Embedded Boards: Pioneering the Next Wave of Innovation

Intel Reveals New 288-Core Sierra Forest CPU, Specifically Designed for High-Density Servers

The 288-core CPU, as part of the Sierra Forest lineup, promises to deliver unparalleled processing capabilities for data-intensive tasks, while the compatibility with the Birch Stream platform opens the door for advanced server configurations and scalability, setting the stage for more efficient and powerful computing solutions.

This move reflects Intel’s dedication to innovation and its ongoing efforts to address the evolving needs of diverse sectors within the technology landscape, promising exciting developments on the horizon for both consumers and enterprise customers.

AMD Introduces EPYC 8004-Series 'Siena' CPUs

Siena is comprised of the same 5nm Zen 4c core complex die (CCD) chiplets as Bergamo, which are paired with AMD’s one and only 6nm EPYC I/O Die (IOD). As a result, the EPYC 8004 family isn’t so much new hardware as it is a new configuration of existing hardware – about half of a Bergamo, give or take.

Underscoring the entry-level nature of the Siena platform, Siena ships with fewer DDR5 memory channels and fewer I/O lanes than its faster, fancier counterpart.

Sheba Microsystems Launches Revolutionary MEMS Autofocus Actuator for Active Athermalization in Embedded Vision Cameras

The first-of-its-kind solution tackles the long-standing industry problem of embedded vision cameras’ inability to maintain image quality and focus stability during temperature fluctuations as optics undergo thermal expansion. The MEMS Autofocus Actuator for Active Athermalization in Embedded Vision Cameras can be used in automotive, action, drones, machine vision, security and surveillance, and mobile robotics.

The silicon-based MEMS actuator platform actuates the image sensor along the optical axis to compensate for thermal expansion in the optics. The weight of the image sensor represents only 2-3 % of the optical lens weight, which makes it easier to handle, enabling ultra-fast and precise autofocus performance even when temperatures fluctuate.

MEMS Autofocus and CPUs Matter Most When Every Second Counts

Whether it's snapping the perfect shot with your smartphone or ensuring the safety of autonomous vehicles, the need for lightning-fast, precise autofocus in embedded systems is undeniable.

MEMS autofocus sensors deliver incredible speed and precision to devices. MEMS autofocus technology makes it possible for delivery robots to navigate through busy city streets by perceiving its surroundings with utmost clarity.

The power behind the speed and accuracy of these systems lies in the CPUs, which are responsible for crunching data, making split-second decisions, and ensuring a seamless user experience.

The combination of MEMS autofocus and advanced CPUs empowers our devices to see, think, and act with unmatched precision and speed. It's not just about sharp photos or delivering pinpoint navigation; it's about opening new possibilities for innovation.

As they continue to evolve, we're on the cusp of an era where the future of embedded systems is bright, and MEMS autofocus and CPUs are the guiding stars lighting the way.
