SiFive designed the P870-D \u00a0specifically for workloads that benefit from high levels of parallelism over raw single-thread performance. These workloads include video streaming, web hosting, storage, and AI inference tasks\u2014areas that require efficiency, scalability, and cost-effectiveness.<\/p>\n<p style=\"text-align: start;\"><img decoding=\"async\" style=\"width: 100%;\" src=\"https:\/\/file.flywing-tech.com\/res\/article\/20240920165806586b9d42b4cd8ffe124d14647c2fad48ae87366b.png\" alt=\"\" data-href=\"\" \/><\/p>\n<p style=\"text-align: center;\"><em>SiFive processor roadmap<\/em><\/p>\n<p style=\"text-align: start;\">\n<p style=\"text-align: start;\">\u201cWhen we looked at the marketplace, people were doing whatever they could to get single-thread performance up,\u201d Ferguson said. \u201cBut as soon as you start to do that, you get to a place where performance is going up a little, and power is going up a lot. When we looked at our decision points, it was around that volume, mainstream area of data centers where we can do a better job of optimizing power and performance.&#8221;<\/p>\n<p style=\"text-align: start;\"><strong>Key Features of the P870-D Data Center Processor<\/strong><\/p>\n<p style=\"text-align: start;\">Several architectural features set the P870-D apart from other processors in the market.<\/p>\n<p style=\"text-align: start;\">First, SiFive designed the device to scale up to 256 coherent cores, a feature that aids in handling parallel processing tasks common in data centers. A distributed input-output memory management unit (IOMMU) architecture complements this scalability, enhancing the processor\u2019s ability to manage virtualized device I\/O. The distributed IOMMU allows the P870-D to eliminate bottlenecks and enhance performance to process large datasets quickly and efficiently.<\/p>\n<p style=\"text-align: start;\"><img decoding=\"async\" style=\"width: 100%;\" src=\"https:\/\/file.flywing-tech.com\/res\/article\/202409201659045945e485b2eeea5673c7a5c6bec16ce9675c185e.png\" alt=\"\" data-href=\"\" \/><\/p>\n<p style=\"text-align: center;\"><em>Building on a partnership with Arteris, SiFive will use the P870-D to lead RISC-V-based emulation systems with Arteris Ncore compliance. <\/em><\/p>\n<h5 style=\"text-align: center;\"><\/h5>\n<p style=\"text-align: start;\">\n<p style=\"text-align: start;\">Another major feature of the P870-D is its support for the RISC-V Sv57 extension, which provides 57-bit virtual address space support. This extension allows the processor to manage large memory spaces, making handling large-scale AI training models and other memory-intensive tasks significantly more feasible.<\/p>\n<p style=\"text-align: start;\">In addition to its memory management capabilities, the P870-D integrates advanced reliability, availability, and serviceability (RAS) features. These features detect and correct errors before they can impact system performance, allowing data centers to operate continuously without downtime.<\/p>\n<p style=\"text-align: start;\">\u201cWe&#8217;ve taken a core that we announced last year called the P870, and we&#8217;ve added RAS functionality to do error detection and correction on registers,\u201d Ferguson said. \u201cWe&#8217;ve also increased the capability to scale to more CPU cores, so you can go up to 256 coherent cores.\u201c<\/p>\n<p style=\"text-align: start;\">Moreover, the P870-D is designed with power efficiency in mind. SiFive has implemented various power management features, including dynamic voltage and frequency scaling (DVFS) and idle power modes, to minimize power consumption without sacrificing performance.<\/p>\n<p style=\"text-align: start;\"><strong>Advanced Protocol Support<\/strong><\/p>\n<p style=\"text-align: start;\">One of the P870-D&#8217;s defining features is its comprehensive <a href=\"https:\/\/www.flywing-tech.com\/blog\/processor-companies-weigh-into-ai-development-with-software-support\/\">support for advanced<\/a> protocols, including AMBA Coherent Hub Interface (CHI) and Compute Express Link (CXL), both of which enhance the processor\u2019s scalability and interoperability within complex system architectures.<\/p>\n<p style=\"text-align: start;\"><img decoding=\"async\" style=\"width: 100%;\" src=\"https:\/\/file.flywing-tech.com\/res\/article\/2024092016592259224ea7b0f5843ef3e4df05e85fb2a62a73b4b9d.png\" alt=\"\" data-href=\"\" \/><\/p>\n<p style=\"text-align: center;\"><em>Scalable subsystems using the P870-D. <\/em><\/p>\n<h5 style=\"text-align: center;\"><\/h5>\n<p style=\"text-align: start;\">\n<p style=\"text-align: start;\">AMBA CHI is an open protocol that enables cohesive scaling of the number of clusters within a system. By supporting AMBA CHI, the P870-D enables data center architects to scale their systems up to 256 coherent cores while maintaining high data integrity and performance. This scalability handles the parallel processing demands of modern data centers, where multiple tasks must be executed simultaneously without bottlenecks. Using a standard CHI bus also means that the P870-D can easily integrate with existing systems, reducing the time and cost of developing custom interconnects.<\/p>\n<p style=\"text-align: start;\">Conversely, CXL is a protocol that facilitates coherent memory access between CPUs, accelerators, and other devices. The P870-D\u2019s support for CXL allows users to create heterogeneous systems where different processing elements can share memory resources efficiently. This is particularly important for AI workloads, where accelerators and general-purpose CPUs must work cohesively.<\/p>\n<p style=\"text-align: start;\"><strong>A Boon for Data Centers<\/strong><\/p>\n<p style=\"text-align: start;\">With the P870-D, SiFive balances performance and power over raw performance alone.
