Abstract
A built-in memory is divided into the following two types: first memories and and second memories and , and made accessible in parallel by third buses XAB and XDB and second buses YAB and YDB respectively. Thereby, a CPU core can simultaneously transfer two data values from the built-in memory to a DSP engine .
