System On Chip - SoC
[attachment=27654]
Introduction
Technological Advances
today’s chip can contains 100M transistors .
transistor gate lengths are now in term of nano meters .
approximately every 18 months the number of transistors on a chip doubles – Moore’s law .
The Consequences
components connected on a Printed Circuit Board can now be integrated onto single chip .
hence the development of System-On-Chip design .
What is SoC ?
The VLSI manufacturing technology advances has made possible to put millions of transistors on a single die. It enables designers to put systems-on-a-chip that move everything from the board onto the chip eventually.
People B:
SoC is a high performance microprocessor, since we can program and give instruction to the uP to do whatever you want to do.
People C:
SoC is the efforts to integrate heterogeneous or different types of silicon IPs on to the same chip, like memory, uP, random logics, and analog circuitry.
All of the above are partially right, but not very accurate!!!
System on Chip interconnection
Design reuse is facilitated if “standard” internal connection buses are used .
All cores connect to the bus via a standard interface .
Any-to-any connections easy but …
Not all connections are necessary .
Global clocking scheme .
Power consumption .
Standardization is being addressed by the Virtual Socket Interface Alliance (VSIA)
System on Chip cores
One solution to the design productivity gap is to make ASIC designs more standardized by reusing segments of previously manufactured chips.
These segments are known as “blocks”, “macros”, “cores” or “cells”.
The blocks can either be developed in-house or licensed from an IP company.
Cores are the basic building blocks .
The Benefits
There are several benefits in integrating a large digital system into a single integrated circuit .
These include
Lower cost per gate .
Lower power consumption .
Faster circuit operation .
More reliable implementation .
Smaller physical size .
Greater design security .
