+This directory contains several versions of femtorv32, that I'm using
+for testing different features and influence on timings:
+- testdrive_RV32IM:      tachyon core (with two execute cycles) with M extension
+- testdrive_RV32IM_simF: M extension, F decoder and simulated FPU (works only with Verilator)
+- testdrive_RV32IMF:     M and F extensions
+
+I recommend using the other cores instead.
