Last year, ARM released the Cortex A73 and Mali G71 architectures at Tech Day. This year, they will introduce their successors, the A75 and A55 architectures, as well as the Mali G72 architecture. On May 26, news emerged that foreign media successfully uncovered ARM’s official PPT, fully leaking relevant information about these three new architectures. … Read more
Arm Selected Courses – Focus on ARM and TEE 1. Cortex-X925 The Cortex-X925 core is a high-performance, low-power product based on the Armv9.2-A architecture. The Armv9.2-A architecture extends the Armv8-A architecture, encompassing Armv8.7-A. The Cortex-X925 core is integrated within the DSU-120 DynamIQ™ cluster. It connects to the DynamIQ™ Shared Unit-120, which serves as a complete … Read more
Recently, Zhiqu Dog introduced ARM’s brand new Cortex-A75 and Cortex-A55 architectures, as well as the Mali-G72 GPU (see “ARM’s Breakthrough! Mobile Processors Will Transform in a Few Months Because of Them!”). However, the article involved a lot of technical terms, and some readers commented that they found it “hard to understand.” No worries, ARM’s designers … Read more
