions
How does the number of rotates set in 8086 RCL?
The number of rotates is set by operand2. When immediate is greater then 1, assembler generates several RCL xx, 1 instructions because 8086 has machine code only for this instruction (the same principle works for all other shift/rotate instructions).
How can I get certificate of NPTEL exam?
Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Guwahati .It will be e-verifiable at nptel.ac.in/noc. Only the e-certificate will be made available.
When immediate is greater than 1 in 8086?
When immediate is greater then 1, assembler generates several RCL xx, 1 instructions because 8086 has machine code only for this instruction (the same principle works for all other shift/rotate instructions). shift all bits left, the bit that goes off is set to CF and previous value of CF is inserted to the right-most position.
What is C166 family instruction set?
C166 Family Instruction Set Introduction User’s Manual 1 V2.0, 2001-03 1 Introduction The Infineon C166 Family of 16-bit microcontrollers offers devices that provide various levels of peripheral performance and programmability.
How many bytes are in a C166 instruction?
All C166 Family instructions consist of 2 bytes or 4 bytes (single word or double word instruction). Figure 1 Instruction Format Representation MCD04931
What are the addressing modes of C166?
C166 Family Instruction Set Addressing Modes User’s Manual 132 V2.0, 2001-03 6 Addressing Modes The Infineon 16-bit microcontrollers provide a lot of powerful addressing modes for access to word, byte and bit data (short, long, indirect), or to specify the target address of a branch instruction (absolute, relative, indirect).
What is the difference between 8086 and 8088?
• The Intel 8088, released in 1979. • The processor used in the original IBM PC. • The 8086 gave rise to the x86 architecture which eventually became Intel’s most successful processors. 3. Features of Intel – 8086 microprocessor • It is a 16-bit microprocessor. • 8086 has a 20 bit address bus can access up to 220 memory locations (1 MB).
What is pipelining in 8086 microprocessor?
26. Architecture 8086 Microprocessor 26 Bus Interface Unit (BIU) A group of First-In-First-Out (FIFO) in which up to 6 bytes of instruction code are pre fetched from the memory ahead of time. This is done in order to speed up the execution by overlapping instruction fetch with execution. This mechanism is known as pipelining.
What is CX in 8086 microprocessor?
30. Architecture 8086 Microprocessor 30 EU Registers Counter Register (CX) Consists of two 8-bit registers CL and CH, which can be combined together and used as a 16-bit register CX. When combined, CL register contains the low order byte of the word, and CH contains the high-order byte.
