Message-ID: <[email protected]> Date: Tue, 17 Feb 2009 15:16:56 -0500 From: Paul Creekmore <[email protected]> To: [email protected] Subject: [Patch-gnuradio] USRP 1 CIC Decimator Removal Patch Here is a patch to correct a bug in the USRP 1 FGPA code. As written, the code will not build if RX_CIC_ON is not defined (if the user attempts to build a version without the CIC decimator), the compiler directives include a block of code fails to correctly rout the data and sample strobe directly to the halfband filter. ---Side note--- Incidentally, I've tested the USRP with this patch applied, both the CIC filter and halfband filter removed, and my quantization code (previously presented for review on the discussion list) in place and successfully achieved a 64 MHz sample rate for low quantization levels. "Low" is defined by the quality of the USB connection and any host computer processing/hard drive speed limitations. --Paul

This patch was integrated into developer branch pcreekmore/quantization in r10680. It is now pending merge into the trunk as part of integrating the additional quantization options implemented in this branch.
