Classification: CPC G | IPC G

Claim 1:
2. An integrated circuit device comprising:
a first neural network accelerator circuit having a first buffer memory and a first processing engine array, the first neural network accelerator circuit configured to perform neural network computations on a first batch of data with a set of weight values;
a second neural network accelerator circuit having a second buffer memory and a second processing engine array, the second neural network accelerator circuit configured to perform neural network computations on a second batch of data with the set of weight values; and
direct memory access circuitry configured to:
load the set of weight values from an external memory into the first buffer memory of the first neural network accelerator circuit; and
load the set of weight values that was stored in the external memory from the first buffer memory of the first neural network accelerator circuit into the second buffer memory of the second neural network accelerator circuit,

wherein the first buffer memory is configured to retain the set of weight values until the set of weight values has been loaded into the first processing engine array and loaded into the second buffer memory.
