Our uDATAPATH_Collatz is a component that computes the Collatz Array Sequence for a given input number. The input and output are 8-bit vectors (data bus). The component is synchronous and has a reset signal to read the input data and perform the series calculation. The component implementation is based on a 4-register Datapath and ALU such that the implementation emulates basic assembler instructions programmed in a simple state machine.
To test the component, you must put a data on the input bus BB_SYSTEM_data_InBUS[7:0], activate the Reset signal. In the output bus BB_SYSTEM_data_OutBUS[7:0] you can see the calculated string. * The series will be calculated close to the clock rate. Visually you will not be able to see the intermediate data unless you use a probe reading per digital channel from an oscilloscope.
