Backplane tutorial: RapidIO, PCIe and Ethernet
RapidIO, PCIe, and Ethernet each offer unique benefits. We explain how each technology works, and examine its strengths and weaknesses. We also show why RapidIO is often the best choice for embedded systems.
PCI Express bridging options enable FPGA-based configurable computing
In many embedded systems, FPGAs have augmented or displaced dedicated MPUs and DSPs, so endpoint bridging solutions for PCIe must enable FPGAs to fulfill their new role.
A primer on extending serial ports in embedded designs
Vikas Shukla provides some reminders about the many ways that an embedded systems developer can add more serial ports to a design if they are needed.
Evolving passive optical networks (PONs) demand FPGA design flexibility
Standards uncertainties abound going forward with PONs; the bedrock for bridging those issues is scalability and flexibility, both of which are provided by FPGAs.
Comparing IP integration approaches for FPGA implementation
Avoiding the fixed routing and timetable of a standard bus can open up new avenues for design and restore a bit of glamour and creativity to an otherwise mundane project.
Back to the future: Low-cost, low-bit-rate serial communications with Manchester Encoding - Part 2
As a follow up to Part 1 on the basics of Manchester Encoding, Robert Guastella provides a realistic example of how to implement the protocol in a real world low bit rate serial wired or wireless design using a PIC MCU.
Back to the future: Manchester encoding
When commercial options fail, try using Manchester encoding and other time-tested protocols in low-cost, low bit-rate serial communications.
Introducing MagnaPHY high-speed chip-to-chip serial interconnect
Everything you need in your chip-to-chip interconnect (high-speed, low pin-count, etc.); sort of like PCIe but without the overhead and oriented toward high-speed embedded applications.
