  • Publication number: 20030078037
    Abstract: Subscriber units and base stations of telecommunication systems are equipped with RF to IF (EXA) circuit boards which provide complete flexibility for radio communication. The boards may communicate on any air interface standard (CDMA, TDMA, Bluetooth, 3G cellular, etc.) at any frequency or band of frequencies. Separate, independent forward and reverse channels may be assignment, each having its own air interface and frequency band. When a call is initiated, a set of optimum forward and reverse channels are assigned, taking into account relevant factors such as traffic, subscriber requirements for high speed data, etc., so that the channel assignment is tailored to the current communication needs. Channel assignment is updated as needs change, as other channels become available and at handoff. In a business model, air time on multiple telecommunication systems is sold to subscribers who can use this technology to roam widely.

  • Publication number: 20020099850
    Abstract: Resource requests made by clients of origin servers in a network are intercepted by reflector mechanisms and selectively reflected to other servers called repeaters. The reflectors select a best repeater from a set of possible repeaters and redirect the client to the selected best repeater. The client then makes the request of the selected best repeater. The resource is possibly rewritten to replace at least some of the resource identifiers contained therein with modified resource identifiers designating the repeater instead of the origin server.

  • Patent number: 4803619
    Abstract: Apparatus in a digital computer system capable of performing a call operation and a return operation for obtaining addresses of data from names representing the data. Each name is permanently associated with a procedure containing instructions to which the digital computer system responds. Each name further corresponds to a name table entry which is permanently associated with the same procedure. The corresponding name table entry for a name specifies how a base address and a displacement are to be derived using a plurality of current base addresses. The values of these addresses change only when the computer system executes a call operation suspending a current execution of a procedure and commencing another current execution or a return operation terminating the current execution and resuming the execution which was suspended to commence the terminated execution. The operation of resolving a name, i.e.

  • Patent number: 4675810
    Abstract: A digital computer system having a memory system organized into procedure and data objects, each having a unique identifier code and an access control list, for storing items of information and a processor for processing data in response to instructions. The instructions contain operation codes and names representing data. Each name corresponds to a name table entry in a name table which contains information from which the processor determines the location and the format for the data. The name table entry specifies a base address of one of a set thereof which change value only when a call or a return instruction is executed. A name interpretation system fetches a name table entry, calculates the base address and a displacement using the name table entry and the current architectural base address and adds the base address to the displacement to form the address of the data represented by the name.

  • Patent number: 4516203
    Abstract: Apparatus in a digital computer system for encaching data stored in the computer system's memory in a cache internal to the computer system's processor. The processor executes procedures (sequences of instructions). Data processed during an execution of a procedure is represented by operands associated with the procedure. Certain of the operands designate encacheable data items associated with each execution of the procedure. The values of the encacheable data items do not change for the duration of the execution. The operands designating encacheable data do so by means of codes specifying the designated encacheable items. The processor includes a cache for storing the encacheable items. The cache responds to a code specifying an encacheable item by outputting the value of the encacheable item specified by the code. The processor further includes cache loading apparatus for loading the encacheable items into the cache.

  • Patent number: 4514800
    Abstract: A digital computer system including a memory and a processor. The memory operates in response to memory commands received from the processor. Items of data stored in the memory include instructions to which the processor responds. Each instruction contains an operation code which belongs to one of several sets of operation codes. The meaning of a given operation code is determined by the operation code set to which the instruction belongs. Some of the instructions also contain names representing items of data used in the operation specified by the operation code. The processor includes an operation code decoding system which decodes the operation code as required for the instruction set to which it belongs, a name resolution system for deriving the address of the data item represented by a name from the name using an architectural base address contained in the name resolution system, and a control system which controls the operation of the processor.

  • Patent number: 4498131
    Abstract: A digital data processing system has a memory organized into objects containing at least operands and instructions. Each object is identified by a unique and permanent identifier code which identifies the data processing system and the object. The system utilizes unique addressing mechanisms the addresses of which have object fields, offset fields and length fields for specifying the location and the total number of bits of an addressed object. The system uses a protection technique to prevent unauthorized access to objects by users who are identified by a subject number which identifies the user, a process of the system for executing the user's procedure, and the type of operation of the system to be performed by the user's procedure. An access control list for each object includes an access control list entry for each subject having access rights to the object and means for confirming that a particular active subject has access rights to a particular object before permitting access to the object.

  • Patent number: 4493027
    Abstract: A method for executing call and return instructions in a digital computer system operating under control of microcode. The microcode may specify calls to and returns from sequences of microinstructions. A call microinstruction sequence corresponds to the call instruction. The call microcode in turn calls other microinstruction sequences for deriving pointers representing the location of the called procedure and of arguments from operands in the call instruction. As the call microcode obtains each argument pointer, it places the pointer on the stack. After it has obtained all of the argument pointers, it passes the pointer to the called procedure and a pointer to the argument pointers to a general call microinstruction sequence. That microinstruction sequence locates the called procedure, makes a new frame including the argument pointers, and saves the state necessary to resume execution of the call microinstruction sequence itself.
