Altera Corporation is a global semiconductor company. The Company designs, manufactures, and markets high-density programmable logic devices (PLDs), HardCopy ASIC devices, pre-defined design building blocks known as intellectual property (IP) cores, and associated development tools. Its PLDs, which consist of field-programmable gate arrays (FPGAs), and complex programmable logic devices (CPLDs), are semiconductor integrated circuits that are manufactured as standard chips that its customers program to perform desired logic functions within their electronic systems. With its HardCopy devices the Company offers its customers a migration path from a PLD to a non-programmable implementation of their designs. Its customers can license IP cores from the Company for implementation of standard functions in their PLD designs. In April 2013, the Company acquired TPACK, a wholly owned subsidiary of Applied Micro Circuits Corp.
