Subject: [PATCH v1 04/33] baseband/acc100: add LDPC encoder padding function
Date: Mon, 15 Aug 2022 22:52:29 -0700 [thread overview]
Message-ID: <20220816055258.107564-5-hernan.vargas@intel.com> (raw)
In-Reply-To: <20220816055258.107564-1-hernan.vargas@intel.com>
LDPC Encoder input may need to be padded to avoid small beat for ACC100.
