Hot Chips cooks next-gen processors, wireless, design tech

The approach also is an ideal design for virtual reality goggles that use one GPU per eye, said Macri showing a small form factor liquid-cooled system.

The eight-year long programme that led to Fury was "the longest project in my career," he said.

In an impromptu discussion at the lunch hour, Macri noted business hurdles were as big as technical ones. Executives at both AMD and SK Hynix had to be convinced to spend money on the risk project, he said.

Many more horizons

MIAOW team

The MIAOW team (clockwise from upper left) includes Raghu Balasubramanian, Karu Sankaralingam, Vinay Gangadhar and Cherin Joseph.

One conclusion I took away from Hot Chips this year is there is plenty of work ahead in microprocessor design and many smart young engineers learning to do it. For example, the MIAOW design team from the University of Wisconsin at Madison (above) showed the first open source general-purpose GPU.

Similar teams of smart grad students at Berkeley showed results of their RISC-V processors (below) that are on par with commercial chips.

RISC-V chips

RISC-V chips (yellow) compare favourably with ARM chips (green) as well as MIPS and Intel processors (black and blue, respectively).

Two last tidbits: One veteran chip designer told me a new high-performance memory is in the works that will be ideal as a kind of first-level cache inside the processor package, perhaps in a 2.5D stack.

Separately an engineer from Japan's NTT Corp. described its work on a chip for H.265, the high efficiency video codec. Such chips will be key to enabling the kind of 8K television displays that will follow today's ultra high def 4K screens.

"8K is not a dream. It will be public in 2020," said the presenter indicating Japan's broadcasting plans (bottom).

8K broadcast roadmap

Japan hopes to switch on 8K broadcasts for the 2020 Olympics.
