摘要： Circuits, systems, and methods relating to processor which processes a plurality of sequentially arranged instructions. In the method, one method step (10) receives into a processor pipeline an instruction from the plurality of sequentially arranged instructions. Another step (12) determines whether the received instruction comprises a short forward branch instruction. If the received instruction comprises a short forward branch instruction, the method (14) issues a detection signal and (16) issues a condition signal representing whether or not the condition of the short forward branch instruction is satisfied. Continuing, the method (18) receives into the processor pipeline a first group of instructions of the plurality of sequentially arranged instructions, where each is between the short forward branch instruction and the target instruction. Each such instruction passes fully through the processor pipeline and the method (26) suppresses its result in response to the detection signal if the condition signal represents that the condition of the short forward branch is satisfied.

摘要： A computer system (8) comprising a central processing unit (12) and a memory hierarchy. The memory hierarchy comprises a first cache memory (16) and a second cache memory (26). The first cache memory is operable to store non-pixel-information, wherein the non-pixel information is accessible for processing by the central processing unit.

摘要： A multiple cycle memory access unit issues a memory access load or store, delaying a predetermined number of instruction cycles between it activation and its initial data transfer. The multiple cycle memory access unit controls a predetermined plural number of accesses and operates independently and in parallel with the instruction flow of the data processor. The multiple cycle memory access unit delays a predetermined number of instruction cycles between sequential data transfers of the predetermined number of data transfers. This predetermined period may be the same as the initial delay or it may be determined independent of the initial delay. The operation of the multiple cycle memory access unit is subject to predication on an instruction specified data registers. The multiple cycle memory access unit preferably provides predetermined register number cycling among the plural data registers. The multiple cycle memory access unit preferably aborts operation, stops and saves its internal state on a predetermined event.

摘要： A host module (2) including a host CPU (10) and a configurable expansion bus controller (28, 28', 128) is disclosed. The expansion bus controller (28, 28', 128) is configurable by way of configuration signals (BCFG) to be operable in various bus configurations for communicating signals between a module bus (IBUS) and external buses (XPCI1, XPCI0). These modes include combining the external buses (XPCI1, XPCI0) into a single bus of the 64-bit PCI type, operating the external buses (XPCI1, XPCI0) as separate 32-bit PCI buses, as separate CardBus buses, as separate AGP buses (either at one or multiple data transfers per cycle), or as combinations thereof. Certain of the configuration signals (BCFG) are used to select the clock frequencies at which the external buses (XPCI1, XPCI0) operate, in either of the 64-bit or 32-bit PCI protocols, or in the AGP bus protocol when present. The external buses (XPCI1, XPCI0) may be operable at different speeds, and at different protocols, depending upon the state of the configuration signals (BCFG).

摘要： An active integrated circuit socket includes plural pin sockets receiving corresponding pins of an integrated circuit and plural socket pins making electrical contact with a printed circuit board. At least one active electronic component requiring electrical power for operation connects a pin sockets to a corresponding socket pin. The active electronic component may be a single ended input to differential output driver, a differential input to single ended output driver, a single ended to differential input/output transceiver or a voltage level shifter. These active components may include passive termination resistors. The single ended to differential transceiver may further include an enable input determining the direction of data transmission. This invention may be employed as an electronic system upgrade product including at least two active integrated circuit sockets connected via a flexible sheet including a plurality of electrical conductors connecting differential signal lines. The flexible sheet may dispose a grounded conductor between each pair of differential signal conductors. The differential signals on the printed circuit board or the flexible sheet enabled by this invention are better able to support high speed data transfer than the single ended signals at the pins of the integrated circuits.

摘要： A microprocessor-based system (2) is disclosed, based on an x86-architecture microprocessor (5). The system includes a memory address space (30) and a input/output address space (40), where input/output operations are performed in an I/O mapped manner. According to a first embodiment of the invention, burstable access is performed to areas of the main memory (32) which are blocked from cache access, by the microprocessor (5) asserting the cache request signal (CACHE#) in combination with the control signal (M/IO#) indicating that an I/O operation is requested. The memory controller (10) interprets this combination as a burst request to the non-cacheable memory location (32), indicates the grant of burst access by asserting the cache acknowledge control signal (KEN#), and the burst memory access is then effected. According to a second embodiment of the invention, burst access to non-cacheable memory space (32) is acknowledged by the memory controller (60) by way of a burst acknowledge signal (BEN#) that is separate from the cache acknowledgment signal (KEN#).

摘要： In a preferred method embodiment, the method operates a microprocessor (36). The method fetches (14) a short backward branch loop (34) of instructions, wherein the short backward branch loop comprises a branch instruction (SSB) and a target instruction (TR) The method also determines that the short backward branch instruction is a short backward branch instruction after fetching it. Still further, the method stores (30) a short backward branch loop of execution unit instructions. This short backward branch loop comprises a branch execution unit instruction (SSB) and a target execution unit instruction (TR). Additionally, without re-fetching the short backward branch loop after the storing step, the method also executes (22) a plurality of iterations of the short backward branch loop of execution unit instructions over a plurality of clock cycles. More specifically, for certain ones the plurality of clock cycles (clock cycle 10), the execution step executes both a first set of the execution unit instructions corresponding to a first iteration and a second set of the execution unit instructions corresponding to a second iteration, where the second iteration immediately follows the first iteration.
