Hardware computing system with software mediation and method of operation thereof

A method of operation of a hardware computing system comprising:

• transferring a software application through a peripheral controller to a memory device;
• generating a command stream by a general purpose central processing unit including retrieving the command stream from the software application;
• and
• receiving, by an application manager, the command stream for executing a command by a programmable execution engine and providing a status through a command execution interface to the general purpose central processing unit for the command from the command stream including storing a result in the memory device.

A hardware computing system comprising:

• a memory device having a software application loaded therein;
• a general purpose central processing unit coupled to the memory device for generating a command stream by reading a command of the software application;
• and
• an application manager, having a programmable execution engine, coupled to the memory device and the general purpose central processing unit includes the programmable execution engine executes the command and a command execution interface provides status to the general purpose central processing unit for the command from the command stream.
