Struggle, programmer -- Chapter 46 this situation can be recalled, but it was at a loss at that time

I am going to Shanghai Xinyuan on business today , Finally determine the specifications .

All roads of Zhangjiang hi tech are named after scientists , For example, zuchong road 、 Gauss path 、 Madame Curie road , This kind of atmosphere is really suitable for engineering men .

I stood in the hall of Xinyuan , Look at the posters on their walls , This is a map of Companies in Silicon Valley , Including Intel 、 Cisco 、 An industry giant like Oracle , Core original Verisilicon Impressively listed , This picture is here , It's still awesome .

Daiweimin, the founder of Xinyuan microelectronics, is a graphic chip technology CEO Daiweijin's brother ,Marvell Co founder daiweili is the younger sister of the first two , The three members of the Dai family are in the semiconductor industry Strength cannot be underestimated .

The person in charge and the engineer of the other side came out soon , Take us to the conference room .

The other five engineers lined up , At the top is the manager , We only have me and Peter Two person , I can't help straightening my chest , Want to cheer up .

As Party A for the first time , This role change really makes me unable to change .

In limine Peter It's the keynote speaker , After a brief exchange of greetings with manager Zhou of the other party , It generally describes the overall situation of the project , Shuang fan uses strange sentence patterns mixed with English to communicate , I don't understand many nouns .

I'm just a little attendant carrying bags , Just sit there and dress up .

Next, we start to get to the point , The other engineer began to ask questions about the details .

“ The signal PFDETECT Yes output to ISISR Of , instead of ISIER？“

“pfdetect Updated by chip ,pf bit come from control field Fourth place in the world , such as snrm Orders, etc .”

“IRBA0R/IRBA1R/IRBA2R What's the usage? ? Why is it set to 0x00800000 Of ring buffer Address ,register file There is no empty address in
    between .ring buffer Where is the space for ? How to use IRBA0R/IRBA1R/IRBA2R?”

“IRBA0R,IRBA1R,IRBA2R Should be buffer Entrance address , The specific value depends on the chip design , The chip is directly set to 0x800000 that will do .”

“P42,IRPLC2R/IRPLC3R in Preamble What does it mean , And IrDA Physical Layer Specification in PA Corresponding ？
    but SIR/MIR No, PA Of ？FIR Of PA Should also be 16, Why is this 0x0F?”

“premable Point to a few PA,sir Invalid ,mir Set to 2 individual ：0x7e,fir Set to 16 individual ：1000000010101000”

“ stay TXFCR At most 4 individual frame, Because of the present TXFL FIFO yes 4-step Of , But due to the 4-stepFIFO yes ring buffer Structure , So if Host CPU Yes TXFL FIFO Yes 5 All over , Will the last one overwrite the first one , If it can be covered , Which frame counts as the first frame transmitted ?”

“ Infrared remote control can only 1 frame , And it must be from the address 0x00000000 Start , Just write the data to buffer, Set the length , And irda Write irrpr Start dma Different , The infrared part passes through dmacr In register bit0 Set up 1 Start dma delivery . Switch bank All are cpu On going , Can't switch automatically .fifo If write 5 All over , The first setting will be overwritten . After data transmission ,dma Give an interrupt , But the physical layer is uninterrupted , That is to say cpu It is invalid for the physical layer to change the working mode after seeing the interruption ,cpu Only the currently set fifo”

Questions and answers like this last for hours , I am well prepared , Answer each other's engineers' questions one by one .

It's almost two o'clock in the afternoon after finishing all this , Wang, vice president of sales of Xinyuan, had dinner with us , He and Peter Exchange views on the industry in a cordial way .

Wang is always a handsome man , Every move has its bearing , This is a precipitation of experience , I thought. , When can you cultivate this kind of bearing .

When I get back , It's gone Peter Go alone , I have something else to do .

It is already plum rain season , It rained thinly , It's a little cold on my body .

Back to thebund again , There is a sense of right and wrong .

People in a hurry on the roadside , Those young people with strange green hairstyles shouted at me beyond,beyond.

Think of the past , And Xiaohui 、 Golden gun 、 Hiroko, they are together , Find the legendary thebund No. 6 among the piles of European buildings , Look inside , Look terrified ; I remember looking at the huge office building across the Huangpu River from the high-power binoculars , When I motioned Xiao Hui to see it, a strange woman passing by grabbed the telescope and looked like , It caused Xiaohui's frustration when he put his face up and got nothing . 

Lonely smile , The open arc of the corner of the mouth closes in fear because of the cold wind mixed with raindrops .

They are not in this city anymore , The original city has become so strange . 

by the way , And her , That is buried in my memory , People who don't want to touch again .

That one took my arm , Walking in the crowd , Always with a bright smile , A visitor .

Familiar streets , But I can no longer see the familiar people .

I want to go to the sentence in "half life" “ Man Zhen , We can't go back .”

...... 

Chen Xi said before , Like to eat sushi .

Sushi in Shanghai landmark is good , Before returning to Wuxi, I went to buy some pieces .

“ my beloved wife , I brought you some delicious food .” I sent her a text message in the car .

“ Your majesty really lives high in the temple and never forgets his people ？”

I laughed .

“ I am far away from the Jianghu and never forget the beauty .”

It was very late to return to Wuxi that day , When Chen Xi took sushi from my cell phone , Put it in your mouth to show a satisfied smile , I also smiled happily .

Always on a rainy day
Escape from a certain past
But the raindrops just make it happen
The song from the bottom of my heart repeatedly prompts in the cerebral cortex , Yes , It's time to wave goodbye to the past , In the best season , Let me meet you .

I turned my head , Look at Chen Xi's eyes full of stars .

original , Happiness is so simple .
