Study Notes
Microprocessor Architecture
- The 8086 microprocessor has a 16-bit data bus.
- The 8088 microprocessor can directly access 2^20 (1,048,576) memory locations.
Drawbacks of Multiplexed Bus
- The multiplexed address and data bus in the 8086 microprocessor is a drawback because it reduces the speed of operation.
Registers
- The 8086 microprocessor provides 14 16-bit registers.
Input/Output Operations
- The 8086 microprocessor can directly access 8-bit and 16-bit I/O ports.
Operating Modes
- The Intel 8086 supports two modes of operation: real mode and protected mode.
Performance Measurement
- The measure of the number of instructions executed per unit time is called instruction throughput or clock speed.
Bus Interface Unit (BIU)
- The Bus Interface Unit (BIU) of 8086 provides a buffer to hold the instructions and data temporarily.
- The instruction queue in the Bus Interface Unit (BIU) holds the next few instructions to be executed, allowing for faster processing.
Registers
- A register in a computer processor holds a value or a sequence of values that can be used for computational purposes.
