Serialized PCI: The Next Bus Link News & Analysis 6/21/2000 Post a comment We are running out of DSP board bandwidth. We need more as DSPs take on more tasks and we pack more DSP power into boards and modules. One solution is a faster system bus. But Ray Weiss believes a new alternate bus is also emergingserialized PCI.
PCI-X Moves Out News & Analysis 6/9/2000 Post a comment It looks like the PCI-X, the new PCI extension, will become a real standard for embedded systems as well as one for PC servers. And PCI-X is needed; it cleans up PCI and opens up PCI's bandwidth potential, especially for burst transactions. Additionally, PCI-X solves the limiting "PCI Read Problem," enabling PCI Reads to achieve PCVI Write efficiencies.
PCI-X Exposed News & Analysis 6/9/2000 Post a comment PCI-X delivers a better, faster, safer PCI. It is more complicated, particularly for bridges, but is worth it for a significant upgrade in bandwidth and operating efficiency.
Drop Multidrop and Switch to Switched-Fabric Design How-To 6/8/2000 Post a comment After years of reliable service, the traditional multi-drop architecture of microprocessor-based systems is reaching its limits. Hanging peripherals off of a long, wide signal bus won't give designers the system data bandwidths they need for tomorrow's designs. Site director Rich Quinnell suggests that designers look carefully at the emerging switched-fabric architectures and plan for the software changes that must follow.
DSP + PCI-X = Processing Bandwidth News & Analysis 6/8/2000 Post a comment The time has come. DSP board and system vendors have a decision to make: to move to the PCI-X bus or not. PCI-X, the extension of the venerable PCI bus, will happen. The infrastructure is falling in place to support PCI-X and the system makers are on their way to incorporating PCI-X into their servers. For them, PCI-X offers higher and more stable bandwidth, overcoming some of the key weaknesses of the original PCI bus.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
