第一版YL2410開發(fā)板的BIOS 功能比較簡單,上電之后,LCD顯示藍(lán)色、綠色、紅色三個豎條 同時串口顯示如下: Power on RESET ************************************ * * * YL2410 Board BIOS V2006 * * Http://www.ucdragon.com * * * ************************************ NAND Flash Boot Please select function : 0 : USB download file(通過USB下載文件) 1 : Uart download file(通過串口下載文件) 2 : Write Nand flash with download file(將下載的文件燒寫到NandFlash) 3 : Load Pragram from Nand flash and run(從NandFlash裝載文件并運行) 4 : Erase Nand flash regions(擦除NandFlash區(qū)域) 5 : Write NOR flash with download file(將下載的文件燒寫到NorFlash) 6 : Set boot params(設(shè)置Linux啟動相關(guān)參數(shù)) 7 : Set AutoBoot parameter,1:linux 2:wince(設(shè)置WINCE自啟動)

用verilog設(shè)計密勒解碼器 一、題目: 設(shè)計一個密勒解碼器電路 二、輸入信號: 1. DIN:輸入數(shù)據(jù) 2. CLK:頻率為2MHz的方波,占空比為50% 3. RESET:復(fù)位信號,低有效 三、輸入信號說明: 輸入數(shù)據(jù)為串行改進(jìn)密勒碼,每個碼元持續(xù)時間為8μs,即16個CLK時鐘;數(shù)據(jù)流是由A、B、C三種信號組成; A:前8個時鐘保持“1”,接著5個時鐘變?yōu)椤?”,最后3個時鐘為“1”。 B:在整個碼元持續(xù)時間內(nèi)都沒有出現(xiàn)“0”,即連續(xù)16個時鐘保持“1”。 C:前5個時鐘保持“0”,后面11個時鐘保持“1”。 改進(jìn)密勒碼編碼規(guī)則如下: 如果碼元為邏輯“1”,用A信號表示。 如果碼元為邏輯“0”,用B信號表示,但以下兩種特例除外:如果出現(xiàn)兩個以上連“0”,則從第二個“0”起用C信號表示;如果在“通信起始位”之后第一位就是“0”,則用C信號表示,以下類推; “通信起始位”,用C信號表示; “通信結(jié)束位”,用“0”及緊隨其后的B信號表示。 “無數(shù)據(jù)”,用連續(xù)的B信號表示。

This a simple bootloader for AT91SAM7{S,X}{64,128,256} processors. It permits you to download new code to the device over USB. This bootrom is installed at address 0x00000000 in the ARM, which means that it is the first piece of code to execute after RESET. At startup, it waits for a few seconds to see if the downloader is trying to connect. If not, then the bootloader gives up control and jumps to your program. If the downloader is trying to connect, then the bootloader receives the new program over USB and writes it into flash.

this a pack include source code for quartus 2. It is an implementation of the LC2. The LC-2 computer is described in Introduction to Computing Systems from Bits & Gates to C & Beyond by Yale Patt and Sanjay Patel, McGraw Hill, 2001. The LC2 model can be run as a simulation or downloaded to the UP3 in a larger model, TOP_LC2 that adds video output. Push buttons RESET and single step the processor and a video output display of registers is generated. This state machine VHDL-based model of the LC-2 includes all source files. Currently compiled for a Cyclone EP1C6Q240 FPGA.

ARMask.The ARM has six operating modes: • User (unprivileged mode under which most tasks run) • FIQ (entered when a high priority (fast) interrupt is raised) • IRQ (entered when a low priority (normal) interrupt is raised) • Supervisor (entered on RESET and when a Software Interrupt instruction is executed) • Abort (used to handle memory access violations) • Undef (used to handle undefined instructions) * ARM Architecture Version 4 adds a seventh mode: • System (privileged mode using the same registers as user mode)
