Digital signal processors (DSPs) are specialized microprocessors designed specifically for digital signal processing, usually in real-time. DSPs can also be used to perform general-purpose computations, but are not optimized for this function.
Field-programmable gate arrays (FPGAs) have a different architecture than SPLDs and CPLDs, and typically offer higher capacities. FPGAs are also known as logic cell arrays (LCA) and programmable ASIC (pASIC).
Programmable logic devices (PLD) are designed with configurable logic and flip-flops linked together with programmable interconnect. PLDs provide specific functions, including device-to-device interfacing, data communication, signal processing, data display, timing and control operations, and almost every other function a system must perform.
RF and wireless chips are integrated circuits (IC) that are designed specifically for radio frequency (RF), microwave, and other wireless communications or data transmission applications.
Serializer/de-serializer (SERDES) macro-cell circuits receive fast serial signals (on the order of Mbits/s or higher) and de-serialize them into slower parallel signals. Some SERDES circuits can be programmed like any other PLD.
Specialty communications and wireless chips are specialty or proprietary products and accessories related to communications, wireless and telecommunications chip products.
