Intel 8088 (8086) Microprocessor Structure
What are microprocessor-based systems?
Microprocessor-based systems are electrical systems consisting of microprocessors, memories, I/O units, and other peripherals.
Microprocessors are the brains of the systems
Microprocessors access memories and other units through buses
The operations of microprocessors are controlled by instructions stored in memories
What are microprocessors?
A microprocessor is a processor (or Central Processing Unit, CPU) fabricated on a single integrated circuit.
Evolution of Computers
First generation (1939-1954) - vacuum tube
Second generation (1954-1959) – transistor
Third generation (1959-1971) - IC
Fourth generation (1971-present) - microprocessor
Other Commercial Microprocessors
PowerPC (IBM, Motorola)
Athlon, Dulon, Hammer (AMD)
Crusoe (Transmeta)
SPARC, UltraSPARC (Sun Microsystems)
TI’s TMS DSP chips (Texas Instruments)
StarCore (Motorola, Agere)
ARM cores (Advanced RISC Machines)
MIPS cores (MIPS Technologies)
Applications of Microprocessor-Based Systems
Computers
System performance is normally the most important design concern
