# CBC encrypt case. On Cortex-A57 parallelizable mode performance
# seems to be limited by sheer amount of NEON instructions...
#
+# April 2019
+#
+# Key to performance of parallelize-able modes is round instruction
+# interleaving. But which factor to use? There is optimal one for
+# each combination of instruction latency and issue rate, beyond
+# which increasing interleave factor doesn't pay off. While on cons
+# side we have code size increase and resource waste on platforms for
+# which interleave factor is too high. In other words you want it to
+# be just right. So far interleave factor of 3x was serving well all
+# platforms. But for ThunderX2 optimal interleave factor was measured
+# to be 5x...

+# Optimization is implemented by loop unrolling and interleaving.
+# Commonly, we choose the unrolling factor as 5, if the input
+# data size smaller than 5 blocks, but not smaller than 3 blocks,
+# choose 3 as the unrolling factor.
+# If the input data size dsize >= 5*16 bytes, then take 5 blocks
+# as one iteration, every loop the left size lsize -= 5*16.
+# If 5*16 > lsize >= 3*16 bytes, take 3 blocks as one iteration,
+# every loop lsize -=3*16.
+# If lsize < 3*16 bytes, treat them as the tail, interleave the
+# two blocks AES instructions.
+# There is one special case, if the original input data size dsize
+# = 16 bytes, we will treat it seperately to improve the
+# performance: one independent code block without LR, FP load and
+# store, just looks like what the original ECB implementation does.

+# Performance in cycles per byte.
+# Processed with AES-XTS different key size.
+# It shows the value before and after optimization as below:
+# (before/after):
+#
+# AES-128-XTS AES-256-XTS
+# Cortex-A57 3.36/1.09 4.02/1.37
+# Cortex-A72 3.03/1.02 3.28/1.33
+
+# Optimization is implemented by loop unrolling and interleaving.
+# Commonly, we choose the unrolling factor as 5, if the input
+# data size smaller than 5 blocks, but not smaller than 3 blocks,
+# choose 3 as the unrolling factor.
+# If the input data size dsize >= 5*16 bytes, then take 5 blocks
+# as one iteration, every loop the left size lsize -= 5*16.
+# If lsize < 5*16 bytes, treat them as the tail. Note: left 4*16 bytes
+# will be processed specially, which be integrated into the 5*16 bytes
+# loop to improve the efficiency.
+# There is one special case, if the original input data size dsize
+# = 16 bytes, we will treat it seperately to improve the
+# performance: one independent code block without LR, FP load and
+# store.
+# Encryption will process the (length -tailcnt) bytes as mentioned
+# previously, then encrypt the composite block as last second
+# cipher block.
+# Decryption will process the (length -tailcnt -1) bytes as mentioned
+# previously, then decrypt the last second cipher block to get the
+# last plain block(tail), decrypt the composite block as last second
+# plain text block.
