Advanced Microprocessors

The 8086 microprocessor has a 20-bit address bus, which allows it to address up to 2²⁰ = 1 MB (1,048,576 bytes) of physical memory. However, the internal registers of 8086 are only 16-bit wide, which can directly address only 2¹⁶ = 64 KB. To resolve this, t...

Pipelining is a technique in which the execution of multiple instructions is overlapped in time. Instead of completing one instruction fully before starting the next, different stages of different instructions are executed simultaneously, improving overall ...

A descriptor is a data structure (8 bytes long) stored in memory that contains all the necessary information about a memory segment. In the protected mode of the 80286 microprocessor, segment registers do not hold the physical base address directly; instead...

A descriptor is an 8-byte (64-bit) data structure stored in memory that defines and describes the characteristics of a memory segment in the 80286 microprocessor's protected mode. It contains all the information the processor needs to access and protect a s...

--- An addressing mode refers to the way in which the operand (data) of an instruction is specified. The 8086 microprocessor supports the following addressing modes: --- - The operand (data) is directly specified in the instruction itself. - The data follow...

--- An addressing mode refers to the way in which the operand (data) of an instruction is specified or accessed. It defines how the CPU locates the data it needs to process. --- The operand (data) is directly specified in the instruction itself. No memory a...

Multitasking is the ability of a processor to execute multiple tasks (programs) concurrently by rapidly switching between them. In the 80286, multitasking capability is improved by adding necessary memory management and task switching mechanisms in such a w...

--- --- The 80286 microprocessor is internally divided into four functional sub-units that operate in a pipelined fashion to improve performance: --- - The Bus Unit is responsible for all external bus operations. - It manages the 24-bit address bus and the ...

The Intel 80286 is a 16-bit microprocessor introduced by Intel in 1982. It is an advanced version of the 8086/8088 microprocessors. It has a 16-bit data bus and a 24-bit address bus, which allows it to address up to 16 MB of physical memory. It can operate ...

--- Harvard Architecture is a computer design model in which separate memory and separate buses are used for instructions (program) and data. This is in contrast to the Von Neumann architecture, where a single memory and single bus are shared for both instr...

In Protected Mode of the 80286/80386 microprocessor, memory access is managed through a structure called the Global Descriptor Table (GDT). The segment registers no longer hold base addresses directly; instead, they hold selectors that point to descriptors ...

Paging is a memory management mechanism used in protected mode that allows handling of large segments of memory by dividing them into fixed-size units called pages. Each page is of 4K bytes (4096 bytes) in size. - The paging unit is a memory management unit...
