The present invention is particularly directed to an information processing device (10) substantially comprising a vector processing unit (VPU) and an in-memory computing unit (IMC unit). The VPU (14) has a vector register designed to store vector components. The IMC unit (15) has a crossbar array structure adapted to store values (referred to as weights). The IMC unit is connected to a vector register (148) of the VPU. The information processing apparatus is configured to perform a number of operations including a vector transfer operation, a vector feed operation, and a vector read-out operation. In operation, a vector transfer operation causes a vector component of an input vector to be stored in a vector register of the VPU. When corresponding instructions are received from a main processing unit (12) to which the VPU is connected, these components are typically fetched from neighboring memories (11). A vector feed operation feeds an input vector component as an input from a vector register to an IMC unit. This in turn causes the IMC unit to perform a matrix-vector multiplication based on the weight and the input vector component to obtain an output vector accordingly. Finally, the vector readout operation writes an output vector component of the output vector to the vector register. Starting from this time, the output vector component may be transferred to a memory or a main processing unit (for further processing), or further processed in the VPU prior to being transferred to the memory or the main processing unit. The invention also relates to related systems and methods.
