Here is an example of how you could implement the architecture "tt" of the sineWaveGenerator module in Verilog:
```
module sineWaveGenerator (
input clk,
input rst,
output reg signed [15:0] sineOut
);
reg signed [15:0] sineTable[0:99];
reg [7:0] addr;
initial begin
// Initialize sine table with one cycle of a sine wave
for (int i = 0; i < 100; i++) begin
sineTable[i] = sin((2 * $f_pi * i) / 100) * 32767;
end
end
always @(posedge clk or posedge rst) begin
if (rst) begin
sineOut <= 0;
addr <= 0;
end else begin
sineOut <= sineTable[addr];
addr <= (addr == 99) ? 0 : (addr + 1);
end
end
endmodule
```
In this Verilog implementation, we use a lookup table to store the values of a sine wave. The sine wave is sampled at 100 points per cycle, and the values are stored in the `sineTable` array. The `addr` register is used to keep track of the current address in the table, and it is incremented on each clock cycle. The `sineOut` output is set to the value corresponding to the current address in the table, and it is updated on each clock cycle.
