14. What is SoC ?
SoC not only chip, but more on “system”.
SoC = Chip + Software + Integration
The SoC chip includes:
Embedded processor
ASIC Logics and analog circuitry
Embedded memory
The SoC Software includes:
OS, compiler, simulator, firmware, driver, protocol stack Integrated
development environment (debugger, linker, ICE)Application interface
(C/C++, assembly)
The SoC Integration includes :
The whole system solution
Manufacture consultant
Technical Supporting

Gap in Current Technology Demand and Supply

16. 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 .

38. 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 .
– Can be cheaper when using ready to go components
i.e. reusable IPs
38

39. The Drawbacks
• The principle drawbacks of SoC design are
associated with the design pressures imposed
on today’s engineers , such as :
– Time-to-market demands .
– Exponential fabrication cost .
– Increased system complexity .
– Increased verification requirements .

40. MAJOR SOC APPLICATIONS
 Speech Signal Processing .
 Image and Video Signal Processing .
 Information Technologies
 PC interface (USB, PCI,PCI-Express, IDE,..etc)
Computer peripheries (printer control, LCD monitor
controller, DVD controller,.etc) .
 Data Communication
 Wireline Communication: 10/100 Based-T, xDSL,
Gigabit Ethernet,.. Etc
 Wireless communication: BlueTooth, WLAN,
2G/3G/4G, WiMax, UWB, …,etc
40

41. SUMMARY
 Technological advances mean that complete
systems can now be implemented on a single
chip .
 The benefits that this brings are significant in
terms of speed , area and power .
 The drawbacks are that these systems are
extremely complex requiring amounts of
verification .
 The solution is to design and verify re-useable IP
