Logic analyzers, though originally intended for debugging parallel logic, remain important in the development of ultra-high-speed serial-bus hardware, even though the data rate of such buses often ...

Standard parallel-bus structures are reaching their performance limits. The only way to increase system bandwidth is to switch to a serial-bus structure. Although serial structures promise enhanced ...

After a youth spent playing with Amigas and getting into all sorts of trouble on the school computer network, I’ve always had a soft spot in my heart for hardware from the 80s and 90s. This extends ...

A shared channel that transmits data one bit after the other over a single wire or fiber; for example, Ethernet uses a serial bus architecture. The I/O bus from the CPU to the peripherals is a ...

PCI Express (PCIe) has been around since 2003, and in that time it has managed to become the primary data interconnect for not only expansion cards, but also high-speed external devices. What also ...

This is just a general question. I know, obviously, that there are RS-232 "serial ports" and IEEE 1284/Centronix ports "parallel ports," and that these are "digital" connections. Then you have things ...

Increasing numbers of motherboards carry PCI Express slots. James Morris explains why this new serial bus standard is replacing the older PCI parallel bus and how the move benefits video editors When ...

Today, links such as PCI Express, HDMI, and USB are ubiquitous. But it wasn’t that way 20 years ago. The last 20 years have seen an explosion in the number of serial-link applications. This article ...

If you've been using computers for more than a couple of decades, you've probably used a serial port to attach peripherals like your mouse and modem. Until the USB standard rendered them obsolete in ...

This article is part of Now and Then series and part of Electronic Design's 70th Anniversary series. Processors and memory have changed radically over the past 70 years, but the variability of those ...
