A technique for implementing in a networked client-server environment, e.g., the Internet, network-distributed advertising in which advertisements are downloaded, from an advertising server to a browser executing at a client computer, in a manner transparent to a user situated at the browser, and subsequently displayed, by that browser and on an interstitial basis, in response to a click-stream generated by the user to move from one web page to the next. Specifically, an HTML advertising tag is embedded into a referring web page. This tag contains two components. One component effectively downloads, from an distribution web server and to an extent necessary, and then persistently instantiates an agent at the client browser. This agent “politely” and transparently downloads advertising files (media and where necessary player files), originating from an ad management system residing on a third-party advertising web server, for a given advertisement into browser cache and subsequently plays those media files through the browser on an interstitial basis and in response to a user click-stream. The other component is a reference, in terms of a web address, of the advertising management system. This latter reference totally “decouples” advertising content from a web page such that a web page, rather than embedding actual advertising content within the page itself, merely includes an advertising tag that refers, via a URL, to a specific ad management system rather than to a particular advertisement or its content. The ad management system selects the given advertisement that is to be downloaded, rather than having that selection or its content being embedded in the web content page.

Technique for implementing browser-initiated user-transparent network-distributed advertising and for interstitially displaying an advertisement, so distributed, through a web browser in response to a user click-stream

A method and apparatus for transferring data between two storage media, and is used in an illustrative embodiment to transfer data between two storage media in a shadow set, the storage media being accessible to one or more host processors. The method of the preferred embodiment includes the steps of: A. receiving a command from one of the host processors, the command specifying data to be transferred from a first storage medium to a second storage medium; B. transferring the data specified in the command received from the host from the first storage medium to the second storage medium in a series of subtransfers, each of the subtransfers transferring a portion of the data; and C. processing one or more I/O requests to the shadow set received from one or more host processors by, for each received I/O request: a. implementing the I/O request if the I/O request does not involve a section of the shadow set currently involved in one of the subtransfers; and b. stalling the I/O request if the I/O request involves a section of said shadow set currently involved in one of the subtransfers, and implementing the I/O request when the subtransfer has completed.

Transferring data in a digital data processing system

Disclosed are methods and apparatus, which enable the reconfigurable control of vehicles, homes, computers and other applications. Physical controls and virtual displayed controls on single and multipoint touch screens are used, separately or in combination to enable higher visibility and understanding of control information and easier operation of controls, particularly useful in stressful situations. Some embodiments use optical sensors and rear projection of displayed embodiments, and are advantageous where curved screens are desired such as in a car.

Control systems employing novel physical controls and touch screens

A peripheral device controller has an EEPROM which stores microinstructions to be placed in a random access memory control store. The EEPROM also stores peripheral configuration information. This information is obtained by polling the peripheral devices connected to the controller and storing the resulting information in the EEPROM. Upon powering up, the microinstructions stored in the EEPROM are transferred to the control store via execution of instructions held in a boot PROM. The controller, therefore, provides a fast control store while maintaining permanence of the microinstructions after power is extinguished. Means are also provided to update the control store and EEPROM. The EEPROM may upon CPU command be updated with new microinstructions held in main memory or obtained from peripheral devices.

In a data processing system wherein a plurality of functional units are interconnected by way of a common communication bus in an environment of high data transfer rates, a logic control system is provided for interjecting firmware control during a data transfer between a disk device and main memory to accommodate unsolicited bus requests without incurring data errors or compromising the data transfer rate. Data transferred between the disk device and a disk controller interfacing directly with the common bus is routed through a FIFO (first-in-first-out) buffer under hardware control. The buffer signals the absence of data in its input register and the presence of data in its output register. The signals are logically combined and ANDed with a firmware controlled logic gate to indicate the occurrence of data transfer states. During such transfer states, data is transferred under hardware control between the FIFO buffer and main memory. When the input register of the FIFO buffer is filled during a data transfer from main memory to the disk device, or when the FIFO buffer is empty during a transfer of data from the disk device to main memory, hardware controlled data transfers are not required. In that event the firmware control system is permitted to access the common bus to service unsolicited bus requests.

Synchronization control system for firmware access of high data rate transfer bus

A plurality of units which are coupled to transfer requests, transfer data over an asynchronous bus network during allocated bus transfer cycles. The network has a tie-breaking bus priority network which is distributed to a common interface portion of each of the plurality of units and grants bus cycles and resolves simultaneous requests on a priority basis. At least one unit includes bus saturation detection apparatus included within its common interface portion for monitoring bus activity over established intervals of time. The detection of the occurrence of at least one available cycle over the given interval of time signals that the bus network is not in a saturated state. When the indicator specifies that the bus network is saturated, the unit throttles down its operation by increasing the amount of time between issuing data requests. Throttling continues until the bus is no longer being saturated.

Method and apparatus for limiting the utilization of an asynchronous bus with distributed controlled access

A logic data control system including a first-in-first-out (FIFO) buffer predictor is provided for the transfer of data between a main memory unit and a peripheral control unit of a data processing system. Data from main memory is stored into the input registers of the peripheral unit, and thereafter loaded into an array of data FIFOs for transfer to a peripheral storage device. A predictor FIFO operates in parallel with the data FIFOs, and is loaded with a dummy or flag byte each time a data request is made to main memory. When a data word is loaded into the data FIFOs, the input register of the predictor FIFO is sensed. If the flag byte in the predictor FIFO has dropped from the input register into the FIFO stack, a request is issued to main memory for an additional data word. When the data FIFOs are filled, the predictor FIFO also is filled and cannot generate an additional data request until a data byte has been unloaded from the data FIFOs to a peripheral storage device. The input register to the predictor FIFO thereupon is emptied, and another data request may be made to main memory.

Fifo look-ahead system

A firmware/hardware method and system is provided for testing interface logic in a data processing system having a plurality of system units intercommunicating over a common electrical bus. Under firmware control, an incorrect parity is generated in a main memory address to be loaded into output registers of a system unit supplying information to the bus. A bus cycle request is issued by the system unit, and when the bus is made available the system unit acknowledges the memory address to initiate a transfer of data from the bus into the input registers of the system unit. Thereafter, the data in the output registers of the device may be compared with the data in the input registers to detect interface logic errors.
