Processing unit for processing neural network, electronic device including the same, and host processor

An electronic device comprising:

• a first processing unit configured to receive a producing kernel command corresponding to a producing kernel and execute the producing kernel based on the producing kernel command, the producing kernel configured to produce data;
• and
• a second processing unit configured to receive a consuming kernel command corresponding to a consuming kernel and execute the consuming kernel based on the consuming kernel command, the consuming kernel referring to the data,
• wherein the first processing unit is further configured to generate a first additional command that requests that an identifier, corresponding to the producing kernel command, be written to a first register of the first processing unit, and
• the second processing unit is further configured to generate a second additional command that requests a wait until an identifier, corresponding to the consuming kernel command, is written to a second register of the second processing unit.

A host processor comprising:

• a user mode driver configured to drive a host program and to generate a kernel command configured to enable executing kernels for neural network processing;
• and
• a kernel mode driver configured to manage resources of a processing unit configured to execute the kernels,
• wherein one of the user mode driver and the kernel mode driver includes a command injector configured to generate a different additional command according to a type of the kernel command, enabling referencing between the kernels, and to output the kernel command and the additional command corresponding to the kernel command.
