In data flow path part the functional units include ALU, buses for interconnection, registers, multipliers etc. A digital circuit is generally defined as to contain data flow part and control flow part. Moreover, serial ALU is planned to be used in 3DWT processor to achieve some encouraging results for future research. Our approach is to introduce a new method to control all arithmetic and logic manipulations by appending Finite state Machine (FSM) after careful investigation regarding timing cycles and control signal constraints. Although serial operation makes the process slow but reduces the number of components and power consumption in design. Serial ALU is also used as a programmable array for sequence analysis. ![]() The application of serial operations in digital system is to develop high performance Field Programmable VLSI Processor (FPVLSI). ![]() Serial ALU with finite state machine is introduced by Kamran and Feng. Serial ALU designed shows optimization in components utilization, in switching actions to justify its use in processors designed for image processing task as it causes not only area reduction but also power dissipation is minimized.
