Study Notes
Number System Conversions
- Decimal number 2910 converts to binary 111012 through successive division by 2, yielding remainders of 1, 0, 1, 1, and 1.
- The process for converting binary 111012 back to decimal involves positional value multiplication: (1 × 24) + (1 × 23) + (1 × 22) + (0 × 21) + (1 × 20) equals 2910.
- Octal 258 converts to decimal by calculating ((2 × 81) + (5 × 80)), resulting in decimal 2110.
- Decimal 2110 can be converted to binary, resulting in binary 101012 using similar division steps as before.
Conversion Techniques
- Binary to octal conversion is done by grouping binary digits into sets of three (from the right) and converting each to its octal equivalent.
- Octal to binary conversion requires converting each octal digit into a three-digit binary number and combining them.
- Binary to hexadecimal involves grouping binary digits into sets of four and converting each group into a hexadecimal symbol.
- Hexadecimal to binary conversion entails converting each hexadecimal digit into a four-digit binary number.
Combinational Circuits
- Output of combinational circuits depends solely on current inputs, with no memory of previous states.
- Types of combinational circuits include adders, subtractors, decoders, encoders, multiplexers, and demultiplexers.
Half Adder
- A half-adder takes two binary inputs and provides two outputs: sum and carry.
- Logical expressions for half-adder:
- Sum = A⊕B
- Carry = AB
- Can be implemented using NAND or NOR gates.
Full Adder
- A full adder adds three 1-bit binary numbers (A, B, and C) with outputs for sum and carry.
- The main difference from a half-adder is the additional input.
- Requires two half-adders for implementation, utilizing nine universal gates (NAND/NOR).
Computer Components
- Komponents of a computer are divided into hardware (physical devices like CPU and storage) and software (programs like operating systems and applications).
- The functional units of a computer consist of input, memory, arithmetic logic unit (ALU), output, and control unit.
8086 Architecture
- 8086 architecture features a 16-bit ALU, 16-bit registers, segmented memory addressing, and overlapping instruction fetch and execution.
- Two main functional parts: Execution Unit (EU) and Bus Interface Unit (BIU) operate asynchronously, enhancing processing speed.
Execution Unit (EU)
- Informs the BIU of memory locations for instruction fetching and executes those instructions.
- Components include general purpose registers, ALU, flag register, instruction decoder, and control unit.
- Functions include fetching instruction opcodes, decoding, and performing arithmetic/logical operations.
Bus Interface Unit (BIU)
- Handles data and address transfer between the processor and memory/I/O.
- Computes addresses and fetches instruction codes, storing them in a FIFO register set known as the Queue register.
