Hardwire Logic instead of MicroprogrammingHeritage/1 decodes instructions using logic circuits, that is actual gates. This avoids the speed contraint imposed by microcode storage if Microprogramming were otherwise employed.
Decoding by pure logic is interesting since the design is made based on Boolean algebra rather than "intangible logic", allowing the designer to think as an electrical engineer instead of a programmer. It also matches the Heritage/1 design philosophy in the sense that "Software is external to the Machine" and as such it has to be loaded on a hardware that has full-started already.
In section Building sequences with combinatorial logic this techique is explained in general terms.
