Operation Principle

• CU broadcasts instruction to all processors.

  Single program executed by processor array.

• Each ALU executes instruction on local data
  • arithmetic/logic,
  • read/store data from/on host,
  • transfer data through network.
• CU may select by bitmask subset of processor array for execution.

  Conditional execution.
