Figure 2 : Hardware Configuration of the TOE
Controller Board
The Controller Board is a device that contains Processors, RAM, NVRAM, Ic Key, and FlashROM. The
Controller Board sends and receives information to and from the units and devices that constitute the MFP,
and this information is used to control the MFP. The information to control the MFP is processed by the
MFP Control Software on the Controller Board. The following describes the components of the Controller
Board:
- Processor
A semiconductor chip that performs basic arithmetic processing for MFP operations.
- RAM
A volatile memory medium which is used as a working area for image processing such as
compressing/decompressing the image data. It can also be used to temporarily read and write
internal information.
- NVRAM
A non-volatile memory medium in which TSF data for configuring MFP operations is stored.
- Ic Key
A security chip that has the functions of random number generation, cryptographic key generation
