Control unit (cu)-array processing, Computer Engineering

Control Unit (CU) : Every PEs are under the control of one control unit. CU controls the inter communication among the PEs. There is a local memory of CU also known as CY memory. The user programs are loaded into the CU memory. The vector instructions in the program are broadcast to the array of PEs and decoded by CU. Instruction decoding and fetching is done by the CU only.
