An 8-bit microprocessor can process 8-bit data at a time. The word length ranges from 4 bits to 64 bits depending upon the type of the microcomputer. Data Types − The microprocessor has multiple data type formats like
binary, BCD, ASCII, signed and unsigned numbers
.
What is instruction format in 8085 microprocessor?
An instruction is
a command to the microprocessor to perform a given task on a specified data
. Each instruction has two parts: one is task to be performed, called the operation code (opcode), and the second is the data to be operated on, called the operand.
What is instruction and data format?
An instruction (instruction format) is
a command to the microprocessor to perform a given task on a particular data
. Each instruction (instruction format) is of two parts. One is to be performed, called the operation code or opcode and the second one is the data to be operated on, called the operand.
What is the use of data in microprocessor?
A microprocessor accepts
binary data as input, processes that data, and then provides output based on the instructions stored in the memory
. The data is processed using the microprocessor’s ALU (arithmetical and logical unit), control unit, and a register array.
How an instruction and data are formatted for instructions?
The format of a typical instruction is composed of two parts:
an operation code or op-code and an operand
. Every instruction needs an op-code to specify what the operation of the instruction is and then an operand that gives the appropriate data needed for that particular operation code.
What are 5 types of instruction operations?
- Data handling and memory operations.
- Arithmetic and logic operations.
- Control flow operations.
- Coprocessor instructions.
- Number of operands.
What are different data formats?
Recommended Digital Data Formats:
Text, Documentation, Scripts:
XML, PDF/A, HTML, Plain Text
. Still Image: TIFF, JPEG 2000, PNG, JPEG/JFIF, DNG (digital negative), BMP, GIF. Geospatial: Shapefile (SHP, DBF, SHX), GeoTIFF, NetCDF.
Is 3 Byte A instruction?
Three-byte instructions –
Three-byte instruction is the
type of instruction in which the first 8 bits indicates the opcode and the next two bytes specify the 16-bit address
. The low-order address is represented in second byte and the high-order address is represented in the third byte.
What microprocessor consists of?
Microprocessor consists of
an ALU, register array, and a control unit
. ALU performs arithmetical and logical operations on the data received from the memory or an input device.
What are the features of 8085 microprocessor?

What is microprocessor example?
Examples of: CISC are
Intel 386, Intel 486, Pentium, Pentium Pro, Pentium II
, etc. RISC are IBM RS6000, DEC Alpha 21064, DEC Alpha 21164, etc. EPIC is IA-64 (Intel Architecture-64), etc.
What is Ram in memory?
Random access memory
(RAM) is a computer’s short-term memory, which it uses to handle all active tasks and apps.
Does microprocessor have memory?
There are two basic kinds of memory used in microprocessor systems – commonly called
Read Only Memory and Read / Write Memory
, but more usually called ROM and RAM – “Read Only Memory” and “Random Access Memory”. … Storing these in ROM means they always available, even when the computer has only just been switched on.
What is instruction with example?
The definition of instruction is the act of educating, giving the steps that must be followed or an order. An example of instruction is
someone giving another person detailed directions to the library
. noun.
What are the types of instruction set?
- Reduced Instruction Set Computer (RISC)
- Complex Instruction Set Computer (CISC)
- Minimal instruction set computers (MISC)
- Very long instruction word (VLIW)
- Explicitly parallel instruction computing (EPIC)
- One instruction set computer (OISC)
- Zero instruction set computer (ZISC)
Where is instruction set stored?
An instruction, stored
in the memory
, is fetched into the control unit by supplying the memory with the address of the instruction. The control unit decodes the instruction in order to find the sequence of operation necessary to execute it.
