Operating system (OS) independent peripheral control
An Operating-System (OS) independent peripheral API is provided to applications processing in an application OS. The API communicates with a peripheral OS that includes device drivers for peripherals. Requests for accessing the peripherals are made through the API of the application OS but access and control of the peripherals are maintained through the device drivers of the peripheral OS.
1. A method, comprising:
receiving, at a first Operating System (OS), a request for access to a peripheral interfaced to the first OS, wherein the request originated from a second OS, wherein receiving the request further includes receiving the request from the second OS as inter-communications between two separate Virtual Machines (VMs), wherein a first VM processes the first OS and a second VM processes the second OS;
translating the request into a peripheral driver format; and
providing the translated request to a peripheral driver for processing by the peripheral.
2. The method of claim 1 , wherein receiving further includes receiving the request from the second OS over a wired network connection.
3. The method of claim 1 , wherein receiving further includes receiving the request from the second OS over a wireless connection.
4. The method of claim 1 , wherein receiving further includes receiving the request from the second OS from an application that processes within the second OS.
5. The method of claim 4 , wherein receiving further includes ensuring the second OS has no direct access or control over the peripheral and wherein the second OS is not connected to the peripheral.
6. The method of claim 1 , wherein translating further includes converting the request from an OS-independent command into one or more driver-specific commands recognized by the peripheral driver.
7. The method of claim 1 further comprising, receiving results from the peripheral driver in a driver format.
8. The method of claim 7 further comprising, translating the results in the driver format to an OS-independent Application Programming Interface (API) format.
9. The method of claim 8 further comprising, providing the translated results to an API processing in the second OS.
10. A method, comprising:
providing an Application Programming Interface (API) to a first Operating System (OS);
receiving a peripheral request that originates from an application processing in the first OS and receiving the peripheral request through the API, wherein receiving further includes receiving the peripheral request through the API as an intra-device connection originating from a first Virtual Machine (VM) of a device that processes the first OS to a second VM of the device that processes the method;
translating the peripheral request into a peripheral driver command of a peripheral interfaced to a second OS; and
processing by a peripheral driver the peripheral driver command on the peripheral.
11. The method of claim 10 , wherein receiving further includes receiving the peripheral request though the API over wired network connection.
12. The method of claim 10 , wherein receiving further includes receiving the peripheral request through the API over a wireless network connection.
13. The method of claim 10 further comprising, translating results from the peripheral processing the peripheral driver command into an API format and communicating the results in the API format to the application processing in the first OS.
14. The method of claim 10 further comprising, processing the method on a physical computing core that is separate and different from a second physical computing core that executes the first OS.
15. The method of claim 10 further comprising, processing the method on a network-accessible gateway device that controls access to the peripheral independent of the first OS, wherein the first OS is not connected to and has no direct access to the peripheral.
16. A Self-Service Terminal (SST), comprising:
a first Operating System (OS) operable to execute an application for controlling the SST; and
a second OS operable to control a plurality of peripheral devices coupled to the SST and available for use by the application;
wherein the first OS is configured to: i) identify a request for a peripheral device originating from the application and ii) provide the request through an OS-independent Application Programming Interface (API) command to the second OS, and wherein the second OS is configured to: iii) translate the API command into a peripheral command and iv) process the peripheral command on the peripheral device
wherein the SST is an Automated Teller Machine (ATM).
17. The SST of claim 16 , wherein the peripheral device is connected to the second OS of the ATM and is one of:
a display, a touch screen, a currency dispenser, a card reader, a scanner, a speaker, a microphone, a keyboard, a Personal Identification Number (PIN) pad, a receipt printer, and a wireless transceiver for wireless communication between the ATM and a wireless-enabled device.
