RISC microprocessor offers fast encryption and communication processing

10 September 2003 DSP, Micros & Memory

Renesas Technology Europe has released a 32-bit RISC microprocessor which features a IPsec accelerator for fast encryption and communication processing. The SH7710 device also offers two on-chip Ethernet controllers that enable connection to two Ethernet LANs. Both peripherals make it suitable for security enabled devices designed for use in networks, such as VPN dedicated boxes, home gateway servers, surveillance cameras and IP phones.

The SH7710 is based on the company's SuperH RISC SH3-DSP CPU core that operates at speeds of up to 200 MHz and achieves a high processing capability of 260 MIPS. The on-chip DSP supports various kinds of middleware, such as a voice CODEC and echo canceller, and enables fast execution of multimedia related processing such as VoIP.

The IPsec accelerator implements security in the IP or network layer and supports DES and 3DES encryption/decryption methods and MD5 and SHA-1 authentication methods. In addition to the encryption circuitry, buffer memory and dedicated data transfer DMACs are provided, allowing data transfer directly between external memory and the buffer memory, and between the buffer memory and encryption circuitry, without CPU intervention, reducing CPU load.

The on-chip Ethernet controllers support 10/100 Mbit/s Ethernet. The SH7710 also features a FIFO-equipped serial interface that can be connected directly to a serial CODEC.
