Jussi Kivilinna 2fd1bb8f02 Add option to use smaller AES tables (table sizes reduced by 6144 bytes) ... This patch adds MBEDTLS_AES_SMALL_TABLES option to reduce number of AES look-up tables and thus save 6 KiB of memory. Enabling this option cause performance hit MBEDTLS_AES_SMALL_TABLES of ~7% on ARM and ~15% on x86-64. Benchmark on Cortex-A7 (armhf): Before: AES-CBC-128 : 14394 Kb/s, 0 cycles/byte AES-CBC-192 : 12442 Kb/s, 0 cycles/byte AES-CBC-256 : 10958 Kb/s, 0 cycles/byte After: AES-CBC-128 : 13342 Kb/s, 0 cycles/byte AES-CBC-192 : 11469 Kb/s, 0 cycles/byte AES-CBC-256 : 10058 Kb/s, 0 cycles/byte Benchmark on Intel Core i5-4570 (x86_64, 3.2 Ghz, no turbo): Before: AES-CBC-128 : 215759 Kb/s, 14 cycles/byte AES-CBC-192 : 190884 Kb/s, 16 cycles/byte AES-CBC-256 : 171536 Kb/s, 18 cycles/byte After: AES-CBC-128 : 185108 Kb/s, 16 cycles/byte AES-CBC-192 : 162839 Kb/s, 19 cycles/byte AES-CBC-256 : 144700 Kb/s, 21 cycles/byte		2017-06-07 15:29:31 +01:00
