1. What is FPGA Field Programmable Gate Array?
FPGA (Field Programmable Gate Array) is a semiconductor device that allows users to change and configure the internal connection structure and logic units of the device through software means after manufacturing to complete the digital integrated circuit of the established design function. FPGA consists of programmable logic resources, programmable interconnection resources and programmable input and output resources, and is mainly used to implement sequential logic circuits with state machines as the main feature.
FPGA is a product further developed on the basis of programmable devices such as [PAL (Programmable Array Logic) and GAL (General Array Logic). As a semi-custom circuit in the field of application-specific integrated circuits (ASIC), it not only solves the shortcomings of customized circuits, but also overcomes the shortcomings of the limited number of gate circuits of the original programmable devices. FPGA realizes a unique method of digital circuits by providing programmable hardware blocks and interconnections that can be configured to perform various tasks, making hardware development more flexible. -
