Embedded - FPGAs (Field Programmable Gate Array)

Field Programmable Gate Arrays (FPGAs) are integrated circuits that are designed to be re-programmed for custom logic applications. EP2AGX260EF29C4N is a leading FPGA chip from Altera Corporation, specialized for low-power, high-performance designs.

FPGAs are commonly used for digital signal processing (DSP) applications, including industrial, communications, multimedia, and consumer electronics applications. The EP2AGX260EF29C4N, in particular, is designed for re-programmable logic, combining the advantages of high-speed logic and wiring for maximum system integration capabilities. It also features numerous memory elements, such as RAM and ROM, for a more efficient design.

The EP2AGX260EF29C4N device is structured into two parts: the reconfigurable logic elements and the configurable I/O cells. The logic elements, or clusters, are composed of four LEs. Each LE contains two dedicated Look-Up Tables, which are used as memory elements and programming blocks for complex logic functions, as well as four dedicated 18-bit arithmetic logic functions. The Look-Up Tables can store up to 40 four-bit words, while the four arithmetic logic functions provide the ability to perform a variety of math computations such as add, subtract, multiply, divide, rotate, and logical comparison operations.

The configurable I/O cells are used to interface with the external environment and connect to other devices in the system. Two configuration cells and one status cell configure the overall behavior of the I/O cells. This includes the pull-up, pull-down, output enable, hysteric-set, and direction control settings. These settings allow the EP2AGX260EF29C4N device to be used for a variety of designs, including wireless and industrial applications.

Overall, the EP2AGX260EF29C4N device is a high-performance FPGA with many features that make it an excellent choice for demanding applications. It is an ideal solution for digital signal processing, providing the necessary speed and versatility for complex logic operations. It has been designed for low-power operations, allowing for efficient design and long term stability.
