摘要:
Information of a first type is determined at an integrated circuit die of a data processing device included an integrated circuit package. The integrated circuit package includes the first integrated circuit die and a second integrated circuit die. Information of a second type is determined at the integrated circuit die. The first and second type of information is transmitted from the integrated circuit die to another integrated circuit die using a time-divided multiplexed protocol by transmitting the first information during a first time slot of the protocol and transmitting the second information during a second time slot of the protocol.
摘要:
In one embodiment, a node comprises a plurality of processor cores and a node controller configured to receive a first read operation addressing a first register. The node controller is configured to return a first value in response to the first read operation, dependent on which processor core transmitted the first read operation. In another embodiment, the node comprises the processor cores and the node controller. The node controller comprises a queue shared by the processor cores. The processor cores are configured to transmit communications at a maximum rate of one every N clock cycles, where N is an integer equal to a number of the processor cores. In still another embodiment, a node comprises the processor cores and a plurality of fuses shared by the processor cores. In some embodiments, the node components are integrated onto a single integrated circuit chip (e.g. a chip multiprocessor).

摘要:
A starvation avoidance mechanism for an input/output node of a computer system. A scheduler unit includes a first buffer circuit and a second buffer circuit. The first buffer circuit includes a first plurality of buffers for storing selected control commands received from a first source and the second buffer circuit includes a second plurality of buffers for storing selected control commands received from a second source. The scheduler further includes an arbitration circuit coupled to the first buffer circuit and to the second buffer circuit. The arbitration circuit may be configured to arbitrate between the control commands stored in the first buffer circuit and the control commands stored in the second buffer circuit. The outcome of selected arbitration cycles may be dependent upon a number of times in which a control command from a given one of the buffers is blocked due to an unavailable destination.

A virtual channel buffer bypass in a computer system input/output node. A control unit of an input/output node for a computer system includes a buffer circuit configured to receive control commands. The buffer circuit may include a plurality of buffers each corresponding to a respective virtual channel of a plurality of virtual channels for storing selected control commands that belong to the respective virtual channel. The buffer circuit may also be configured to determine whether each of the plurality of buffers is empty prior to storing a particular control command corresponding to a given one of the plurality of buffers. In addition, the buffer circuit may be configured to cause the particular control command to bypass the given one of the plurality of buffers in response to determining that each of the plurality of buffers is empty.
摘要:
A method and apparatus for combined transaction reordering and buffer management. The apparatus may include a buffer, a first generator circuit and a second generator circuit. The buffer is configured to store memory transaction responses received from a memory controller in a plurality of addressable locations. The first generator circuit is configured to generate a first memory transaction request encoded with a first tag corresponding to an address in the buffer in response to receiving a first memory request. The second generator circuit is configured to generate a second tag using the size of said first memory request added to the first tag. The first generator circuit may be further configured to generate a second memory transaction request encoded with the second tag corresponding to a second address in the buffer in response to receiving a second memory request successive to the first memory request. The second generator circuit may be further configured to generate a third tag using the size of the second memory request added to said second tag.
