8.11
Cryptographic co-processor (C3)
SPEAr BASIC has an hardware cryptographic co-processor with the following features:
●
Supported cryptographic algorithms:
–
Advanced encryption standard (AES) cipher in ECB, CBC, CTR modes.
–
Data encryption standard (DES) cipher in ECB and CBC modes.
–
SHA-1, HMAC-SHA-1, MD5, HMAC-MD5 digests.
●
Instruction driven DMA based programmable engine.
●
AHB master port for data access from/to system memory.
●
AHB slave port for co-processor register accesses and initial engine-setup.
●
The co-processor is fully autonomous (DMA input reading, cryptographic operation
execution, DMA output writing) after being set up by the host processor.
●
The co-processor executes programs written by the host in memory, it can execute an
unlimited list of programs.
●
The co-processor supports hardware chaining of cryptographic blocks for optimized
execution of data-flow requiring multiple algorithms processing over the same set of
data (for example encryption + hashing on the fly).
8.12
Low jitter PLL
Within the USB Hosts and device a local low jitter PLL is provided to meet the USB2.0
specification requirements.
8.13
Main PLL
Two PLLs are provided so that the external memory bus can run at a different frequency to
the internal AHB. To reduce the system emission both the PLL are offering four operational
modes:
●
Normal mode
●
Fractional mode
●
Double side dithering mode
●
Single side dithering mode
