The cross-network bridge includes a bus interface for connecting to a system bus, and bridging circuitry configured to translate between (i) system-bus transactions that are exchanged between one or more local devices and one or more remote processors among the processors, the one or more local devices being coupled to the system bus and served by the system bus, and the one or more remote processors being located across a network from the cross-network bridge, and (ii) data units that convey the system-bus transactions, for transmitting and receiving as network packets over the network to and from the remote processors.

Abstract: A decompression apparatus includes a cache memory and a decoder. The decoder is to receive a compressed input data stream including literals and matches. Each literal represents a data value, and each match represents a respective sequence of literals by a respective offset pointing to a respective past occurrence of the sequence of literals. The decoder is to decompress the input data stream by replacing each match with the corresponding past occurrence, so as to produce an output data stream. In replacing a given match with the corresponding past occurrence, the decoder is to (i) when the offset indicates that the past occurrence is cached in the cache memory, retrieve the past occurrence from the cache memory, and (ii) when the offset indicates that the past occurrence is not contained in the cache memory, fetch the past occurrence from an external memory.

Abstract: A peripheral device includes two or more peripheral-bus modules, a coherent interconnect, and two or more tunnel adapters coupled between the peripheral-bus modules and the coherent interconnect. The peripheral-bus modules are to exchange peripheral-bus packets with one another in accordance with a peripheral-bus protocol. The coherent interconnect is to connect electronic components of the peripheral device in accordance with a coherent interconnect protocol. The tunnel adapters are to convey the peripheral-bus packets between the peripheral-bus modules over the coherent interconnect, by translating between the peripheral-bus packets and messages of the coherent interconnect protocol.

Abstract: A method and system are provided for limiting unnecessary data traffic on the data busses connecting the various levels of system memory. Some embodiments may include processing an invalidation command associated with a system or network operation requiring temporary storage of data in a local memory area. The invalidation command may comprise a memory location indicator capable of identifying the physical addresses of the associated data in the local memory area. Some embodiments may preclude the data associated with the system or network operation from being written to a main memory by invalidating the memory locations holding the temporary data once the system or network operation has finished utilizing the local memory area.

Abstract: A device includes a receiver including a timestamp generator to update timestamps at a first rate. The receiver is to estimate a first time for receiving a signal, wherein the signal is associated with a synchronization operation. The receiver is further to receive the signal at a second time. The receiver is further to determine a difference between the second time and the first time, wherein the difference is associated with an error of the timestamp generator of the receiver. The receiver can also adjust the first rate to a second rate at which to update the timestamps by the timestamp generator, responsive to determining the difference between the first time and the second time.

Abstract: One or more blocks of dynamic random access memory are embedded together with a processor and a data bus on an integrated circuit. The data bus has a bandwidth b for general operation including memory access, the block of dynamic random access memory further requiring data refresh at a refresh rate r. The block thus forms an eDRAM on the integrated circuit, typically an ASIC. A refresh controller embedded with the eDRAM may control refresh by clocking the data bus at a rate higher than the rate of the data bus to accommodate both the required memory access and the required data refresh.
