Rakendustesisesed, also known as application-specific integrated circuits (ASICs), are integrated circuits (ICs) customized for a particular use, rather than intended for general-purpose use. They are designed to perform a specific function or set of functions, often with high efficiency and performance. ASICs are created using the customer's design specifications and are fabricated in semiconductor facilities.

The design process for ASICs involves several stages, including system definition, functional specification, architecture definition, circuit design, layout design, and testing. The design is typically created using hardware description languages (HDLs) such as VHDL or Verilog. Once the design is complete, it is sent to a semiconductor foundry for fabrication.

ASICs are used in a wide range of applications, including telecommunications, automotive, aerospace, and consumer electronics. They are valued for their ability to perform complex tasks quickly and efficiently, often with lower power consumption than general-purpose processors. However, the high cost and long development time associated with ASICs can be a significant barrier to their use.

There are several types of ASICs, including full-custom ASICs, semi-custom ASICs, and programmable logic devices (PLDs). Full-custom ASICs offer the highest performance and efficiency but are also the most expensive and time-consuming to develop. Semi-custom ASICs, on the other hand, offer a balance between cost and performance, while PLDs provide flexibility and reconfigurability at the cost of lower performance.
