Publication number: 20230342325Abstract: A link controller includes a Peripheral Component Interconnect Express (PCIe) physical layer circuit for coupling to a communication link and providing a data path over the communication link, a first data link layer controller which operates according to a PCIe protocol, and a second data link layer controller which operates according to a non-PCIe protocol. A multiplexer-demultiplexer selectively connects both data link layer controllers to the PCIe physical layer circuit. A protocol translation circuit is coupled between the multiplexer-demultiplexer and the second data link layer controller, the protocol translation circuit receiving traffic data from the second data link layer controller in a non-PCIe format, encapsulating the non-PCIe format in a PCIe format, and passing traffic data to the multiplexer-demultiplexer circuit.Type: ApplicationFiled: June 30, 2023Publication date: October 26, 2023Applicants: ATI Technologies ULC, Advanced Micro Devices, Inc.Inventors: Gordon Caruk, Maurice B.

Patent number: 8856458Abstract: A single interconnect is provided between a first processor and a second processor, such that the first processor may access a common memory through the second processor while the second processor can be mostly powered off. The first processor accesses the memory through a memory controller using a standard dynamic random access memory (DRAM) bus protocol. Instead of the memory controller directly connecting to the memory, the access path is through the second processor to the memory. Additionally, a bidirectional communication protocol bus is mapped to the existing DRAM bus signals. When both the first processor and the second processor are active, the bus protocol between the processors switches from the DRAM protocol to the bidirectional communication protocol. This enables the necessary chip-to-chip transaction semantics without requiring the additional cost burden of a dedicated interface for the bidirectional communication protocol.Type: GrantFiled: December 15, 2009Date of Patent: October 7, 2014Assignee: Advanced Micro Devices, Inc.Inventors: Joseph D.

Patent number: 8775747Abstract: A method and system for performing byte-writes are described, where byte-writes involve writing only particular bytes of a multiple byte write operation. Embodiments include mask data that indicates which bytes are to be written in a byte-write operation. No dedicated mask pin(s) or dedicated mask line(s) are used. In one embodiment, the mask data is transmitted on data lines and store in response to a write_mask command. In one embodiment, the mask data is transmitted as part of the write command.Type: GrantFiled: March 19, 2013Date of Patent: July 8, 2014Assignee: ATI Technologies ULCInventors: Joseph D.

Publication number: 20120008671Abstract: A system includes a first communication device and a second communication device. The first communication device includes a programmable region. The programmable region of the first communication device is programmed so that an associated signal includes a number of preamble cycles. The second communication device also can include a programmable region. The programmable region of the second communication device can be programmed so that an associated signal includes a number of preamble cycles. The number of preamble cycles can be based on a variety of factors, such as the topology or implementation of the system. In an embodiment, the number of preamble cycles is associated with a data strobe signal, and data is not read or written in response to the data strobe signal until all of the preamble cycles have been transmitted and received.Type: ApplicationFiled: September 23, 2011Publication date: January 12, 2012Inventors: Joseph D.

Patent number: 7869525Abstract: A dynamic bus inversion (DBI) method and system are described. In various embodiments, a transmitter transmits data over a multi-bit high-speed bus to a receiver. In an embodiment, the transmitter determines whether to invert the bus based on the number of data bits that will be transitioning to a new value. If it is determined that the bus is to be inverted, the transmitter encodes a DBI signal on a shared line of the bus. In an embodiment, the shared line is used for different purposes at different times, obviating the need for a dedicated line or pin for the encoded DBI signal. The receiver receives and decodes the DBI signal and, in response, appropriately decodes the received data.Type: GrantFiled: February 17, 2006Date of Patent: January 11, 2011Assignee: ATI Technologies, Inc.Inventors: Joseph D.

Publication number: 20090251987Abstract: In one aspect, there is provided a method for controlling data output by a memory device. The method may include receiving a first clock signal having a first frequency. Moreover, a second and third clock signals may be produced from the first clock signal. The second and third clock signals may have second and third frequencies, respectively, that are about equal to the first frequency. The second and third frequencies may be out of phase relative to each other. A controller may output a first data in response to a rising edge of the second clock signal and output a second data in response to another rising edge of the third clock signal.Type: ApplicationFiled: June 15, 2009Publication date: October 8, 2009Applicant: ADVANCED MICRO DEVICES, INC.Inventor: Joseph D.
