Subject: [PATCH v1 2/4] common/ml: add data type conversion routines
Date: Thu, 8 Dec 2022 11:35:30 -0800 [thread overview]
Message-ID: <20221208193532.16718-3-syalavarthi@marvell.com> (raw)
In-Reply-To: <20221208193532.16718-1-syalavarthi@marvell.com>
Type conversion routines transform data from higher to lower
precision data types or vice-versa. These conversion functions
can be used by the ML driver implementations for quantization
and de-quantization.
Added driver routines for type conversion. These driver routines
invoke the architecture specific functions.
