Question

Consider the implementation of the Algorithmic State Machine (ASM) shown in Figure Q2.1. (a) Draw a schematic diagram of the datapath using the following components: registers, adders, multipliers, comparators, multiplexers and counters (with synchronous reset and increment inputs), as required. Clearly indicate all control signals in the diagram. reset wait $X \leftarrow \text{data}$ $N \leftarrow X$ $C \leftarrow 0$ $A \leftarrow \text{inpA}$ init TRUE $X = 0$ ? $Y \leftarrow \text{data}$ $C \leftarrow C + 1$ FALSE Figure Q2.1 [10 marks] mul $M \leftarrow X \times Y$ $X \leftarrow \text{data}$ acc $A \leftarrow A + M$ $C \leftarrow C + 1$ $Y \leftarrow \text{data}$ $C = N$ ?
