基于FPGA的红外焦平面驱动和采集逻辑设计

利用ALTERA公司生产的CyconeIV FPGA实现了非致冷型红外焦 平面的时序驱动以及视频采集和温度采集的逻辑设计。将设计好的逻辑模块封装成了两个外设 控制器，并将其作为Nios II处理器的外设而挂接在了Avalon总线上。本逻辑设计已经应用在实际 产品当中，并具有占用逻辑资源少、功耗低、时序稳定可靠以及针对不同焦平面而易于移植 等优点。

Logic Design of Infrared Focal Plane Driver and Acquisition Based on FPGA

The logic design of timing driving, video acquisition and temperature acquisition is realized for an uncooled infrared focal plane by using a CyconeIV FPGA from Altera Corporation. The logic module is packaged into two peripheral controllers which are connected to the Avalon bus as the peripherals of a Nios II processor. This logic design has been used in actual products. It has the advantages of less logical resource, lower power consumption, stable time sequence and easy portability for different focal planes.
