Subsystem
Internal RAM, shared with VPU.
The on-chip memory controller (OCRAM) module, is an interface between
the system’s AXI bus, to the internal (on-chip) SRAM memory module. It is
used for controlling the 128 KB multimedia RAM, through a 64-bit AXI bus.
Supports secure and regular boot modes.
The ROM controller supports ROM patching.
Protecting read only data from modification is one of the basic elements in
trusted platforms. The run-time integrity checker, version 3 (RTIC) block is
a data-monitoring device responsible for ensuring that the memory content
is not corrupted during program execution. The RTIC mechanism
periodically checks the integrity of code or data sections during normal OS
run-time execution without interfering with normal operation. The purpose
of the RTIC is to ensure the integrity of the peripheral memory contents,
protect against unauthorized external memory elements replacement and
assist with boot authentication.
SAHARA (symmetric/asymmetric hashing and random accelerator),
version 4, is a security coprocessor. It implements symmetric encryption
algorithms, (AES, DES, 3DES, RC4 and C2), public key algorithms (RSA
and ECC), hashing algorithms (MD5, SHA-1, SHA-224 and SHA-256), and
a hardware true random number generator. It has a slave IP Bus interface
for the host to write configuration and command information, and to read
status information. It also has a DMA controller, with an AHB bus interface,
to reduce the burden on the host to move the required data to and from
memory.
SATA HDD interface, includes the SATA controller and the PHY. It is a
complete mixed-signal IP solution for SATA HDD connectivity.
The security controller is a security assurance hardware module designed
to safely hold sensitive data, such as encryption keys, digital right
management (DRM) keys, passwords and biometrics reference data. The
SCCv2 monitors the system’s alert signal to determine if the data paths to
and from it are secure, that is, it cannot be accessed from outside of the
defined security perimeter. If not, it erases all sensitive data on its internal
RAM. The SCCv2 also features a key encryption module (KEM) that allows
non-volatile (external memory) storage of any sensitive data that is
temporarily not in use. The KEM utilizes a device-specific hidden secret key
and a symmetric cryptographic algorithm to transform the sensitive data
into encrypted data.
