DATA SYSTEM PROCESSOR
Data system processors divided in two steps • It provides control signals
• They comes before data processorsControllers
• It process the data according to control signals
• They are connected to outputData

Design of digital system:-It is divided in two steps 1. data processor design (DPD) 2. Controller design (CD)
It designed with digital components.
DPD includes design of main system.
Designer should know working & need s of a system.
Example – Water level controller.
Parameters to consider for design issues.
1 Cost – It should be economic.
2 Efficiency – Should have low response time
3 Reliability – Should be reliable

CONTROLLERSThey are generally state machines.They are designed for data processor considering all signals that give information about staus of data processor.It uses ROM ,counter or any combinational logic with F/Fs.
