Salen a la luz un puñado de páginas escritas por Albert Einstein
Un puñado de reflexiones personales y científicas de Albert Einstein, muchas escritas entre 1944 y 1948, han salido a la luz por parte de la Universidad Hebrea de Jerusalén. Einstein fue uno de los padres fundadores de esta universidad y legó sus escritos personales y científicos a la misma, lo que condujo a la fundación de los Archivos de Albert Einstein: 80.000 manuscritos, artículos de correspondencia, fotografías y materiales)…

[ From Linley Newsletter ] Synaptics Pairs Ears With Brains

[ From Linley Newsletter ] Synaptics Pairs Ears With Brains
Partly to protect privacy, and partly to reduce network latency, the newest embedded processors for smart speakers and other voice-activated devices are adding AI acceleration to offload speech recognition from the servers at distant data centers. After listening closely to this growing customer base, Synaptics is sampling its new AudioSmart AS-3xx SoCs for voice assistants.
By Tom R. Halfhill
The first version to arrive is the AS-371, which began sampling in January. Three derivatives are slated to sample this month; all should begin production this year. The AS-371 has four Arm Cortex-A53 CPUs for application software, a proprietary security processor, and a proprietary neural-network engine for speech recognition. Three models add a low-power Cortex-M33 core for always-on wake-word awareness but replace the neural engine with a Cadence Tensilica HiFi 4 DSP. The low-end model substitutes a single Cortex-M33 for the Cortex-A53s in the other chips; the M33 is a low-power controller that runs a small RTOS instead of Linux or Android.
Some Google Home products already employ Synaptics SoCs, and Microsoft’s Cortana smart speaker has a Synaptics AudioSmart DSP for far-field voice recognition. So does Netgear’s Orbi Voice, a smart speaker that features Amazon Alexa voice control. It can pair with the Orbi Mesh Wi-Fi System, an 802.11ac router with repeaters that extend the network’s range throughout a large house or office.
All these products have Synaptics chips that are less integrated than the AS-371. It can combine the Wi-Fi repeater and smart-speaker functions in one device by adding an 802.11 radio attached to its PCI Express interfaces. As an established supplier of voice DSPs and controllers for touchpads and fingerprint sensors, Synaptics is a logical choice for advanced user interfaces.

[ From Linley Newsletter ] Arm Floats New ISA With Helium

[ From Linley Newsletter ] Arm Floats New ISA With Helium
The Arm v8.1-M ISA includes the new M-Profile Vector Extension (MVE), comprising a set of features (code-named Helium) that will enable future Cortex-M CPUs to perform 128-bit vector/SIMD operations. Helium is functionally similar to Cortex-A’s Neon vector/SIMD extensions, but just as helium is a lighter noble gas than neon, Arm v8.1-M can scale to fit the 32-bit data paths and register files in smaller Cortex-M CPUs. Lead customers received early access in 2018, but the company has withheld the names and other details of the initial CPUs based on the new ISA. It expects the first silicon to hit the market in 2021, however.
By Mike Demler
Helium extends the Arm v8.0-M mainline architecture, which currently appears in Cortex-M33 as well as the security-enhanced Cortex-M35P. The mainline ISA includes DSP/SIMD and FPU options missing from the baseline ISA in the smaller Cortex-M23. In the updated ISA, Helium (like Neon) uses the FPU registers for 128-bit vector processing. But whereas the Aarch64 architecture in Arm v8-A implements 32×128-bit registers in each Neon unit, Arm v8.1-M avoids expanding die area by reorganizing the 32×32-bit FPU registers into just 8×128-bit vector registers.
Arm v8.1-M adds approximately 150 new instructions to Cortex-M CPUs, including complex-math operations, INT8 vector dot products, lane predication, loop predication, and gather/scatter access to load/store memory. Machine-learning performance increases by 15x for matrix-math operations, and FFTs run 5x faster relative to Arm v8.0-M CPUs. Customers will appreciate the performance boost from the new vector/SIMD extensions, which enable them to employ a familiar tool chain for their lightweight DSP and neural-network applications. But the first Helium cores won’t appear until 2021, leaving plenty of time for competitors to update their ISAs.

Researchers suggest LISA should be able to see ultralight bosons near supermassive black holes [ if they exist ]
An international team of researchers has found evidence that suggests the Laser Interferometer Space Antenna (LISA) should be able to “see” ultralight bosons if they exist. In their paper published in the journal Nature Astronomy, the group describes calculations they made to assess whether ultralight boson clouds forming outside of the event horizons of black holes could be detected by LISA, and what they found…

Canonical informed Softpedia today about a new infographic they prepared for developers interesting in building or packaging their apps as Snaps using the Snapcraft utility. Dubbed “Snapcraft for developers,” the infographic aims to show application developers how simple is to build Snaps, Canonical’s universal binary format for distributing Linux apps on Ubuntu and across a multitude of GNU/Linux distributions. The infographic also reveals that Snaps see more than 3 million installs per month from over 2,000 developers who use Snapcraft to publish their Snaps in the Snap Store…

Encuentran herbicida [ Glifosato ] en cervezas y vinos, pero no hay motivo [ conocido o razonable ] para que esté ahí
Uno de los placeres que se pueden dar las personas que trabajan toda la semana es ir por un buen trago. Ya sea una cerveza con amigos o un vino con tu pareja, estas bebidas son parte de nuestras vidas. Como seguramente ya viste en el título, se encontraron químicos que pueden afectar la salud de quien los consuma. Estos químicos son herbicidas, utilizados para eliminar hierbas y arbustos que pueden afectar la producción de alimentos. Estos químicos fueron encontrados en muchos tipos de cervezas y vinos a nivel internacional. Dada la elaboración de cervezas orgánicas y por lo ingredientes de ciertos vinos, no deberían estar cerca de los herbicidas…
