“Execution unit” (EU) is the generic term for the functional blocks that perform cryptographic
computations. The EUs are compatible with many protocols, and can work together to perform high-level
cryptographic tasks. The SEC’s execution units are as follows:
The following sections give an overview of the EUs. Operational details of each EU are given in
Section 10.7, “Execution Units.”
10.1.4.1
The PKEU is capable of performing many advanced mathematical functions to support both RSA and ECC
public key cryptographic algorithms. ECC is supported in both F
modes.
To assist the host in performing its desired cryptographic functions, the PKEU supports functions with
various levels of complexity. For example, at the highest level, the accelerator performs modular
exponentiations to support RSA and performs point multiplies to support ECC. At a lower level, the PKEU
can perform simple operations such as modular adds and multiplies. For more information about the unit’s
operation, refer to
10.1.4.1.1
The PKEU has its own data and control units, including a general-purpose register file in the
programmable-size arithmetic unit. The field or modulus size can be programmed to any value between
33 bits and 1024 bits in programmable increments of 8, with each programmable value i supporting all
actual field sizes from 8i – 7 to 8i. The result is hardware supporting a wide range of cryptographic security.
Larger field / modulus sizes result in greater security but lower performance.

In host-controlled access (intended primarily for debug purposes), the host moves data in and out
of execution units directly through memory-mapped EU registers. No descriptor is involved.
