Systolic Arrays (contd.)

• Practical realizations (e.g. iWARP) use quite general processors
  • Enable variety of algorithms on same hardware
• But dedicated interconnect channels
  • Data transfer directly from register to register across channel
• Specialized, and same problems as SIMD
  • General purpose systems work well for same algorithms (locality etc.)

Example: Systolic array for 1-D convolution
