According to foreign media reports, it seems reasonable to see Hugo Paris, who just left Xiaomi, join the Facebook VR division because there has been a new personnel change in the VR industry in Silicon Valley. According to reports, Claude Zellweger, key leader of the HTC Vive design team and a key developer of HTC smartphone design language development, announced that he has joined the Google Daydream project. The party announced the news on Twitter and his HTC email address is no longer available.
In response, HTC officials responded: “HTC has confirmed that Claude Zellweger has left the company. We are very grateful for his contribution to HTC and I hope he can achieve good development in the future. HTC will continue to train and introduce talents. Make sure that the company's organizational structure has sustained strength and integrity.â€
Zellweger's departure does not seem to be good news for HTC. In 2014 it lost chief designer Scott Croyle. One year later, Croyle’s successor, Jonah Becker, also announced that he would leave to join Fitbit. Both were joined by HTC after their founding company One & Co was acquired by HTC in 2008. Their third partner was Claude Zellweger. Eight years later, the core figures of One & Co have completely left HTC.
However, Zellweger's departure will not affect HTC's mobile business, because he is mainly responsible for the HTC Vive virtual reality headgear.
Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
In addition to SCSI, IDE is also a very common interface. From the point of view of ease of use, IDE is more suitable for ordinary users. In addition, personal computer users not only need to configure a few peripherals, but also do not require high speed. Therefore, it is more appropriate to choose IDE interface. In addition, IDE also has the characteristics of high performance price ratio and wide application. Although the SCSI interface has many incomparable characteristics, the price of the interface and its peripherals is too expensive to be borne by ordinary users, which determines the limitation of its actual use range.
1. The working mode of IDE requires the whole process participation of CPU. When the CPU reads and writes data, it can't perform other operations. In this case, in the multitask operating system of Windows 95 / NT, the system reaction will be greatly slowed down. The SCSI interface controls the data reading and writing operation completely through the independent high-speed SCSI card, so the CPU does not have to waste time to wait, which obviously can improve the overall performance of the system. However, IDE interface has also made great improvements to improve this problem. DMA mode can be used instead of PIO mode to read and write data. DMA channel is responsible for data exchange, which greatly reduces the CPU consumption. However, comparing the CPU utilization of SCSI and IDE, we can find that SCSI still has considerable advantages.
2. The scalability of SCSI is larger than that of IDE. Generally, each ide system can have two IDE channels, with a total of four IDE devices. The SCSI interface can connect 7-15 devices, much more than IDE, and the cable connected is far longer than ide.
3. Although the price of SCSI device is higher, compared with IDE, the performance of SCSI is more stable, durable and reliable.
