Publication number: 20210159643Abstract: An electrical connector for high speed signals. The connector has multiple conductive elements that may serve as signal or ground conductors. A member formed with lossy material and conductive compliant members may be inserted in the connector. The conductive compliant members may be aligned with conductive elements of the connector configured as ground conductors. For a connector configured to carry differential signals, the ground conductors may separate pairs of signal conductors. The member may further include a conductive web, embedded within the lossy material, that interconnects the conductive compliant members. For a receptacle connector, the conductive elements may have mating contact portions aligned along opposing surfaces of a cavity. The conductive elements may have contact tails for attachment to a printed circuit board and intermediate portions connecting the mating contact portions and the contact tails. The conductive compliant members may press against the intermediate portions.Type: ApplicationFiled: February 1, 2021Publication date: May 27, 2021Applicant: Amphenol CorporationInventors: Brian Kirk, Jason Si, Ba Pham, Sam Kocsis, David Chan, Wonder Wang, Bob Tang, Martin Li, Smith Wu

Patent number: 7570646Abstract: A slave interface unit controls the exchange of data between a master processing unit and a plurality of slave processing units operating in the asynchronous transfer mode (ATM) of operation. The ATM slave interface unit has a receive unit and a transmit unit that exchange data cells and control signals with the ATM master processing unit. The receive unit and the transmit unit are coupled to a receive buffer storage unit and a transmit buffer storage unit, respectively. The receive buffer storage unit and the transmit buffer storage unit exchange data and control signals with the direct memory access unit. The ATM slave interface unit includes a configuration interface unit having a register that identifies the location in the data cell where the destination address is located and relates the destination address to the particular processing unit or memory location. The receive buffer unit uses the information in the register to determine the destination of the data cell.Type: GrantFiled: September 26, 2001Date of Patent: August 4, 2009Assignee: Texas Instruments IncorporatedInventors: Martin Li, Jay B.

Publication number: 20060268714Abstract: The management of flows can be simplified by only keeping unique flow information for locally important flows, and aggregating all other flows together. A flow control table of 16 entries, 15 unique and 1 aggregate is usually sufficient, particularly in systems where the traffic flows are relatively static. This greatly reduces the required logic for Xoff/Xon counters and timeout monitors Rather than every packet source checking each packet it sends, the flows needed by each unit are registered in the flow table and the table logic indicates to each unit whether it has any blocked flows.Type: ApplicationFiled: May 15, 2006Publication date: November 30, 2006Inventors: Andre Szczepanek, Martin Li, Steven Marshall, Travis Scheckel

Publication number: 20060256876Abstract: This invention enables many interrupt source bits spread among multiple interrupt registers. An interrupt status decode register reduces the number of read cycles required to decode the interrupt source. Each unique interrupt source has a predefined and fixed logical mapping to each bit of the decode register. The logical mapping is flexible per application. The decode register bit is set if the interrupt source is asserted and the interrupt source is mapped to that particular physical interrupt. Since each physical interrupt has an associated decode register, the ability to orthogonally arrange the sources and reduce the number of register reads is even greater.Type: ApplicationFiled: May 15, 2006Publication date: November 16, 2006Inventors: Andre Szczepanek, Martin Li, Steven Marshall, Travis Scheckel

Publication number: 20060256879Abstract: High speed networking systems such as PCI-Express and Serial Rapid I/O are based on the exchange of packets across switched networks of high speed serial links. Information in the headers of these packets indicate the kind of transaction they represent. Queuing all received packets in a single queue will cause interactions between transaction types. Indirection can be used create the effect of multiple independent queues from a shared memory. This provides efficient centralized packet storage, while allowing independent processing of different transactions types.Type: ApplicationFiled: May 15, 2006Publication date: November 16, 2006Inventors: Andre Szczepanek, Martin Li, Steven Marshall, Travis Scheckel

Publication number: 20060256878Abstract: A packet transmission system based on a simple linear linked list of packet descriptors is difficult to implement with modern switch based system because transmission acknowledgments may occur out of order in relation to packet transmission. The problem lies in how packet completion is indicated to the CPU to enable for efficient packet processing. A scoreboard system is scalable to support multiple single-segment messages and multiple multi-segment messages for hundreds of packets. When a message/segment has been sent out, the context information for the packet is remembered and its key is indexed into a CAM. When segment/message response comes back, a simple hardware lookup is performed, and the associated context information is retrieved.Type: ApplicationFiled: May 15, 2006Publication date: November 16, 2006Inventors: Andre Szczepanek, Martin Li, Steven Marshall, Travis Scheckel

Publication number: 20060256877Abstract: The Rapid I/O Messaging Logical Layer relies on the receiving device to map the incoming messages into specific memory locations. This uses software programmable mapping registers. The settings are compared to the header fields of the incoming Rapid I/O messages to determine if there is a match, in which case, the packet is mapped to a queue. Accessibility to a queue through the mapping register can be limited to discrete MAILBOX/LETTER combinations, or multiple combinations based on the masking bits. Long messages may be processed through a hardware lookup table implemented to break up transactions into Rapid I/O compliant packets.Type: ApplicationFiled: May 15, 2006Publication date: November 16, 2006Inventors: Andre Szczepanek, Martin Li, Steven Marshall, Travis Scheckel
