From 68930e85b5945db8ffea055fd178bc1f88b31d99 Mon Sep 17 00:00:00 2001 From: Vadim Yanitskiy Date: Thu, 19 Jan 2017 03:33:24 +0700 Subject: tests/conv: separate test logic To be able to add some more tests, related to convolutional coding, without duplication of code, the test logic was separated from the conv_test.c into conv.c and conv.h.
