If we are talking about a PC which uses x86 hardware (Intel, AMD etc), yes with the Gigahertz speed, using software will be faster than using hw accelerator, in this case FPGA but the original question was I believe usage in an embedded environment and using ARM processor. Now using a hw accelerator should make sense - right ? ________________________________________ From: owner-openssl-us...@openssl.org [owner-openssl-us...@openssl.org] On Behalf Of John R Pierce [pie...@hogranch.com] Sent: Thursday, March 11, 2010 9:26 AM To: openssl-users@openssl.org Subject: Re: CPU usage and FPGA support
