How Optical Switches Can Cut AI Hyperscale Data Center Power by 40%

I’m about to wax eloquent on a new generation of optical switches that are poised to revolutionize the communication capacity and performance of data centers—especially the AI and hyperscale flavors (ooh, tasty—and very real, as operators like Google have already proven)—while also cutting power by 40%, but first…

The phrase “It’s a funny old world, and no mistake” is an informal, colloquial British … Read More → "How Optical Switches Can Cut AI Hyperscale Data Center Power by 40%"

Efficient Computer’s Efficient Computer is 100X More Energy Efficient than Other General-Purpose Processors

I remember the heady days of the 1970s, when new and exciting 8-bit processor architectures were sprouting like metaphorical mushrooms. I’m sure that, like me, you are thinking of little beauties like the 8008 (1972), 8080 (1974), and 8085 (1976) from Intel, the 6800 (1974) from Motorola, the 6502 (1975) from MOS Technology, and the Z80 (1976) from Zilog.

However, there were many other contenders that deserve mention, such as the 8-bit PPS-8 (1974) from Rockwell International, which … Read More → "Efficient Computer’s Efficient Computer is 100X More Energy Efficient than Other General-Purpose Processors"

A Blob No More

My head hurts. As usual, I’ve been floundering around in embedded space (where no one can hear you scream). And as a result, I’ve been introduced to something with so many possibilities and potentialities that I don’t know whether I’m coming or going or doing something else entirely.

I was just chatting with Rolf Segger, the Founder, Owner, and Chief Strategist, and Dirk … Read More → "A Blob No More"
