The DC-ROMA Laptop II has undergone comprehensive upgrades in both hardware and software, offering enhanced computing power and energy efficiency, as well as extensive system and tool support for developers.
Hardware Upgrades
SoC Upgrade: From 4-Core to 8-Core
The DC-ROMA Laptop II features the new SpacemiT Key Stone™ K1 SoC, delivering substantial performance improvements. According to the report from SpacemiT, the K1’s single-core performance is 30% higher than that of the ARM Cortex-A55, significantly reducing computing costs for equivalent tasks. Additionally, the K1’s power consumption is only 60%-80% of the ARM Cortex-A55, making it more efficient.
K1 supports RVA22 Profile and 256-bit RVV 1.0 standard, providing 2 times SIMD parallel processing capability than ARM NEON.
In terms of AI computing, the K1 supports all mainstream AI algorithms, from AlexNet to Llama-2-7b, enabling seamless integration with all major AI ecosystems and ensuring the successful deployment of AI models. Compared to its predecessor, the K1 improves single-core performance by 10% and multi-core performance by 150%, nearly doubling overall multi-core performance.
Developer Interface
The DC-ROMA Laptop II includes a customized 8-pin developer interface supporting I2C, UART, and PWM functions, simplifying hardware development and debugging for developers. The UART serial port can typically be configured to output the Linux startup command line console.
Software Support

RISC-V Native Development and Compilation
RISC-V native compilation simplifies developers’ work by providing ease of development and testing with immediate feedback and a simplified toolchain. It ensures accurate performance optimization using the actual target hardware and consistency in the development environment, eliminating compatibility issues.
Native compilation streamlines the workflow by allowing direct development on the RISC-V system, enhances learning and familiarity with the architecture, and reduces overhead by eliminating the need for emulators or simulators. This approach offers a more efficient and reliable development process with better integration and performance profiling capabilities.
C Native Development
- Edit a C file with a text editor and save it, e.g., hello.c.
- Run gcc hello.c -o hello to compile and generate the executable binary hello.
- Run ./hello to see the output “Hello, World!” as expected.
Python Native Development
- Edit a Python file with a text editor and save it, e.g., testyear.py.
- Run the program with the command python3 testyear.py.
- Enter 2022, and it correctly prompts “2022 is not a leap year.”
Python + PyQt5 Native Development
- Edit a Python file with a text editor and save it, e.g., Firstwin.py.
- Run the program with the command python3 Firstwin.py.
- The “Hello pyQt5” window pops up as expected.
