Abstract

When designing the MC68020, we wanted to use a branch PLA in the microsequencing schema similar to that used on the MC68000110. However the circuit constraints placed on MC68020 were much more severe. The MC68020 was designed to have twice the operating frequency and the die is four times as large (much longer RC delays associated with some signals).
