The Registers component is a simple 16-bit register file. Ae and Be choose which register is routed to the A and B outputs. ALU is the input from the ALU. ALUe chooses which register to write. A register will only be written if W (write enable) is high.

R is a reset input and is optional. The R input (reset) sets all registers to zero.

The register file latches in the ALU result on the clock leading edge and sets the register on the clock trailing edge.

During operation, the contents of the registers are displayed and the current configurations of Ae, Be, ALUe, and W are indicated by lines the connect ALU to a register and registers to A and B.
