PLA versus bit slice: comparison for a 32 bit ALU
Ewald Soutschek, M. Pomper, Karlheinrich Horninger · IEEE Journal of Solid-State Circuits · 1982
The PLA technique and the slice technique have been chosen to build a 32 bit wide ALU. Both techniques have a high degree of regularity and are used to soften the design time of complex logic circuits. In a given technology, the PLA is approximately twice as fast as the bit-slice solution (22-35 ns), but also needs more area (4.2-1 mm/SUP 2/).
