Calculation apparatus and method for accelerator chip accelerating deep neural network algorithm

The invention provides a calculation apparatus and method for an accelerator chip accelerating a deep neural network algorithm. The apparatus comprises a vector addition processor module, a vector function value calculator module and a vector multiplier-adder module, wherein the vector addition processor module performs vector addition or subtraction and/or vectorized operation of a pooling layer algorithm in the deep neural network algorithm; the vector function value calculator module performs vectorized operation of a nonlinear value in the deep neural network algorithm; the vector multiplier-adder module performs vector multiplication and addition operations; the three modules execute programmable instructions and interact to calculate a neuron value and a network output result of a neural network and a synaptic weight variation representing the effect intensity of input layer neurons to output layer neurons; and an intermediate value storage region is arranged in each of the three modules and a main memory is subjected to reading and writing operations. Therefore, the intermediate value reading and writing frequencies of the main memory can be reduced, the energy consumption of the accelerator chip can be reduced, and the problems of data missing and replacement in a data processing process can be avoided.

Semiconductor memory device

Easy and fast memory access with correcting defects is to be realized. In a spare memory in a semiconductor memory device, a redundant memory cell array that stores the number of correcting defects is provided. When a signal from the outside is received, the signal is switched to the redundant memory cell array, and the number of correcting defects is judged. Then, based on the result of the judgment, it is determined the judgment of a defective memory cell is continued or the judgment is finished to write data to a main memory cell. By providing the redundant memory cell array that stores the number of correcting defects, a state of correcting defects can be observed fast in such a manner.

Method and device for accessing survey point of cluster database

The invention discloses a method and a device for accessing a survey point of a cluster database, which are applied to a Treap tree established in memory. A node memory index block of the Treap comprises the survey point identification range and access times; the node access times are sequentially reduced according to a preset node searching sequence; and preset number index blocks read from a disk is saved in the memory according to the high-low sequence of the access times. The method comprises the following steps: receiving a survey point access request in a preset cycle; searching a target node from a tree according to the target survey point identification and a preset node searching sequence in the request; increasing the access times of the target node; searching whether an index block corresponding to the target node exists in the memory or not, and determining the location of the survey point corresponding to the target survey point identification in the index block if the index block exists; accessing the survey point according to the survey point location; regulating the position of the target node in the Treap tree after the preset cycle is finished to sequentially reduce the access times of each node according to the node searching sequence.
