Onchip Speech Stack is a software component that allows developers to easily integrate Speech Recognition and Text to Speech into embedded applications. It is also available in the form of hardware module for easy integration into electronic devices.
The OT-USB offers USB Host stack, USB Device stack, and USB OTG stack that are built from the ground up for the embedded applications. These stacks are compact, reliable and scalable for small to complex applications.
The Onchip USB Host component enables developers to integrate USB host functionality easily into embedded products.
It supports USB devices such as USB Flash drives, USB Serial, USB Audio, HID and Vendor specific Devices. It takes responsibility of detecting insertion and removal of USB devices and provides an API for reading device descriptors information and managing the data transfers.
USB HOST Architecture
The Onchip USB Host Architecture design (shown above), conforms to USB v1.1 and v2.0 specifications. Its modular design allows easy adaptation to different USB host controllers.
Applications can access the USB Host directly by using the USB host API interface, or by the APIs exposed by class drivers.
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 Device Architecture
The USB Device Architecture design (shown above), conforms to the USB v1.1 and USB v2.0 specifications, Its modular design allows easy adaptation to different USB device controllers.
Applications can access the USB Device directly by using the USB device-programming interface, or by the APIs exposed by class drivers.
USB device supports a wide range of Class Drivers, the most commonly requested being Mass Storage, HID, Bulk, CDC and Audio.

Integration and Support
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.
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.
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.
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.
