Functional Description 17
cPCI-6530
shared, each logical processor has its own architectural state with
its own set of general-purpose registers and control registers. This
feature must be enabled using the BIOS and requires operating
system support. Intel recommends enabling Hyper-Threading
Technology with Microsoft Windows 7, Vista, and XP, and dis-
abling Hyper-Threading Technology using the BIOS for all previ-
ous versions of Windows operating systems.
3.6 Trusted Platform Module
The cPCI-6530 integrates an Atmel AT97SC3204 Trusted Plat-
form Module (TPM). The TPM is a secure controller with added
cryptographic functionality to provide users a secure environment
in e-commerce transactions and Internet communications.
The key features Trusted Platform Module (TPM) offers are:
X Fully compliant to the Trusted Computing Group (TCG)
Trusted Platform Module (TPM) version 1.2 specification
X Hardware hash accelerator for SHA-1 algorithm
X Advanced Crypto Engine (ACE) for asymmetric key opera-
tions(up to 2048-bit key length) to make hardware protec-
tion.
X Tick counter to extend the time required to decipher the key
X In addition to encryption key created by user. it also provide
some security features to protect the integrated circuit itself:
X Over/Under-voltage detection to monitor the system stabil-
ity. If the voltage fluctuates dramatically, this function can
block the data transfer and lock the chip.
X Low/High frequency sensor to detect the IC clock fre-
quency. If the frequency fluctuates dramatically, this func-
tion can block the data transfer and lock the chip.
X Reset filter to filter reset signal in order to break the time set
by tick counter is received
X Memory encryption to protect memory
X Physical shield in the IC to protect the die from intruding or
hacking by matching the data transferred on the 2 layer
metal shield on the IC. If the data is not matched, the IC
may be blocked.
