Re: Already waiting for the automotive instrument cluster to boot

I have no keyboard with which to see what software the autombile dashboard is loading. On my computer, CTL-ALT-DEL doesn't display loaded programs but the Task Manager does. While there may be no unexpected programs in the "Applications Tab", the "Processes" tab reflects a tremendous number of threads (most of which are system processes that I don't have control over) which seem to multiply even when all the applications are shut down. Periodic reboots seem to be necessary to flush them out and free up processor resources.

Before you do anything on your just booted up computer,  do a control+alternate+delete instruction and see how many programs have booted up. As long as you and Microsoft have instructed all there programs to startup ...

The problem with the boot-up time for the Car instrument cluster?

I think the solution lies in not booting up the cluster panel after the ignition key is turned on , but keep it in sleep mode while the engine is not running so that it can wake up instantly as sson as the ignition key is detected.

This should be possible with the very low power drwn by the MCU from the Car battery isnt it?

Damn, it is already a reality! 

Actually, Ino's question about booting an automotive cluster quickly is indeed one example taht convinced me there must be a real pressing market need for this -- not five years from now, but today.

Already waiting for the automotive instrument cluster to boot

The last car that I rented on a business trip had an instrument cluster that booted like a computer complete with a musical chime, a startup screen, and finally the data of interest. It also had a shutdown sequence complete with graphics and another musical chime.

Ino's question: "What if you turned on the ignition of a new car, and your instrument clusters don't show up instantaneously?" is a reality and it isn't nice. My laptop computer takes 5 minutes to boot up.  How long will car instrument clusters take to boot up before consumers complain?

@boblespam, good, on the ground observation. Much appreciate your sharing the info!

So, what you are saying is that even though the improved performance for hyperflash, it's not worth switching from RAM to hyberflash. Correct?

In my opinion, it is the variety of applications that Spanision is offering which will distinguish these solutions if anything....automotive is great but when you can get into other things as well, that's where the real oppotunity lies.

I just finished designing a big (high end) digital cluster with a Fujitsu SoC, 128MB of parallel NOR for the OS and main app and a big NAND flash for data. XIP in this context is still too slow (I have very fast RAM).

Boot time is a real big issue for this application, it's good that Spansion (and Fujitsu) found a solution that looks efficient in term of performance and price.

On a smaller project based on a Renesas chip we use quad SPI with a nice thoughput, I think it will remains the main opponent of hyperbus: it's cheap and will get faster with time.

XIP will save a little bit of RAM, it's also good to have, but I think it will still be too expensive for the smartphone market.

@Junko: considering that NAND using leading edge processes, while This uses 62nm which is quite old for flash, and the small size of those chips , i would say this doesn't pose a threat to NAND in smartphones.

My question for EE Times community is this:

Spansion's new HyberBus I/F is said to allow faster boot time, direct execution in place from flash. Can it buck the trend of NOR market erosion by smartphones?

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
