4.1 IP core definition and basis

IP (Intellectual Property) core, the intellectual property core, is the basis of the reusable design methodology of integrated circuits. As a reusable module, IP cores have usually passed design verification. The designer designs on the basis of the IP core, which can shorten the period required for the design. The IP core can be provided by one party to another party through an agreement, or can be owned by one party alone. The concept of IP core stems from the patent certificate of product design and the copyright of source code. Designers can use the IP core as the basis for logic design of application specific integrated circuits or field programmable logic gate arrays to reduce design cycles
