Advanced Microprocessors and Microcontrolers

1. INTRODUCTION
The Invention of the microprocessor has had a
profound impact on many aspects of our lives,

2. SYSTEM BLOCK DIAGRAM
 Any microprocessor based system must of necessary,
have some standard element such as memory, timing
and I/O devices

6. PENTIUM FEATURES
1.Wider Data Bus Width
(64 Bits  Improver the data transfer rate)
2. Fast Flouting Point Unit
(Fastest algorithms provide up to 10 times speed-up)
3. Improved Cache Structure
(Separate code and data caches integrated on-chip)
(Each cache is 8 Kbyte size with 32byte line size)
(It is two way set associative)
(Each cache has dedicated TLB to translate linear
addresses to psychical addresses)
4. Dual Integer Processor
(It allows execution of two instructions per clock)
5. Branch Prediction Logic
(To check whether a branch will be valid or not)
