Core Insights - Condor Computing, a subsidiary of Andes Technology, focuses on developing licensable RISC-V cores, similar to Arm and SiFive, and has prior RISC-V design experience before its establishment in 2023 [2] - The Cuzco core, to be showcased at Hot Chips 2025, is a high-performance RISC-V design featuring advanced out-of-order execution capabilities and sophisticated branch predictors, expected to outperform existing RISC-V cores like Alibaba's T-HEAD C910 and SiFive's P550 [2][6] Core Overview - Cuzco is an 8-wide out-of-order core with 256 ROB entries, targeting clock speeds of approximately 2 GHz to 2.5 GHz on TSMC's 5nm process, with a 12-stage pipeline [6][10] - The core employs a static scheduling approach to save power and reduce complexity, which does not require modifications to the ISA or compiler for optimal performance [4][10] Execution Resources - Cuzco's execution resources are grouped into multiple slices, each capable of executing all supported RISC-V instructions, allowing for easy scalability by adjusting the number of slices [33] - Each slice has a set of execution queues (XEQ) that hold micro-operations waiting for functional units, with a maximum of two micro-operations executed per cycle [33] Branch Prediction - The core utilizes a complex branch predictor, TAGE-SC-L, which efficiently manages branch predictions by selecting the most suitable history length for each branch [11][12] - Cuzco features an 8K entry branch target buffer (BTB) and a 32-entry return stack for predicting return values, with instruction fetching supported by a 64 KB instruction cache [14] Load/Store Architecture - Cuzco's load/store unit includes a 64-entry load queue, a 64-entry store queue, and a 64-entry data cache miss queue, with a maximum load bandwidth of 64B per cycle [36][38] - The L1D cache is 64 KB with an 8-way set associative design, while the L2 cache can be configured up to 8 MB, and the L3 cache is shared among eight cores [38][43] Performance and Efficiency - Cuzco's design aims to achieve high performance while maintaining low power consumption, with a focus on minimizing replay penalties and optimizing resource utilization through a time resource matrix (TRM) [23][25] - The core's architecture allows for dynamic scheduling and effective handling of cache misses through instruction replay mechanisms [50][52]
EDA行业,面临严峻挑战
半导体行业观察· 2025-09-01 01:17
Core Viewpoint - The Basilisk project, presented at Hot Chips 2025, aims to redefine the potential of open-source hardware by demonstrating a fully functional RISC-V SoC that operates on a complete Linux system, developed entirely using open-source EDA tools [2][11]. Group 1: Project Overview - Basilisk is a 34 mm² RISC-V SoC manufactured using IHP Microelectronics' open-source 130nm BiCMOS process [2]. - The project signifies a shift from viewing open hardware as an academic toy to a reliable system platform [2]. - The chip integrates a single-issue, in-order RV64GC CPU core (CVA6) with MMU, instruction/data cache, and HyperRAM controller, supporting a Linux software stack [6]. Group 2: Industry Context - Many large semiconductor companies have joined the RISC-V International Organization but have not actively supported its ecosystem, indicating a reluctance to embrace the shift towards open-source chips [2][3]. - The high costs associated with advanced node fabrication, often reaching tens of millions of dollars, lead companies to prefer proprietary suppliers that offer security and support [3]. - The current semiconductor landscape shows a clear divide, with U.S. companies sticking to familiar licensing models while challengers in China and Europe are accelerating the adoption of open processes [4]. Group 3: Technological Advancements - The project aims to demonstrate that fully open processes can achieve industrial standards through reasonable engineering investments, with future projects targeting larger scales [9]. - The use of Yosys and OpenROAD tools is highlighted as essential for proving the viability of open-source chip design [5]. - The Basilisk chip achieved a peak frequency of 102 MHz at 1.64 V and demonstrated high energy efficiency at lower voltages, indicating the potential of open-source designs to leverage voltage scalability [7]. Group 4: Strategic Implications - The support for the Basilisk project by the Swiss government and research institutions reflects a broader trend of viewing investment in open silicon as a matter of strategic sovereignty [11]. - The emergence of open-source EDA tools presents both a challenge and an opportunity for existing companies, as universities can now train engineers in these processes, potentially leading to innovation in commercial tools [9].
