ARM: The Future of AI Infrastructure Arm has joined the Open Compute Project Foundation (OCP) Board of Directors to help define open standards for AI data centers in 2025. AI is boosting chiplet adoption and pushing the IC design ecosystem from a single-vendor to a multi-vendor model. Arm Total Design(ATD) ecosystem adds new capabilities to advance chiplet supply chain for AI innovation, tripling in size since its 2023 launch. The High-Performance Arm V3 Platform Performance-Optimized and Validated by ARM. ...

Advanced Microcontroller Bus Architecture(AMBA) 2024-01-17 AMBA 5 is the latest generation of the freely available AMBA protocol specifications. It introduces the Coherent Hub Interface (CHI) architecture, which defines the interfaces to connect fully coherent processors and high-performance interconnects. AMBA 5 also introduces the AXI5, ACE5 and AHB5 protocols, which extend prior generations to include a number of performances and scalability features, and to align and complement CHI. AMBA 5 Protocols ...

Some metrics for ARM Mali performance analysis in DS-5 Streamline or MGD. DS-5 Streamline Mali-470 (Utgard) GPU Bandwidth = (Words read, master + Words written, master) * Bus Width Overdraw = Fragments Passed Z/stencil count * Number of Cores / Resolution * FPS GPU Bandwidth = (38342943+38661456) * (128/8) = 1232070384 bytes/s = 1174.99 MB/s Overdraw = (79194586+79152584+79112550+79117609)/(1920x1080) = 152.67 Mali-T820 (Midgard) Job Slots JS0: fragment shading. JS1: vertex, geometry, compute, and tiling. JS2: vertex, geometry, and compute. Fragment Percentage = (JS0 Active / GPU frequency) * 100 Vertex percentage = (JS1 Active / Frequency) * 100 Load Store CPI = Full Pipeline issues / Load Store Instruction Words Completed GPU Bandwidth = (External read beats + External write beats) * Bus Width Overdraw = Fragment Threads Started * Number of Cores/ Resolution * FPS ...
