Week 2 – Combinational Logic

Lecture

• N-bit adder + testbench

• Mux, ALU

• Encoder

• Decoder

• Verilog functions

• LUT

Assignment

• Create module to apply quantization and ReLU: y = relu(quant(x))

  • Quantization: q = y/(2^f), where f is a constant

  • ReLU z = (y > 0) ? y : 0

• For each combinational element in [mux, encoder, decoder, relu]

  • Consider input of 3 bits

  • Decompose into sum of products

  • Decompose into product of sums
