Keywords:risc microprocessor? renesas technology? ipsec accelerator?

The SH7710 32-bit RISC microprocessor from Renesas Technology features an IPsec accelerator for fast encryption and communication processing, and offers two on-chip Ethernet controllers that enable connection to two Ethernet LANs.

Suitable for use in VPN boxes, home gateway servers, surveillance cameras and IP phones, the SH7710 is based on a SuperH RISC SH3-DSP CPU core that operates at speeds of up to 200MHz and achieves a processing capability of 260MIPS.

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 data generation methods. In addition to the encryption circuitry, buffer memory and dedicated data transfer DMACs are provided to allow data transfer directly between external memory and the buffer memory, and between the buffer memory and encryption circuitry, without CPU intervention.

With a FIFO-equipped serial interface, the product also includes a 6-channel general-purpose DMAC.
