Abstract:
In a virtual machine system (VMS) capable of concurrently running at least one operating system (OS) under one real computer system and a control program (VMCP) for controlling the VMS, the object is to reduce the overhead produced for simulating VM I/Os by direct I/O execution. A VM information area of a real sub-channel control block has a status field in which a flag indicating that the sub-channel is dedicated or not is contained. When the flag is "1", it means that the sub-channel is dedicated to the VM and the sub-channel scheduling by the VMCP is not necessary. As a real interruption priority order is dedicated to a VM, only I/O interruption requests of the VM are queued into the real interruption request queue of that dedicated priority order, and the mixing of VMs in that real interruption priority order is avoided. When an interruption control mask of an interruption priority order of the OS on the VM is "0" indicating that the interruption is not acceptable by the VM, the interruption conrol mask of the corresponding dedicated real interruption priority order is also "0" and the hardware interruption does not take place. Accordingly, the interruption is retained by the hardware and the I/O interruption retention for the VM by the VMCP is avoided.
Abstract:
An image data processing apparatus comprises output means for outputting image data for each pixel and compression means for compressing the image data supplied from the output means to image data of a predetermined number of bits. The compression means compresses the image data in accordance with a dot pattern having a predetermined number of tone levels.

Abstract:
The X-ray equipment related to the embodiment is configured from a plurality of pressure rising units, a switching unit, and a switching control unit. The plurality of pressure rising units are connected to the battery unit and generate direct current voltage. The switching unit switches over the plurality of pressure rising units and supplies direct current voltage to the X-ray generating unit. The switching control unit transmits switching instructions to the switching unit for switching over the pressure rising unit after receiving voltage supply instructions with respect to the X-ray generating unit until said voltage supply instructions terminate. The switching control unit controls discharging of the condenser inside the pressure rising unit switched over by the switching instructions and the control of commencing charging of the condenser inside the pressure rising unit following termination of discharging.
Abstract:
In a storage system, when a recovered error occurred upon access to a storage apparatus, a data redundancy determination unit determines whether data to be accessed has redundancy. When the data is determined to have no redundancy, an anomaly-occurring portion determination unit determines that the storage apparatus is not an anomaly-occurring portion and at the same time, an error history determination unit determines whether a recovered error occurred at the time of the past access to the storage apparatus other than that of the access destination. The anomaly-occurring portion determination unit determines whether a common transmission path is the anomaly-occurring portion based on the determination result of the error history determination unit.

Abstract:
A microelectronic assembly may include a substrate containing a dielectric element having first and second opposed surfaces. The dielectric element may include a first dielectric layer adjacent the first surface, and a second dielectric layer disposed between the first dielectric layer and the second surface. A Young's modulus of the first dielectric layer may be at least 50% greater than the Young's modulus of the second dielectric layer, which is less than two gigapascal (GPa). A conductive structure may extend through the first and second dielectric layers and electrically connect substrate contacts at the first surface with terminals at the second surface. The substrate contacts may be joined with contacts of a microelectronic element through conductive masses, and a rigid underfill may be between the microelectronic element and the first surface. The terminals may be usable to bond the microelectronic assembly to contacts of a component external to the microelectronic assembly.

The vias electrically connect the substrate contacts respectively to the conductive elements, and the substrate contacts are joined respectively to the contacts of the microelectronic element. The vias, compliant layer and substrate contacts are adapted to appreciably relieve stress at the substrate contacts associated with differential thermal contact and expansion of the assembly.
Abstract:
A processing unit performs a method including controlling a reading-out of data from a first storage medium at a predetermined read-out data rate to produce inputted data, and controlling a compression of the inputted data to produce first compressed data of a first compressed format. The method includes controlling a storage of the first compressed data in a second storage medium at a faster writing data rate than the predetermined read-out data rate, controlling a reading-out of second compressed data of a second compressed format from the second storage medium, and controlling a decompression of the second compressed data to produce decompressed data. The method also includes controlling simultaneously the storage of the first compressed data in the second storage medium, the reading-out of the second compressed data from the second storage medium, and audibly reproducing the decompressed data. The first compressed format is different from the second compressed format.
