+The SiFive E34 Standard Core adds single-precision floating-point to the SiFive E31 Standard Core, the world’s most deployed RISC-V core. The E34 enables advanced applications which require hardware floating-point capabilities such as signal processing and motor control.
+
+This core target is suitable with Verilog RTL for verification and running application software building on top of freedom-metal libraries. The target supports:
+
+- 1 hart with RV32IMAFC core
+- 4 hardware breakpoints
+- Physical Memory Protection with 8 regions
+- 16 local interrupts signal that can be connected to off core complex devices
+- Up to 127 PLIC interrupt signals that can be connected to off core complex devices, with 7 priority levels

+The SiFive S54 Standard Core is a 64-bit embedded processor that is fully-compliant with the RISC-V ISA. It adds support for the F and D standard extensions, which provide the S54 with double-precision floating-point capabilities.
+
+The S54 is ideal for demanding applications such as avionics, signal processing, and industrial automation.
+
+This core target is suitable with Verilog RTL for verification and running application software building on top of freedom-metal libraries. The target supports:
+
+- 1 hart with RV64IMAFDC core
+- 4 hardware breakpoints
+- Physical Memory Protection with 8 regions
+- 16 local interrupts signal that can be connected to off core complex devices
+- Up to 255 PLIC interrupt signals that can be connected to off core complex devices, with 7 priority levels
