嵌入式系統(SOC)算是近幾年來相當熱門的話題
許多人也紛紛朝這方向研究及分析
不過也有大多數的人不得其門而入
在此小弟簡單的介紹一下
要使用SOC之前 我們必須先考量一個問題
我們所建立的SOC功能為何 目的為何
如果說只是單純建立幾個基本正反器
或者是幾個簡單的邏輯閘組成的電路
小弟是認為這用硬體描述語言就可以解決
甚至於買塊麵包板跟IC回來插一插就搞定了
若說用到SOC 有點殺雞焉用牛刀之感
所以確定自己的需求 是相當重要之事

淺談嵌入式系統(SOC)

DE2-70 的燒錄模式
燒錄模式:
1. JTAG Mode: The FPGA will retain this configuration as long as power is applied to the board; the configuration is lost when the power is turned off.
2. AS Mode: When the board's power is turned on, the configuration data in the EPCS16 device is automatically loaded into the Cyclone II FPGA.
檔案類型:
1. JTAG Mode: The FPGA can now be programmed by using the Quartus II Programmer module to select a configuration bit stream file with the .sof filename extension.
2. AS Mode: The EPCS16 chip can now be programmed by using the Quartus II Programmer module to select a configuration bit stream file with the .pof filename extension.
