Abstract: In executing an EEPROM emulation by a flash memory incorporated in a semiconductor device, there is a problem that the data holding period of the flash memory is shorter than the EEPROM. The flash memory manages data by block unit. Therefore, it is required to securely perform a block change before the specification of the data holding period of the flash memory passes.

When data level becomes below the data level check voltage, the block change is performed.

Abstract: A personality layer running above an operating system kernel puts any threads that the personality layer is responsible for into new states which the kernel does not know about. This prevents the kernel from performing operations on a thread which has been placed in one of these new states where these operations are sensitive to state of the thread itself (such as kill, suspend, change priority). Instead, the kernel redirects these thread operations to a handler in the personality layer which then handles the operation. The kernel is thus, in essence, extensible through the use of the added personality layers, and it can therefore be used to run legacy real-time applications written for other real-time operating systems.

When the new binary value is outputted, the binary value stored in the buffer is deleted, and the new binary value is stored in the buffer.

Abstract: A computing system in which a software component executing on a platform can reliably and efficiently obtain state information about a component supported by the platform through the use of a shared memory page. State information may be supplied by the platform, but any state translation information needed to map the state information as supplied to a format as used may be provided through the shared page. In a virtualized environment, the state translation information can be used to map the value of a virtual timer counter or other component from a value provided by a virtual processor to a normalized reference time that will yield the same result, regardless of whether the software component is migrated to or from another virtual processor. Use of a shared page avoids the inefficiency of an intercept into a virtualized environment or a system calls in native mode operation.
