In the last article, i wrote about the physical layer, now let’s take a look in the next layer the data link layer.
The Data Link Layer serves as the “gatekeeper” for each individual link within a PCI Express system. It ensures that the data being sent back and forth across the link is correct and received in the same order it
This is another post that was requested by a user, and as always i’ll do my best to put in a few articles the basic information that you’ll need to understand how it works at depth level.
PCI Express (or PCIe) is a high-speed serial computer expansion bus designed to replace the older PCI, PCI-X and AGP standards.
The first… Read More
Synopsys just announced the availability of their IP solution supporting CXL (Compute Express Link). This new protocol is going to be an important component for several applications expected to be shipping starting in 2021. CXL is an alternate protocol that runs on the same physical layer as PCI Express (PCIe). Among other usages,… Read More
IPnest has released the 9[SUP]th[/SUP] version of the Interface IP Survey, ranking by protocol the IP vendors addressing the Interface segments: USB, PCI Express, (LP)DDRn, MIPI, Ethernet & SerDes, HDMI/DP and SATA. When the 1[SUP]st[/SUP] version has been issued in 2009, the IP segment was weighting $225 million and the… Read More
If your company develops Design IP to support well-known protocols like USB, PCIe, HDMI, DDRn memory controller, MIPI specification (and more), it’s crucial to know your competition, the market size by segment, and even more important the market potential by segment. The latest can be obtained by the Compound Annual Growth Rate… Read More
It goes without saying that VIPs really play a Very Important Part in SoC verification today. It has created a significant semiconductor market segment in the fabless world of SoC and IP design & verification. In order to meet the aggressive time-to-market for IPs and SoCs, it’s imperative that readymade VIPs which are proven… Read More
Semiconductor IP is a relatively established frontier for innovation in Silicon Valley but it is not as easy as it looks. It certainly is not as easy as the two year old start-up Mobiveil has made it look. With a team of more than 100, led by experienced Semiconductor IP professionals, Mobiveil already has a portfolio of silicon proven… Read More
Non Volatile Memory (NVM) is a superb technology, at least if you appreciate the physical law behind: storing a data in an embedded location with no physical link, as you charge a cell by influence and read it without physically accessing the stored data. Although the semiconductor industry is building NVM IC for about 30 years now,… Read More
How to best forecast a specific protocol adoption? One option is to look at the various IP sales, it will give you a good idea of the number of SoC or IC offering this feature on the market in the next 12 months. Once again, if you wait for the IP sale to have reached a maximum, it will be too late, so you have to monitor the IP sales dynamic when… Read More
We have already discussed the recently released M-PCIe ECN from PCI-SIG in Semiwiki at the end of 2012, but the new “standard” (in fact an Engineering Change from PCI-SIG and MIPI Alliance) was only real on paper, at that time. The upcoming webinar from Synopsys, M-PCIe: Utilizing Low-Power PCI Express in Mobile Designs, shows … Read More
