Presentation Overview

• What is a SoC?
• Implementation Options
• Design
• Advantages
• Disadvantages
• TigerSHARC
• Future of SoCs
• Tolapai example

3
What is a SoC?

• Necessary components of a computer system
  embedded on a single silicon die.
• SiP System in a Package multiple die in a
  single package.
• SoP System on a Package multiple layers of
  discrete components

4

• A typical SoC will contain
• A processor
• Onboard execution memory (SRAM)
• Peripheral systems interfaces connected to the
  processing core via a SoC bus
• Many microcontrollers may contain FLASH memory
  for program storage

How is a SoC implemented?

• ASIC Application Specific IC, very integrated,
  yet very expensive
• FPGA Cheaper to implement, field reprogrammable
• Programmable Devices Off the shelf devices,
  quick to program, cheap.

7
SoC Design

• IP hardware blocks and software blocks developed
  in parallel
• Hardware in CAD
• Software in development environment
• Emulated and verified on FPGA
• Place and Route, created in silicon

SoC Advantages

• Decreased power consumption
• Increased reliability
• Smaller board space
• Can be cheaper when using ready to go components

10
SoC Disadvantages

• Extremely high design cost (for the actual chip)
• Large silicon space may be required
• Component testing may be difficult
• Prototyping may take longer
• Intellectual property (IP) issues

11
TigerSHARC

• TigerSHARC contains several SoC components
• Execution memory
• Processing Core
• Peripheral interface
• Link ports
• EBIU port
• JTAG port
• Ext. flags, timers, DMA, etc

Where are SoCs Headed?

• More tightly integrates SoCs will result in
  smaller electronic products that use less power,
  are faster, and more reliable
• Nano scale robots for fighting human diseases,
  curing diseases.

14
Intel Tolapai

• The XScale replacement is not a pure processor,
  but rather a tightly integrated SoC
• Does away with many supporting chips (North,
  South bridges as found in typical systems)
• Aimed at mobile devices market (PDAs, cell
  phones, etc)
