Intel's new Alderlake consumer desktop CPUs use more power and little-big core design
to seemingly benchmark faster than AMD chips. I do not understand why increasing
power use for significant executiion speed improvement is not good. Here are some
I am working on an argument that uses normal computer
integer unit type primitives to calculate algorithm complexity
such as unit multiply and the ability to index arrays and bit strings.
It changes complexity results. Wide multiply by table
look up can't be a primitive because the table...
There has been recent advances in algorithms to translate protein
sequences into protein structure. As usual Google is calling its
program Alphafold a great AI success. Reality is that it is just good
application programming using physical theories from molecular bonding
area. Program is...
I think the new US Biden administration China rules contradict the discussions on Semiwiki. My view is that Biden is right. Everyone benefits from a world wide electronics industry. US sanctions are only to stop US investments in Chinese miltary linked companies. It does include no US...
Samsung Venture Fund has just invested in a quantum computer (QC) start up in Maryland called IonQ. Here is one story:
IonQ is interesting because its QCs are large and use well understood...
My thinking on this was triggered by an interesting discussion on
Slashdot speculating on how the Chinese icensed from AMD X86
processor will work.
I do not understand the ARM processor in detail. Although I did spend
some time thinking about porting CVC Verilog simulator to generate
I studied physics as a Stanford undergraduate back in
the late 1960s. I knew William Shockley from taking his Freshman
seminar. I noticed various recent commemorations of the founding
of Shockley Semiconductor. I knew a different Shockley than the
current mythology and think the book "Broken...
John von Neumann in the 1950s already considered abstract models of computers in designing the von Neumann architecture that is used to build modern computers. The problem is that although Turing Machines are universal, they are slow because they lack random access and bit accessing...
This appeared in today's Financial Times Chess column:
"The US champion and world No. 2 unleashed a brilliant
opening novelty, which incendently showed the limitations
of the most powerful computers."
Does anyone know anything more about this? I do
not understand chess, just enough to sort of...
There is interesting PR from IBM research press release on new chip
to detect cancer. Claim is that chips using bio-assay can detect
cancer. Here is a URL for one story:
IBM Lab on Chip Detects Cancer | EE Times
Area is interesting because there is a very complex bio-marker
It is the slow holiday season so I thought I would comment on
a recent EE Times story and a recent EDA Cafe story. The first
is about an MIT claim of making an advance in Quantum magnetism.
The claim should be labeled an advance in "solid state electrodynamics"
because discovery is of a new...
This is to amplify Andrew's answer to the X propagation discussion
and explains why we think only simulation can find gate level X's
handled incorrectly by normal Verilog semantics especially X propagation
problems that involve edges...
