Security Engine (SEC) 2.1
12.4.4.13 MDEU FIFOs
MDEU uses an input FIFO to hold data to be hashed. The input FIFO is multiple-addressable, but those
multiple addresses point only to the write (push) end of the FIFO. A write to anywhere in the MDEU FIFO
address space causes the 64-bit-words to be pushed onto the MDEU input FIFO, and a read from anywhere
in the MDEU FIFO address space returns all zeros.
12.4.5
This section contains details about the random number generator (RNG), including modes of operation,
status and control registers, and FIFOs.
The RNG is an execution unit capable of generating 64-bit random numbers. It is designed to comply with
the FIPS-140 standard for randomness and non-determinism. A linear feedback shift register (LSFR) and
cellular automata shift register (CASR) are operated in parallel to generate pseudo-random data.
The RNG consists of six major functional blocks:
The states of the LFSR and CASR are advanced at unknown frequencies determined by the two ring
oscillator clocks and the clock control. When a read is performed, the oscillator clocks are halted and a
collection of bits from the LFSR and CASR are XORed together to obtain the 64-bit random output.
Most of the registers described here would not normally be accessed by the host. They are documented
here mainly for debug purposes. In typical operation, the MDEU is used through channel-controlled
access, which means that most reads and writes of MDEU registers are directed by the SEC channels.
Driver software performs host-controlled register accesses on only a few registers for initial configuration
and error handling.

SHA-1 and SHA-256 are big endian. MD5 is little endian. The MDEU
module internally reverses the endianness of the key upon writing to or
reading from the MDEU key registers if the MDEU mode register indicates
MD5 is the hash of choice.
