Intel will add deep-learning instructions to its processors
Some of the latest Intel processors support the AVX-512 family of vector instructions. These instructions operate on blocks of 512 bits (or 64 bytes). The benefit of such wide instructions is that even without increasing the processor clock speed, systems can still process a lot more data. Most code today operators…

Epiphany-V: A 1024-core 64-bit RISC processor
I am happy to report that we have successfully taped out a 1024-core Epiphany-V RISC processor chip at 16nm. The chip has 4.5 Billion transistors, which is 36% more transistors than Apple’s latest 4 core A10 processor at roughly the same die size. Compared to leading HPC processors, the chip demonstrates an 80x…

A tale of an impossible bug: big.LITTLE and caching
When someone says multi-core, we unconsciously think SMP. That worked out well for us until recently when ARM announced big.LITTLE. ARM’s big.LITTLE architecture is the first mass produced AMP architecture and as we’ll see next, it raises the bar for how hard multi-core programing is.
