4. Programmable logic networks

Programmable logic arrays are circuits that provide the user with basic combinatorial and sequential logic elements of a certain granularity, whose connections he "programs" himself. This involves programming the interconnections of basic hardware elements, not to be confused with software programming (writing a program) of a processor. The ability to program interconnections means lower performance than "full custom" ASICs for an application, both in terms of clock frequency and integration density. For a much lower cost, they provide the user with sufficient performance for a very wide range of applications, depending on the different types of programmable logic circuits available. What's more, once an application has been developed and is running on a programmable logic array, if the number of circuits required justifies it, it can be easily migrated to an ASIC-type circuit by wiring...
