The media processor (12) incorporates an execution unit (100) that maintains substantially peak data through out of media data streams. The execution unit (100) includes a dynamically partionable multi-precision arithmetic unit (102), programmable switch (104) and programmable extended mathematical element (106). A high bandwidth external interface (124) supplies media data streams at substantially peak rates to a general purpose register file (110) and the execution unit. A memory management unit, and instruction and data cache/buffers (118, 120) are provided. The general purpose, programmable media processor (12) is disposed in a network fabric consisting of fiber optic cable, coaxial cable and twisted pair wires to transmit, process and receive single or unified media data streams.

    Abstract: The present invention provides a cross-bar circuit (100) that implements a switch (115) of a broadband processor. The cross-bar circuit (100) includes: a switch circuit (115) which includes 2m.2n:1 multiplexor circuits (202-204) where each of the 2n:1 multiplexor circuits (202-204) has a unique n-bit index input, one disable input, and a 2n-bit wide source input receives an n-bit index at the n-bit index input, a disable bit at the disable input, and the 2n-bit input source word at the 2n-bit wide source input, and decodes the n-bit index either to select and output as an output destination bit one bit from the 2n-bit input source word if the disable bit has a logic low value; a cache memory (110) that has 2m cache datapath inputs; and 2m cache index input; and a control circuit (105) that has a plurality of control inputs receives the partially decoded instruction information on the plurality of control inputs, provides a second set of the n-bit indexes for the switch circuit (115), and provides the disable bits for the switch circuit (115) where the control circuit (105) is logically coupled to the switch circuit (115) and to the cache memory (110).

    Abstract: A system for processing geometry which reduces the amount of memory spaces while improving the processing speed. The system delivers vertices in sequence to a vertex queue (70) so that data in the vertex queue is freed as it is delivered and only minimal intermediate results are stored. By this incremental evaluation, less memory space is needed. In another aspect of the invention the vertices are maintained in the proper sequence so that sorting operation can be eliminated. A sorted vertex queue (70) and an unsorted vertex list (72) are utilized so that resorting of the entire vertex list may be prevented. In addition, a compressed format (34) for storing geometry is utilized based on the fact that much information can be rederived from a sorted and reduced vertex queue.

    Abstract: Circuit logique BICMOS amélioré (70) utilisant une paire de transistors bipolaires (21, 22) à couplage par émetteurs pour comparer de manière différentielle un signal d'entrée (Vin) et un niveau de référence logique (VBIAS). Chaque transistor bipolaire est chargé de manière résistive par un réseau de transistors (26, 27) à semiconducteur à grille isolée par oxyde métallique à canal P (PMOS) couplés en parallèle. La grille d'au moins une des combinaisons parallèles de transistors est couplée à un signal de commande (VREF2) fournissant une résistance de charge variable. De préférence, le signal de commande est fourni par un réseau de retour (52, 53) servant à maintenir à une valeur constante l'excursion de tension constante dans le réseau, malgré les variations de température.

    Abstract: Transistor bipolaire possédant un émetteur (25), une base (31) et un collecteur (30). Il comprend une zone de base intrinsèque (33) à zones latérales étroites (p-) et à zone centrale plus large (37). Les zones latérales sont contiguës à la zone dopée (31), et la zone centrale (37) se trouve sous l'émetteur (25). Le profil de dopage latéral de la base est tel que les concentrations de dopage dans la zone dopée (31) et la zone centrale (37) sont relativement élevées par rapport à celles dans les zones latérales étroites (p-) de la base intrinsèque (33). L'association des zones latérales étroites (p-) au profil de dopage latéral de la base limite l'étendue de la zone de déplétion à l'intérieur de la base, ce qui assure une réduction de la tension de claquage du transistor sans entraîner une perte du gain en courant.
