摘要： An array of processing elements can incorporate a degree of redundancy. Specifically, the array includes one or more spare, or redundant, rows of array elements, in addition to the number required to implement the intended function or functions of the device. If a defect occurs in one of the processors in the device, then the entire row which includes that defective processor is not used, and is replaced by a spare row.
摘要翻译：一系列处理元件可以并入一定程度的冗余。具体而言，除了实现设备的预期功能或功能所需的数量之外，该阵列还包括一个或多个备用或冗余的数组元素行。如果设备中的一个处理器中出现缺陷，则不使用包含该缺陷处理器的整个行，并由备用行替换。

摘要： Data is transmitted from a sending processor over a network to one or more receiving processor in a forward direction during an allocated slot, and acknowledge signals are sent in a reverse direction during the same allocated slot, to indicate whether the receiving processor is able to receive data. If one or more of the receiving processors indicates that it is unable to receive the data, the data is retransmitted during the next allocated slot. This means that the sending processor is able to determine within the slot period whether a retransmission is necessary, but that the slot period only needs to be long enough for one-way communication.
摘要翻译：在所分配的时隙期间，数据从发送处理器通过网络传送到一个或多个接收处理器，并且在相同的分配时隙期间以相反的方向发送确认信号，以指示接收处理器是否能够接收数据。如果一个或多个接收处理器指示它不能接收数据，则在下一个分配的时隙期间重传该数据。这意味着发送处理器能够在时隙周期内确定是否需要重传，但是时隙周期只需要足够长以进行单向通信。

摘要翻译：在所分配的时隙期间，数据通过网络从发送处理器以正向方向发送到一个或多个接收处理器，并且在相同的分配时隙期间以相反的方向发送确认信号，以指示接收处理器是否能够接收数据。如果一个或多个接收处理器指示它不能接收数据，则在下一个分配的时隙期间重传该数据。这意味着发送处理器能够在时隙周期内确定是否需要重传，但是时隙周期仅需要足够长以进行单向通信。

摘要： Processes are automatically allocated to processors in a processor array, and corresponding communications resources are assigned at compile time, using information provided by the programmer. The processing tasks in the array are therefore allocated in such a way that the resources required to communicate data between the different processors are guaranteed.

摘要： There is described a processor architecture, comprising: a plurality of first bus pairs, each first bus pair including a respective first bus running in a first direction (for example, left to right) and a respective second bus running in a second direction opposite to the first direction (for example right to left); a plurality of second bus pairs,each second bus pair including a respective third bus running in a third direction (for example downwards) and a respective fourth bus running in a fourth direction opposite to the third direction (for example upwards), the third and fourth buses intersecting the first and second buses; a plurality of switch matrices, each switch matrix located at an intersection of a first and a second pair of buses; a plurality of elements arranged in an array, each element being arranged to receive data from a respective first or second bus, and transfer data to a respective first or second bus. The elements in the array include processing elements, for operating on received data, and memory elements, for storing received data. The described architecture has the advantage that it requires relatively little memory, and the memory requirements can be met by local memory elements in the array.

摘要： There is described a processor architecture having a plurality of processing elements, each element having at least one input port and at least one output port, each port having at least a data bus and a valid data signal line; and a bus structure which contains a plurality of switches which are arranged so as to allow an output port of any first processing element to be connected to the input port of any second processing element for a time interval, in which each processing element is enabled to set a value on the valid data signal line of its output port to a first logic state when the associated data bus contains a transfer value, and to a second logic state when the data bus does not contain a transfer value, and in which each processing element is further enabled to enter a waiting state for a predetermined time interval when the value on the valid data signal line of the associated input port is in the second logic state. This reduces the power consumption of the device.
