+The SiFive U54 Standard Core is a single-core instantiation of the world’s first RISC-V application processor, capable of supporting full-featured operating systems such as Linux.
+
+The U54 is ideal for low-cost Linux applications such as IoT nodes and gateways, point-of-sale, and networking.
+
+This target features:
+
+- 1 RV64GC U54 Application Core
+- 16KB L1 I-cache with ECC
+- 16KB L1 D-cache with ECC
+- 8 Region Physical Memory Protection
+- 48 Local Interrupts per core
+- Sv39 Virtual Memory support with 38 Physical Address bits
+- Integrated 128KB L2 Cache with ECC
+- Real-time capabilities
+- CLINT for multi-core timer and software interrupts
+- PLIC with support for up to 128 interrupts with 7 priority levels
+- Debug with instruction trace
