When we consider the current application domains of RISC-V chips is predominantly focused on low-computing power MCU markets and IoT domains with minimal ecosystem dependencies. This approach is understandable, yet RISC-V still has untapped potential in the x86 and ARM ecosystem markets. For RISC-V, the high-performance domain represents a highly valuable market segment, pivotal to its commercial development, and an essential indicator of its integration into the mainstream chip architecture.
RISC-V is continuously evolving, embracing advanced manufacturing processes, enhanced performance, and higher-end applications. In the realm of high-end servers, RISC-V demonstrates a promising trajectory. The annual ARK Big Ideas 2021 report, regarded as a tech investment "bible", predicts that the combined market share of ARM and RISC-V in the server market will rise from zero in 2020 to 71% by 2030. Furthermore, ARM and RISC-V have the potential to replace Intel x86 in the cloud computing sector. By 2030, CPU revenues are projected to reach $19 billion, while server revenues are estimated to reach $100 billion, resulting in a compound annual growth rate of 45%. These projections illustrate the vast market prospects for RISC-V.
However, enabling RISC-V chips to be employed in diverse fields extends beyond the mere stacking of advanced manufacturing processes and high-performance capabilities. Equally important is the need for a richer and more robust software and hardware ecosystem. Presently, the efficiency of compilation and the availability of verification environments pose as barriers, hindering widespread developer and community involvement in the construction of the RISC-V ecosystem.
Previously, software or systems based on the RISC-V architecture could only be compiled and developed within virtual machines. This reliance on cross-compilation toolchains, which convert source code from the development host into executable files compatible with the RISC-V instruction set, introduced various problems and limitations, including compatibility issues, performance losses, and debugging difficulties.
However, the introduction of the high-performance RISC-V workstation, Milk-V Pioneer, revolutionizes the accessibility of native RISC-V development and compilation environments at a lower cost. This breakthrough offers numerous significant advantages:
Enhanced Performance and Efficiency
Local compilation enables code to be directly compiled and executed on the RISC-V workstation, leveraging the hardware resources and features of the workstation to their fullest extent. This eliminates performance losses associated with cross-compilation, accelerates the compilation and execution processes, and ultimately speeds up the development cycle.
Improved Compatibility and Reliability
Local compilation eliminates compatibility issues that may arise during cross-compilation across different platforms. Developers can directly compile and test software on the target platform, ensuring stability and reliability on that particular platform.
Simplified Debugging and Optimization
A local compilation environment provides a more direct and effective approach to debugging and optimization. Developers can debug in a real hardware environment, enabling more accurate analysis and issue resolution. Additionally, local compilation allows for the utilization of performance analysis tools and debuggers specific to the target platform, facilitating better optimization and fine-tuning of software performance.
Driving RISC-V Ecosystem Development
By providing high-performance RISC-V workstations and local compilation environments, the development and maturity of the RISC-V ecosystem are significantly promoted. Developers can more conveniently develop and test RISC-V software and systems, thereby driving the adoption and application of RISC-V in various fields.
The introduction of the Milk-V Pioneer product series marks a milestone in the RISC-V software ecosystem. It addresses a longstanding challenge in the process of operating system distribution construction, which relied on virtual machines and lengthy compilation times. As a result, it significantly reduces the entry barriers for RISC-V ecosystem development and propels the entire RISC-V software ecosystem to new heights.
The Pioneer comes with a 64-core high-performance RISC-V chip on board, SOPHON SG2042, providing users with powerful processing performance.
The SG2042 server chip is based on the RISC-V instruction set architecture (ISA) and features a 64-core server-grade chip designed to meet high-performance computing needs. It offers scalability, flexibility, and customization, with integrated circuits including high-speed cache (L3Cache 64 MB), memory controller (4 DDR4-3200), network interface, and PCI Express® controller (x32 PCI Express Gen4.0), supporting general-purpose operating systems such as Linux. The SG2042 has a clock speed of 2 GHz and a design consisting of 16 clusters, each containing 4 RISC-V cores, with each core featuring L1-D 64 KB and L1-I 64 KB. Each cluster shares a design of L2 1 MB. The L3 System cache has a capacity of 64 MB. The SG2042 supports interconnect between two chips via CCIX and has 4 DDR4-3200 controllers, supporting RDIMM, ECC, and UDIMM. The chip also has 32x PCI E Gen 4.0 interfaces, integrated eMMC5.1, SDIO 3.0, SPI x2, I2C x4, UART x4, and gigabit Ethernet MAC.
These features make Milk-V Pioneer ideal for use as a RISC-V compiled workstation or as a high-performance server.
The Pioneer Board is designed with a diverse range of powerful and versatile interfaces, making it an ideal choice for various applications and use cases. The onboard interfaces include 2x RJ45 2.5 G for fast network connectivity, 5x SATA 3.0 6 Gbps for high-speed storage devices, 2x M.2 M Key (PCIe 3.0 x4) and 1x M.2 E Key (PCIe 3.0 x1 + USB 2.0) for flexible SSD and expansion card options, 8x USB 3.2 10 Gbps for ultra-fast data transfers. These comprehensive connectivity options provide users with the flexibility to create tailored solutions and maximize the potential of the Pioneer Board for various computing needs.
On the firmware, thanks to the efforts of the R&D team of Sophgo, the latest OpenSBI mainline code has been successfully booted on the system.
Yixun Lan, the developer of Gentoo, completed the basic porting of U-Boot, and now we can use U-Boot to boot the OS instead of Linuxboot.
As SG2042 is a server-level chip, UEFI/ACPI is usually used as the firmware on servers. The engineers from Sophgo are also working hard to port EDK2 so that it will be possible to boot the platform. The boot flow chart can be seen in the image above.
The Pioneer Board supports a wide variety of Linux distributions, allowing you as a user to choose the operating system that best suits your needs and preferences. This compatibility provides you with the flexibility to take advantage of the diverse range of features, tools, and software packages available in different Linux distributions. By supporting various Linux systems, our product enables you to tailor your computing experience according to your specific use cases and requirements, ultimately enhancing your productivity and satisfaction.
