A software container image that includes components dependent on a first computer instruction set architecture (ISA) is ported to enable a container to execute using the container image on a computer having a second ISA different from the first. Porting the container image entails replacing components of the container image not compatible with the second ISA with equivalent components compatible with the second ISA. The porting is performed, in some instances, dynamically as part of running a container with the container image on a computer implementing the second ISA.

ISA-ported container images

A method for responding to media conference deficiencies, the method includes: monitoring, by at least one receiver, a quality of media conference signals being received by at least one receiver during the media conference; sending, in response to the monitoring, to at least an end user transmitter that transmitted the media conference signals, a quality indication representative of a quality of the received media conference signals; recording inadequately received media conference signals that were inadequately received by a certain end user receiver and participating in an activity related to a transmission, to the certain end user receiver, of the inadequately received media conference signals or of a representation of the inadequately received media conference signals.

A cache control system is disclosed for use with data storage apparatus having a movably mounted storage element, such as a magnetic or optical disk and solid-state cache memory, in which the storage element is not at operating speed when data access has not occurred during a predetermined time period, comprising means arranged to access data stored on the storage element if a read or write request cannot be satisfied via access to the cache memory and a cache replacement mechanism for transferring data between the cache memory and the storage element to maintain consistency of data therebetween. The system is characterized in that the cache replacement mechanism performs data transfers between the cache memory and the storage element only while the storage element is at operating speed after a read or write request has given rise to an access to the storage element.

A system and method for automatically adjusting the rate at which recorded speech is played back as a typist manually transcribes the speech. The typing speed is measured and a speech playback rate determined based on the measured speed. The playback rate of the audio is then automatically increased or decreased as appropriate to match the typing speed.

System and method for adapting speech playback speed to typing speed

Disclosed is a programming aid for enabling a computer program in source code form to be viewed using a general purpose document browser, which browser is responsive to a defined set of control tags determining the appearance of a document thereon, the programming aid comprising: a parser for generating a symbol table from an input file in which the program is stored; means to derive control tag locations from the symbol table; and an output file generator for inserting control tags into the program at the derived locations to generate an output file which can be viewed using the general purpose document browser. In this way, the full power of available general purpose document browsers may be used in software development and maintenance to view programs in a convenient way. A tool is provided that automatically marks up a program with control tags so that users are free to use the document browser of their choice as a powerful program browser.

A data storage disk device for a RAID disk array is disclosed, comprising a rotatably mounted disk having a data storage surface; a first head for reading data from and writing data to the data storage surface; with a second head for reading data from the data storage surface; and control means for executing a write operation to a sector, said write operation including reading the contents of the sector via the second head for subsequent processing and writing new data to the sector via the first head, the first and second heads being arranged with respect to the data storage surface so that the new data can be written to the sector on the same revolution of the disk as the reading operation. The addition of a second head to the disk storage device improves performance of the disk device for RAID applications.

A cache control system and method for operating a computer system which is capable of executing cached and non-cached memory accesses. The cache control system includes a frequency value store for each of a number of memory lines for storing a frequency value indicative of the number of accesses made thereto; an instruction store for storing the index of the last memory line accessed by each of a number of instructions; and control logic which, each time the processor attempts to access a memory location not in the cache memory, tests the frequency value for the last memory line accessed by the current instruction and, if the number of accesses for the memory line exceeds a predetermined threshold, (a) fetches the memory line of the memory location from the main memory into the cache memory and executes a cached memory access, and if not (b) executes a non-cached memory access.

Audio data processing apparatus connectable to a telephone network, the apparatus comprising a device (50) to receive from the network and record an audio signal comprising a sequence of audio segments separated by audio delimiters, characterised by a device (90) for scanning the recorded signal (65) to detect the audio delimiters (80) and generate a data structure in which a set of predefined field identifiers are each linked to a corresponding one of the recorded audio segments.

Audio data processing

An instruction scheduler for a computer, capable of speculatively scheduling load instructions by moving certain categories of load instructions in an input instruction sequence from a source block of instructions to a target block of instructions to form an output instruction sequence, the instruction scheduler comprising: logic for selecting a data-independent load instruction as a candidate for rescheduling; logic for determining whether the base register that the load instruction makes use of and/or the contents thereof meets any one of a number of conditions; logic for moving the selected load instruction from the source block to the target block in response to determination that any one of the conditions is met.
