摘要： A method of processing data contained in data packets comprises storing a set of microcode instructions of which some are test instructions prescribing a respective test between a data pattern in a packet and a test pattern; defining by means of bit masks a respective multiplicity of programs each consisting a group of instructions selected from the said set of instructions; providing a particular one of said bit masks; reading out from storage the selected group of instructions in the program defined by said particular one of said bit masks, said selected group including at least one of said test instructions; and executing the instructions in the selected group on data packets. Matches between data patterns in said packets and a test pattern defined by said at least one test instruction may be detected. The invention preferably includes reading buffer data and applying to data packets appearing sequentially in the data a selected group of said instructions which independently test data of the data packets in turn.

摘要： Embodiments of a system and method are disclosed that can include a memory unit, and a memory management unit coupled to the memory unit. The memory management unit can include address mapping circuitry and access control circuitry operable to: provide address mappings for at least a frame stack and a link stack in the memory unit for programs being executed by the processing unit, and provide an access permission indicator applicable to any segment of the memory unit. A processing unit can save context information for a program to the frame stack, and execute a savelink instruction subsequent to the execution of a branch and link instruction. If the access permission indicator is set, the savelink instruction saves to the link stack a return address provided by the branch and link instruction.

摘要： A search mechanism improves the performance of a queue system including a queue for storing a plurality of data items and search mechanism by maintaining a key cache data structure having an array of entries, each of which have a key field and a pointer field. The key and pointer fields respectively of each cache entry are used for storing a key value of a different one of the enqueued data items of the queue and a pointer to that enqueued item. The key of each data item to be enqueued is used to generate an index value for accessing a location of the key cache array to obtain immediate access to the corresponding enqueued data item thereby reducing the search time for determining the proper point within the queue for inserting the data item to be added.

摘要： The present invention provides a highly glycosylated iduronate-2-sulfatase enzyme comprising an iduronate-2-sulfatase polypeptide with at least 5 kilodalton (kDa) more sugar than iduronate-2-sulfatase purified from a natural source, e.g. human liver. The present invention also provides an enzymatically active polypeptide fragment or variant of such a highly glycosylated iduronate-2-sulfatase. The present invention further provides an isolated nucleic acid encoding iduronate-2-sulfatase, as well as an expression vector, a host cell and a method for producing the present highly glycosylated iduronate-2-sulfatase enzyme. In one embodiment the present invention is directed to a method for producing a glycosylated iduronate-2-sulfatase enzyme which comprises culturing a host cell containing a nucleic acid encoding an enzymatically active iduronate-2-sulfatase polypeptide wherein the host cell glycosylates the polypeptide to a greater degree than a native iduronate-2-sulfatase polypeptide expressed by a natural human liver cell.

摘要： The individual rows of a ROM array are accessed by a row decoder/driver in response to the arrival of the address of the individual row on the address lines. A plurality of programmable switches store the address of a row of ROM array found to contain one or more defects. If the incoming address is that of the defective row each of a plurality of comparators connected to both an address line and the associated switch outputs a coincidence signal to an AND gate. The output of the AND gate accesses a spare row of RAM which thus replaces the defective row of the ROM array. Access to the spare row is automatic upon receipt of the address of the defective row. Each column of the ROM array contains a check bit computed from the remaining contents of the respective column, and the data to be stored in the spare row is generated from the remaining contents of the ROM array. At initialization, the generated data which should have been stored in the defective row is written into the spare row.

摘要： A method and information processing system with improved cache organization is provided. Each register capable of accessing memory has associated metadata, which contains the tag, way, and line for a corresponding cache entry, along with a valid bit, allowing a memory access which hits a location in the cache to go directly to the cache's data array, avoiding the need to look up the address in the cache's tag array. When a cache line is evicted, any metadata referring to the line is marked as invalid. By reducing the number of tag lookups performed to access data in a cache's data array, the power that would otherwise be consumed by performing tag lookups is saved, thereby reducing power consumption of the information processing system, and the cache area needed to implement a cache having a desired level of performance may be reduced.

摘要： A cache management system employs a replacement policy in a manner that manages redundant accesses to cache elements. The cache management system comprises a cache, a replacement policy state storage and an update control module. The update control module comprises a buffer for storing recent addresses, a comparison unit for comparing a new address with those stored in the recent address buffer, and an update unit which determines whether to update the replacement policy state storage. When an address matches those stored in the recent address buffer, a replacement status update is suppressed.

摘要： Carboxylic acids produced by carbonylation and having iodide and oxidisable impurities are purified by contacting with hydrogen peroxide and recovering the purified acid by distillation or evaporation. Preferably a strong acid such as sulphuric acid is used as a catalyst. Product contamination by sulphur from sulphuric acid and by excess peroxide may be reduced by the use of metal salts in the recovery step.
