+
+# AES for ARMv4
+
+# January 2007.
+
+# Code uses single 1K S-box and >2 times faster than code compiled
+# with gcc-3.4.1. This is thanks to unique feature of ARMv4 ISA, which
+# allows to merge logical or arithmetic operation with shift or rotate
+# in one instruction and emit combined result every cycle. The module
+# is endian-neutral. The performance is ~42 cycles/byte for 128-bit
+# key.
