Abstract

Systems and corresponding methods include a system having an operating system based wholly around a protocol stack, such as a Transmission Control Protocol/Internet Protocol (TCP/IP) stack. The system may include a central processing unit (CPU) including the operating system embedded therein, and a network interface coupled with a network and the CPU. The network may be the Internet. The operating system is fundamentally a state machine. The kernel of the operating system is fundamentally just a protocol stack for communicating with one or more devices of the network via the network interface. The protocol stack may be a TCP/IP protocol stack, UDP/IP stack or combinations thereof. A chip may be provided that includes the TCP/IP stack state machine-based operating system embedded in a CPU. The resultant chip may be ultra low power, miniscule in size, and IP-centric.

Claims

1. A method comprising:

receiving, by an operating system embedded within and executing within a central processing unit (CPU), input/output (I/O) requests, the operating system comprising an operating system kernel based on a network protocol stack for processing the I/O requests according to at least one network protocol, wherein processing of all I/O requests utilizes a sockets style application programming interface (API), and wherein the network protocol stack comprises a Transmission Control Protocol/Internet Protocol (TCP/IP) stack such that the operating system consists of a TCP/IP stack state machine.

2. The method of claim 1, wherein processing the I/O requests comprises communicating data via a network interface, the network interface comprising one of an Ethernet controller and a wireless interface.

3. The method of claim 1, wherein executable instructions for the operating system are stored in memory of the CPU and executed through the sockets style application programming interface (API).

4. The method of claim 3, further comprising accessing via the sockets style API one or more of a keyboard input device and a display output device.

5. A computing system comprising:

a central processing unit (CPU) comprising an operating system (OS) embedded therein, the operating system comprising an operating system kernel based on a network protocol stack that processes I/O requests according to at least one network protocol, wherein processing of all I/O requests utilizes a sockets style application programming interface (API), and wherein the network protocol stack comprises a Transmission Control Protocol/Internet Protocol (TCP/IP) stack such that the operating system consists of a TCP/IP stack state machine.

6. The computing system of claim 5, further comprising a network interface that further comprises one of an Ethernet controller and a wireless interface.

7. The computing system of claim 5, wherein executable instructions for the operating system are embedded within the CPU and execute through the sockets style application programming interface (API).

8. The computing system of claim 5, wherein executable instructions for the operating system are stored solely in read only memory (ROM).

9. The computing system of claim 5, further comprising an asynchronous clock to serve as an internal clock for the operating system.

10. The computing system of claim 9, wherein the asynchronous clock is configurable to automatically stop when clock cycles are not needed.

11. The computing system of claim 5, wherein a time reference for the operating system kernel is based on a Simple Network Time Protocol (SNTP) from a remote time server coupled to a network, which is communicatively coupled with the computing system.

12. The computing system of claim 11, wherein the network further comprises the Internet.

13. The computing system of claim 5, wherein instructions for the operating system, executable by the central processing unit and stored in read only memory, are written in assembly language.

14. A chip comprising:

a central processing unit (CPU); and

an operating system embedded in the CPU, the operating system comprising an operating system kernel based on a network protocol stack for processing input/output (I/O) requests, wherein processing of all I/O requests utilizes a sockets style application programming interface (API), and wherein the network protocol stack comprises a Transmission Control Protocol/Internet Protocol (TCP/IP) stack such that the operating system consists of a TCP/IP stack state machine.

15. The chip of claim 14, wherein executable instructions for the operating system are stored solely in and execute solely from read only memory (ROM) and execute through the sockets style application programming interface (API).

16. The chip of claim 14, further comprising an asynchronous clock to serve as an internal clock for the operating system kernel.

17. A non-transitory computer-readable storage media having embodied thereon an operating system, the operating system executable by a processor to handle input/output (I/O) requests, the operating system consisting of:

an operating system kernel that consists of;

a sockets layer, a transmission control protocol (TCP) layer, an Internet Protocol (IP) layer, and a driver layer, the operating system kernel handling I/O requests between at least one application and at least one hardware resource of a computing device;

wherein processing of all I/O requests utilizes a sockets style application programming interface (API).

18. The storage media of claim 17, wherein the non-transitory computer-readable storage media comprises a ROM of a computing device.

19. The storage media of claim 17, wherein the at least one application is executed on an additional computing device that is located remotely from the computing device that comprises the at least one hardware resource.

20. The storage media of claim 17, wherein the operating system kernel binds the at least one hardware resource to an open socket of the sockets layer.
