The 128byte FIFO and the hardware support for CTS/RTS (that keeps the CPU from neededing to take action) are excellent efficiency enhancers. I just want the data to flow with as little CPU intervention as possible. Just set-up the buffer and go do something else. Cool.

It's funny -- we're so used to thinking in terms of megabytes and gigabytes (re a computer's main memory) that we forget how much difference a few bytes can make in something like a judiciously-placed FIFO

I guess another advantage of such IPs getting available for FPGA/SoC platforms would be to make life easier for tackling obsolescence of the original ICs. By making the clone of such popular but matured ICs based on programmable platforms, it helps in reducing the re-design efforts for extending the life of the product for much longer period and makes the development cycle shorter.

It also makes it easier to prototype in an FPGA before committing to an SoC

SoC, SoC FPGA, ASIC, ASSP- how my head hurts. I think you may need to do another blog on the alphabet soup we have created around our various Programmable Logic Devices...

Do you have a taxonomy you feel strongly enough to blog about? Maybe we need to put naming things back in the hands of engineers and take this mighty power away from the marketing types...

Actually, that would be a good one -- leave it with me :-)

I just have to remember to make sure I use my power only for the good :-)

LATEST ARCHIVED BROADCAST
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.
