- In stage 2 module definition add m_o
//> First stage of multiply
output[63:0] m_o;

// I don't get the Compute x / y part, but I do want to use x_o and  
y_o here in essence.
wire[31:0] m_o = x_o[15:0] * y_o[15:0];
wire[47:32] m_o = x_o[15:0] * y_o[31:16];
wire[63:48] m_o = x_o[31:16] * y_o[15:0];

- In stage 3 module definition add m
//> First stage of multiply result
input[47:0] m;

// Does a static shift work like this?
`QOP_MULT: res_o <= (m[63:48] + m[47:32]) << 16 + m[31:0];

That should do it on the math-side of things I hope. Still don't know  
whether this'll work in stage 2 due to the clock thingy.
