Kernel characteristics.

Kernel Name	Description
Matrix Multiply (MM)	Computes multiplication of two arrays (used in many applications). Array sizes are 1024 × 1024 or 512 × 512. Data type is 32-bit integer.
Blowfish encrypt/decrypt	Blowfish is a symmetric block cipher with a variable length key. It is widely used for domestic and exportable encryption.
Adpcm encode/decode	Adaptive Differential Pulse Code Modulation (ADPCM). It is a variation of the standard Pulse Code Modulation (PCM).
AES	Advanced Encryption Standard (AES) is a block cipher with option of 128-, 192-, and 256-bit keys and blocks.
TDES	TDES applies the Data Encryption Standard (DES) cipher algorithm three times to each data block.
SHA	SHA is the secure hash algorithm. It is often used in the secure exchange of cryptographic keys and for generating digital signatures.
