[SOLVED] pls give me idea about LUT verilog

[diaz080]

i have no idea about this LUT..need 2 design a 3 bit multiplier using this method..any help

A multiplier using a Look Up Table with 3-bit inputs?

Use the two inputs as an address to a memory and the data at each address is the multiplied value of the two inputs.

You have a 6-bit input LUT. Lower 3 bits are multiplier; high 3 bits are multiplicand. Data at address 0 is 0 (0 x 0). Data at address 10(001010) is 2 (001 x 010). Data at address 27 (011011) is 9 (011 x 011) etc.
