C-K1BA Introduction
Chapter 1 Product Overview
The C-K1BA V1.0 core board uses the RISC-V SpacemiT X60 octa-core processor, equipped with the Harmony system, with a main frequency of up to 1.6GHz, super performance, and rich interfaces. It uses IMG BXE-2-32@819MHz GPU, 32KB SLC, supports 4K, H.265/H.264 hardware decoding, and is first-class in both running points and decoding. It is your new choice for human-computer interaction and industrial control projects.
1.1 Scope of application
C-K1BA V1.0 is a K1 eight-core processor core board based on the iterative space-time RSIC-V architecture. It is widely used in many fields such as smart display terminal products, video terminal products, industrial automation terminal products, etc.
1.2 Product Features
- RSIC-V is an open source architecture that is self-controlled and designed with domestically produced industrial components.
- It uses 4 groups of 80-pin BTB interfaces to bring out all pin functions, making it convenient and flexible to expand the design.
- It integrates PCIe2.0, dual-channel GMAC, SDIO, I2C, PWM, UART, and GPIO interfaces to meet the requirements of various peripherals on the market.
- Supports dual-screen display. HDMI supports a maximum resolution of 1920 1080, and MIPI supports a maximum resolution of 1920 1080.
- It comes with a deep neural network unit (NPU) with a performance of up to 2.0 TOPS, which can meet the needs of deep learning projects.
