With the increasing amount of PC-based embedded systems on the gaming market, embedded hardware and embedded software represent an important economical factor. From this point of view it is necessary to protect the system from unlicensed copying or distribution. Another aspect is the need to protect the embedded systems from unauthorized development and reverse engineering in terms of quality assurance.

A hacker can attack in several ways but most likely focuses on the embedded security device. Depending on the demanded level of security and the costs restraints, several methods exist for fulfilling the following requirements:

- Programmable

- Read protection of the content

- Implementation of algorithms

- Implementation of additional functions (e.g. watchdog, sensor interface, boot-up logic)

- Copy management / prevention

In general all these requirements are met by low cost single chip microcontrollers or programmable logic devices (FPGA, CPLD) 

The PMIO-3400BS is a PCI card to provide the Battery backup SRAM, EEPROM, TPM and FPGA security features for PC-base gaming platform; it's easy to incorporate with the main board by plugging in PMIO-3400BS, there is ready driver in Windows XP, XP embedded, and Linux OS system with example programs to access the NVRAM, EEPROM and TPM easier.
