U7 Series
U74-MC
The SiFIve U74-MC Standard Core is a high performance RISC-V application processor, capable of supporting full-featured operating systems such as Linux. The U74-MC has 4x 64-bit U74 cores and 1x 64-bit S7 core -- providing high performance with hard real-time determinism.
This U74-MC is ideal for applications requiring high-throughput performance with real-time guarantees (e.g., Enterprise Storage, Wireless/Wireline Networking, 5G Baseband Processors, SLAM Processors, Sensor Fusion, etc.)
