Digital VLSI System Design seminar on processor basics

1. GUIDED BY PRESENTED BY
Dr.JS Baliger Mrs.Renuka N
Asst. Prof.,Dept of E&C 1TU19LVS11
DSDV SEMINAR ON
PROCESSOR BASICS

2. I N T R O D U C T I O N
The way instructions and data are encoded in binary and stored in memory

3. EMBEDDED COMPUTER ORGANIZATION

4. EMBEDDED COMPUTER ORGANIZATION
CPU : PROCESSES THE DATA ACCORDING TO THE PROGRAM
INSTRUCTION MEMORY : PROGRAM ENCODED IN BINARY FORM AND IS STORED IN INSTRUCTION
MEMORY
DATA MEMORY: DATA UPON WHICH THE PROGRAM OPERATES,WHICH IS IN BINARY FORM AND
STORED IN DATA MEMORY
ACCELERATOR: A SPECIAL CIRCUIT DESIGNED TO IMPLEMENT SPECIFIC PROCESSING OPERATIONS
WITH HIGHER PERFORMANCE
INPUT , OUTPUT & I/O CONTROLLER: ALLOWS THE COMPUTER TO AQUIRE DATA TO BE PROCESSD &
TO DELIVER THE RESULTS

5. EMBEDDED COMPUTER ORGANIZATION WITH
MULTIPLE BUSES

6. PROCESSOR CORES AND MICROCONTROLLERS

7. INSTRUCTIONS AND DATA LITTLE ENDIAN & BIG ENDIAN
Here, the CPU determines the
resources required to perform
the operation specified by the
instruction
In complex processors,
decode checks for resource
conflicts & availability of data
& waiting till resources are
free
Decode Execute
CPU has special register called
PC, in which the address of
the next instruction is fetched
in advance
Fetch
01 02 03
In the execute step, the
CPU activates the
appropriate internal
sources to perform the
operation .
CPU can execute several
instructions in parallel by
pipelining and superscalar
execution
