Bit-Brick K1 SBC leverages AI computing with RISC-V CPU

A Chinese embedded systems company, Bit Brick, has announced the launch of the Bit-Brick K1, a single-board computer that leverages open-source implementations of the RISC-V instruction set architecture (ISA). The module features the K1 RISC-V application processor developed by spacemiT, which is said to be the first RISC-V AI CPU supporting the RVA22 Profile and the 256-bit RVV 1.0 standard, providing twice the SIMD parallel processing capability compared to Neon.

According to the company, the Bit-Brick K1 single-board computer has an open-source design with up to eight X60 RISC-V processor cores, adhering to the RISC-V 64GCVB architecture and integrating AI computing capabilities. Bit Brick claims that the computing power of a single-core CPU exceeds that of the ARM A55 by more than 30 percent. Furthermore, the RISC-V microarchitecture design is reported to reduce power consumption by 20 percent compared to ARM chips under comparable load conditions.

To leverage AI computing capabilities with spacemiT, the single-board computer integrates scalar computing based on the RISC-V 64GCB standard instructions, vector computing utilizing RISC-V Vector 1.0 standard instructions, and matrix computing power through dedicated acceleration instructions found in the RISC-V custom-1 coding space.
