The forwarding unit in computational architecture has the role of forwarding data signals from one processing stage to another without storing the data in a register. This allows the data to be processed faster and more efficiently as it does not require the extra step of writing the data to a register and then reading it back again. The forwarding unit is responsible for detecting data dependencies between different processing stages and making sure that the correct data is forwarded to the correct processing unit. This helps to ensure that the processing is done correctly and in the correct order, which is essential for the overall performance and accuracy of the computational system.
