今天去拍戶外的照片, 富田農場, @@整個場子都是新人, 一車進去要500 , 可以換四杯飲料,
拍的普通, 大家都差不多.

晚上的課, 跟之前差不多, 都是介紹 SOC design 的流程跟tool , 相當於週三(Verification) + 週四(Soc Design)的簡介, 不過真的是簡 介...

還沒到期中, 就開始懶散了 ~~

Recursion 的問題:

• unbound argument.


• stack maintain difficult.

Task vs Function

• Tasks can't return value


• Function can return value.


• task do_this( input int data=0, addr=0, ctrl=2 ), default arguments :


• for example: do_this(5,2 ) 、do_this( ,,0), do_this( .data(5), .addr(2) );


• const ref let argument Readonly.

雜項:

1. automaic 函式結束記憶體隨即釋放, 節省記憶體使用.


2. void 表不回傳值, 省空間only.


3. static 用法同C.


4. ref ( call by reference ) 有點不相同, 不過更簡單, **問題已經幫你處理好了.

今天選舉
國民黨的馬蕭配共獲得765萬8724票，民主進步黨的謝長廷、蘇貞昌則獲得544萬5239票，得票率41.55%，藍贏綠221萬3485票。

雖然很爽....但感覺跟我沒太大的直接關系 -.- 功課還是要做, 班還是要上, 學費還是要繳...沒甚麼不同, 也沒一樣能打折, 薪水有加? Paper少一半??? 並沒有.....不要太投入的好.

功課都沒做 @@ ...積壓了好多作業呀..天呀...先看完這次的Paper吧.
這學期壓力太大了...比上學期更大了, 一星期六堂每天上之外, 每篇Paper都英文, 又有好幾個Lab在做. 想研究的東西還沒空弄, 先擱著.

今天上的還是跟計組一樣, 只是延續上一次的課. 講解了IPHONE 的構造.


題外話:
1.目前碩專學長 H264的Project 被 Cancel , 取而代之是研究 ..gphone, Android and porting to Arm and verification.

2.影像如果未做前置處理, 而要後處理的話幾乎是無解. 老師給的建議還是朝向前處理.
原先的問題是:
前提:兩個Encoder( EnA , EnB ) , 以每秒 30張, CIF, 同時對一個Video Record.錄個幾秒, 然後作Decode把每一張都變成YUV or RGB.

1. 把 EnA 第10張 跟 EnB第10張做比較 (結果應該是要一樣)
2. 把 EnA 第10張 跟 EnB第11張做比較 (結果應該是要不一樣)

但實際上, 做模糊的判斷, 有可能造成 1. 是不一樣, 2.是一樣的結果.
這個問題下星期來去找專門做影像的張老師問問.

3.

• TW WiMax 即將要開發了, 有可能起來, 也有可能受到 ISP擠壓.
• Gphone 起來, 不過針對每種Hardware的調校也是個挑戰, 加上Micro xxx 這面牆. Windows 上的資料要跟Handset上資料能做同步關系, 要看看 Android能提供出甚麼了, Office 系列就不用說了是基本的, 至少要有類似 Outlook 功能的同步.

這兩件事看起來完全是無關的事, 但我覺的有很大的關係, 如果說WiMax真讓台灣做起來了, 費用能推的出去, 這就是大事了. 以前HSDPA出來之前, 台灣並沒有高速的無線網路, WIFI就不用說了, 走個幾步路就要換台了, 那不算是能移動的無線網路, 而開放的手持式裝置 + 高速無線網路....目前尚無Killer application. 就要看這兩個規格能不能衝出封鎖線了.

今天課講的少, 但一上課就一個精彩的, Stenly被叫上去講課, 根據上星期所研究的SWI address從LR register 取出後作 24bit mask , 整個ADS code 流程做講解, stenly 提供了一份報告. 被老師引用進課程, 幹的不錯, 唯一的缺點, 用Open office , 格式爛掉..... ARM_SWI分析..至於檔案嘛, 自己去跟stenly要.

今天講解 Lab1 , CodeWarrior 的使用, 助教示範了一下, 還示範了command line的使用....用過了GUI誰還用command line -.-. 用cmd line debug , 跟用 gdb一樣....光debug就暈倒了..
ADS下的參數跟gcc類似, 只是名稱不同.

ADS Problem: default-1-2-0-0.ses FIX:

• Options->configure interface-> ATTACH；configure target-> ARMUL
• Project/Remove Object Code; recompile.

Lab1:

P1-26:ARMASM doesn't include ARM-to-Thumb header automaticaly as ARMCC does. You must manually change the state to thumb at initial.

Part I: Interface methods( Task/function ) (wrapper ).

• Modports:
• import / export ( import: Interface本身提供Function. export:由外部提供), 想當然爾, export不可合成. import 有條件(如果未用及本身未提供的東西即可).

Ref: System Verilog For Design Page 308.

PartII: Operators

The same as C Language. If got race condition , it synthable but flipflop.

for example: a = a + 1 become a<=a+1;

PartIII: Flow control Instructions:

• fork join( join_any, join_wait, join_all ), disable fork
• for
• while
• case

if control veriable( counter ) not static , it's not synthable!

for example: do{ .... } while( counter <>

remember full case in case block!!

爸爸真偉大

雖然老爸不在了, 我也還沒成家, 但隨著年紀的增長, 漸漸的能體會到爸爸的壓力.
紅白帖的到來、家庭食衣住行的開銷、房貸的壓力、保險的支出、三不五時要滿足家人的願望、更有小孩的一堆balabal.....

一個爸爸像是萬能的機器人, 必須要扛下所有的事, 像是

上天賜與我神奇力量....引用自神力女超人.

.

隨著寥寥無幾的存款, 每個月的透支, 伴隨著需要思考下個月的房貸怎辦、這個時後要是失業怎麼維持, ....壓力真的是會讓人白髮. 再來一次~~

.

爸爸真偉大

.

以前的爸爸只要學的一技之長, 可以維著家庭的運作.

現在的爸爸, 只有一技之長只能餵飽自己, 要花更多的時間去學習更多的東西.

• 為了爭一口飯吃每個月要有買菜錢.
• 為了能有個家, 要買房子付貸款.
• 為了保障自己掛了家庭不致於亂了步調, 要有五百萬的保障.
• 為了要能看第四臺, 洗熱水澡, 要繳水、電、瓦斯費.
• 為了能上網打電動, 要繳ADSL上網費..... 我看這是唯一的娛樂了 -.-.

被這種現實的壓力包覆著, 生活幾近沒有自己的空間跟時間, 更別談甚麼品質了.

爸爸也是人呀~.

難道這就是傳說中 : 爸爸的宿命~~

講解Thumb 指令類別, 及該模式下, 如何以16bit 來操做 32bit 的位置.
兩個issue:

• BL 如何達成 22bit address.
• SWI Arg 有何意義.

1. BL 經Stenly 查尋 ADS sample code , BL利用compiler 實作兩次, 以HI, Low bit 控制該次填入Address.
2. SWI Arg目前推估是用於Software Interrupt 對映, 而非單純的註解, 不然對於Software Interrupt 只能一種無法合理解釋.
3. Thumb2 performance 表示 performance 跟ARM 一樣, Size 跟Thumb一樣.(Page 95).
4. 下次講 ARM/Thumb interworking(重要) w/ 3 Stage Pipeline.

今天上有關 system verilog instruction, operat, 跟C沒甚麼兩樣, 有在寫應該就都懂.
老師把一些語言定義:

• System Verilog - for verification.
• System C = for Modeling.
• Verilog = for design.

還有提到一些 "Bluespec" <-- 應該是這樣念, 目前沒學到.

其中 struct , union 常用於Interface (使用Packet type).

packet type : reg, bit, byte 這類.

unpacket type : int , integer 這類.

PS1:老師說Subby 適合跑 verification, 我適合寫Modeling.

本週大綱

1.The Register Banking ! Important !

• There are 7 mode in ARM.
• Data Processing Instruction
• 37 register( CPSR、5SPSR、31GPS ) and PC.

2.CPSR status(NZCVQ ________IFT+MODE).

3.It's different of MIPS and ARM.

• Condition code of every command. ( compiler will get best solution not only branches but all ARM instructions).
• I have try to compile some ARM code by gcc 3.4 of xscal(arm9) , but i didn't see any like "ADDEQ" command.
• Try the command :>armeb-linux-gcc -S t.c -o t.s

for example:

int main(){

int i = 0;

i= ( i ) ? 0 : i * 5;

}

醫工系的東西感覺上跟資工電子沒甚麼兩樣，不是想像中對醫療電子有深入研究，
沒有對醫用Sensor 做研究，血壓、體溫、心跳這類東西出現N年了，目前看到的還是這些東西。

沒有新意

撇開高價的醫療器材不談，一般User 買的起的醫療用品，水銀溫度計變成數位溫度計，水銀血壓計變成數位，這些東西對User來說有差嗎？？血糖計勉勉強強還說的過去，算是近年來開始普及大眾的東西。

學習目標

還是要朝向生科系學習，要做出能造福一般民眾的醫療器材，首先要了解身體構造，從學習、實驗找idel才有機會。

what is the commerce value chain

Homework 3-01-2008
Q1. According to the book by Treese and Stewart, what is the commerce value chain? Why not see them on an individual basis?

A1: The components of general commerce value chain are as follows

• Attract customers: Marketing - get and keep customer interest.
• Interact with customers: Sales - turn interest into orders( generally content ).
• Act on customer instructions: Order management - order capture, payment, fullfillment.
• React to customer requests: Customer service, technical support.

But I don't think so , Although most individuals are unable to load, but many in Yahoo, ebay auction of the individual, Also to the above-mentioned four parts in the Internet.

For example:小婷電腦，she has four parts similar to the above, Weekly email latest weekly goods, orders to meet customer needs.

Q2. Is the Internet different from other media? Why?

A2:

• Time: No time difference restrictions on the Internet 24 hours of service.
• Space: No geographical restrictions, even thousands of kilometres apart, can be a very short time to spread the message throughout.
• Free: All information not spend a dime of money readily available.
• Exchange: All information can be exchange more transparent.

For Example:

• More and more people, do not read the newspaper in Taiwan, They don't have so much time to read itand they read the news in the Internet like Yahoo, Msn News. The higher cost of human society, newspapers from the Internet was replaced by the more serious cases.
• Many people looking for job not looking at newspaper, but to http://www.104.com.tw/.

Q3.Convert one of your Word document using Google docs.

A3:

• This is the HELLO_WORLD sample at Google docs.
• You can view the Hellow_world.c here in my blog.If you do any change in hello_world.c , just press Publish->Republish post then you will see the new Hellow_world.c in blog.

Q4. Customize your blogs.
A4:I already done it before!
