PrCONNECT Pro is a TCP/IP protocol stack for embedded systems. It provides the BSD Socket Interface to enable effective utilization of software assets and human resources for POSIX software such as Linux. TCP/IP Stack provides a large number of protocols*, including protocols for security and routing. It delivers substantial functionality and performance not only on multimedia or portable digital devices, but also on higher-level, advanced network devices.
* Some protocols are available as options.
BSD socket interface
BSD socket is provided as the application interface. This makes it easy to reuse the network applications of POSIX software, including Linux. POSIX software engineer resources can also be used for application development.
Best-class performance in the industry
Optimized high-performance networking
Field-proven results in high-speed, multi-session video streaming products.
Checksum offloading support enables faster speeds at the hardware level.
Supports IP multicast function
Supports an IP multicast sending and receiving function, which enables the same data to be sent to multiple specified destinations at the same time. This is effective for distributing large-sized media data such as video or audio.
Adjustable memory size
PrCONNECT Pro has a function selection switch for adjusting the overall code size. If the DHCP client, DNS client, IP multicast, or AutoIP function is not needed, this function selection switch can be used to specify the unused function during system configuration so that the function module is not embedded. The code is adjusted to the minimum required size to prevent wasteful memory consumption.
Supports various platforms
componentizes source code dependent on the target system, such as the operating
system, CPU, or NIC (Network Interface Card), as environment-dependent parts.
In addition, TCP/IP Stack is coded in C language. As a result, PrCONNECT Pro has
excellent portability, making it easy to support various platforms. PrCONNECT Pro is configured to run on eT-Kernel as
standard. On eT-Kernel, it runs on various profiles such as eT-Kernel
MCE (Multi-Core Edition).
When eT-Kernel is
used, PrCONNECT Pro can be implemented either as a library or as a T-Kernel
subsystem. (Refer to T-Engine's
Software Architecture Configuration for more information about
subsystems.) Socket API is provided as the interface even when PrCONNECT Pro Stack is
implemented as a T-Kernel subsystem. When implemented as a T-Kernel subsystem,
PrCONNECT Pro can also be used from a loadable system program or process
application. Loadable drivers can be added dynamically to PrCONNECT Pro.
Various protocols provided as standard
PrCONNECT Pro implements the following protocols as standard.
- DHCP client / DNS client / FTP client / FTP server / TELNET server
- IPv4/ARP/ICMP/IGMP/AutoIP, etc.
Many available optional protocols
The functions needed for use in the application can be selected. Dual stack for IPv4/IPv6 is also available.

* These optional protocols are released as required. The product configuration may be changed. Please contact us for details such as the release date.
Sample drivers and sample applications
A device driver that supports the network controller used in the system must be created for PrCONNECT Pro. The following source code is included as standard as a sample for this device driver. In addition, sample source code for various applications are included as standard.
- Device driver for Ethernet
・RZ/A1 built-in Ethernet controller
・Zynq-7000 built-in Ethernet controller
・Cyclone V SoC built-in Ethernet controller
・i.MX6 built-in Ethernet controller
- FTP sample application (server/client)
- TELNET sample application (server)
In addition to the samples included as standard, a wide range of controllers with a successful record of operation are available. Please feel free to contact us for details.
- Motorola 5282c3
- Intel 8255x
- SMSC LAN91C111
