Cell phones have to handle telecommunications and audiovisual processing while maximizing battery life. Digital Signal Processors, or DSPs, use specialized hardware to offload these tasks from the CPU which lowers power usage. From an old Qualcomm presentation on Snapdragon 800, showing Hexagon's evolution. Note the large blocks of L2/TCM SRAM Qualcomm's Hexagon has a long…
Artificial intelligence poses the most risk when it is embedded in a centralized, tightly coupled organization. But it can facilitate decentralization too.
Daniel Vetter put together a pair of intriguing blog posts entitled Locking Engineering Principles and Locking Engineering Hierarchy . These appear to be an attempt to establish a set of GPU-wide or perhaps even driver-tree-wide concurrency coding conventions. Which would normally be none of my…
Researchers from the Technical University of Munich (TUM) have designed and commissioned fabrication of chip intended to implement so-called post-quantum
Date Time Post-quantum chip with hardware trojans A team at the Technical University of Munich (TUM) has designed and commissioned the production of a computer chip that implements post-quantum cryptography very efficiently. Such chips could provide protection against future hacker attacks using quantum computers. The researchers also incorporated hardware trojans in the chip in order to study methods for detecting this type of “malware from the chip factory”. Hacker attacks on industrial operations are no longer science fiction – far from it. Attackers can steal information on product...
