USB Host Core

The USB Host Core manages the connected USB devices and provides a framework for the USB Class Drivers. The USB Host Core contains a Hub Driver, which monitors the hub ports for device attach, or detach events.

When a new USB device is attached, the Hub Driver enumerates the device and invokes the appropriate USB Class Driver. When the device is detached, it performs the necessary steps to remove the device.

Onchip USB Host can handle multiple hubs and devices simultaneously and supports hot plugging of hubs and devices.

USB Host Controller Driver

The USB Host Controller Driver communicates with the controller hardware to transfer data across the USB bus. Onchip USB Host provides drivers for full-speed OHCI and the high-speed EHCI interfaces.

Onchip Bluetooth Stack is a Bluetooth SIG certified host software component specifically designed for resource constrained embedded systems. It supports both BLE and BR/EDR in dual mode as well as single mode configurations. The stack is compatible with Bluetooth 4.1 specification.



  • Supports HCI based Bluetooth controllers.
  •  Well documented and programmer-friendly API
  •  Supports HCI,GAP L2CAP, RFCOMM, SDP, OBEX, AVDTP Protocols
  •  Supports BLE GAP and GATT profiles.
  •  Supports SPP, HFP, PBAP,A2DP, AVRCP profiles.
  •  Provides API framework for developing new profiles quickly.
  •  Compatible with any 32-bit CPU with ANSI C compiler.
  •  OS abstraction layer supports any OS or standalone without OS.


Onchip Bluetooth Stack architecture and design strictly conforms to the Bluetooth V4.1 specifications. The following diagram shows the supported layers within the Bluetooth stack. All layers are configurable by the user.


Onchip Bluetooth Stack provides framework to develop new profiles very easily. It currently supports profiles including Serial Port Profile (SPP), Hands-free Profile (HFP) Phonebook Access Profile (PBAP), Advanced Audio Distribution Profile (A2DP) and Audio/Video Remote Control Profile (AVRCP). Onchip will add new profiles based on the request and when the specifications are released by Bluetooth SIG.

Bluetooth Core

The Bluetooth core contains the following higher layers of the stack.
HCI Driver
HCI Transport Driver
RFCOMM – is a transport protocol based on L2CAP. It emulates RS-232 serial ports. The RFCOMM protocol supports up to 60 simultaneous connections between two BT devices. RFCOMM provides data stream interface for higher level applications and profiles.
SDP – (Service Discovery Protocol) provides a means for applications to discover which services are available and to determine the characteristics of those available services. SDP uses an existing L2CAP connection. Further connection to Bluetooth devices can be established using information obtained via SDP.
L2CAP – (Logical Link Control and Adaptation Protocol) provides connection-oriented and connectionless data services to upper layer protocols with data packet size up to 64 KB in length. L2CAP performs the segmentation and reassemble of I/O packets from the baseband controller.
HCI Generic Driver – This driver implements the HCI Interface standardized by Bluetooth SIG. It establishes the communication between the Stack and the HCI Firmware in the Bluetooth hardware. It communicates with the Bluetooth controller hardware via the HCI transport layer driver.
HCI Transport Driver – The Bluetooth controllers are connected to the host using interface like UART, USB, SDIO, etc. The HCI Transport Layer Driver provides hardware abstraction to the rest of the Bluetooth stack software. This driver makes it possible to use Bluetooth stack with different hardware interfaces. Currently UART and USB interfaces are supported. The SDIO support will be available in future releases.


The Onchip File System is compact and highly reliable embedded FAT16/FAT32 file system that has been specifically designed for embedded applications requiring data storage to media such as SD/MMC, USB and Flash drives.


Functional Overview

  • Compact & full featured embedded File System
  • Supports RAM, NAND, NOR, SD, MMC and USB Mass storage devices
  • Microsoft DOS/Windows compatible FAT16/32 file system

  • Easily integrated with virtually any FLASH or physical media device.

File System Architecture

The Onchip File System architecture (shown above) is designed in a modular fashion that allows it to support multiple different storage I/O devices, and has been optimized for resource constrained devices.

FAT16/FAT32 File System

The File System layer implements the FAT16/FAT32 protocol. This layer translates the file operations to block I/O requests and forwards it to the corresponding Storage I/O Device driver. This layer also manages dynamic attachment/removal of storage devices.

File System API

The File System API layer provides two interfaces to the applications. One is a POSIX interface that provides standard file API functions such as fopen(), fread(), fwrite() and fclose() etc., The second is a Native interface that provides non-standard API for operations like directory management and file system management.

Storage Media Driver

The Storage Media Driver is a hardware dependent driver for the file system software stack. It provides low level I/O functions allowing the rest of file system to access the storage devices for accessing NAND/NOR/SD/MMC and RAM Disk devices.

Additionally the File System can be used with our USB Host and Mass Storage Class to support most kinds of USB devices.
