Discretix Cryptographic Engines
Discretix cryptographic engines are widely deployed in leading
system-on-chip solutions. Discretix provides highquality,
ready-to-use cryptographic engines, to support variety of
applications. Included in Discretix’s family of cryptographic
engines are symmetric ciphers, asymmetric ciphers, Hash and
random number generators.
DxDES - General Description
The DxDES cryptographic engine fully supports the DES and Triple DES algorithms.
The engine supports Electronic
Code Book (ECB) and Cipher Block Chaining (CBC) modes.
DxDES has
three interfaces: configuration (CPU) Data-In and Data-Out.
The CPU interface is a synchronous slave bus, which allows
an external processor to access the engine’s configuration
registers. The Data-In and Data-Out interfaces are FIFO-type
interfaces, which are used to stream in cipher/plain data to
be processed, and stream out plain/cipher output data. AMBA
AHB interfaces for Data-In and Data-Out are also available.
