Data Co-Processor (DCP) Overview
engine. Each channel also supports a high-priority mode that allows it to have priority over
the remaining channels. If multiple channels are selected as high-priority, the channel arbiter
selects among the high-priority channels in a round-robin fashion.
The data flow through the DCP module can be configured in one of five fashions, depending
on the functionality activated by the control packet:

• Memcopy/Blit Mode Data is moved unchanged from one memory buffer to another.
• Encryption Only Data from source buffer is encrypted/decrypted into the destination
• Hashing Only Data from source buffer is read, and a hash is generated.
• Encryption and Input Hashing Data from source buffer is encrypted/decrypted into
• Encryption and Output Hashing Data from source buffer is encrypted/decrypted
