    摘要: A built-in memory is divided into the following two types: first memories 5 and 7 and second memories 4 and 6, and made accessible in parallel by third buses XAB and XDB and second buses YAB and YDB respectively. Thereby, a CPU core 2 can simultaneously transfer two data values from the built-in memory to a DSP engine 3. Moreover, the third buses XAB and XDB and the second buses YAB and YDB are also separate from first buses IAB and IDB to be externally interfaced and the CPU core 2 can access an external memory in parallel with the access to the second memories 4 and 6 and the first memories 5 and 7.

    摘要: Herein disclosed is a semiconductor integrated circuit capable of executing processing operations using two-dimensional data in a high parallelism and at a high speed.
    The semiconductor integrated circuit comprises: a two-dimensional memory array (MAR); a parallel data transfer circuit (TRC) for transferring the data read out in parallel through data lines, in parallel to a processing circuit group by selecting the word lines of the two-dimensional memory array; and the processing circuit group (PE) for executing processing operations in parallel by using the data transferred from said parallel data transfer circuit. Each of the processing circuits can make access to the plurality of series word lines of said two-dimensional memory array and the data lines through the parallel data transfer circuit, and the data lines of the two-dimensional memory array, to which a plurality of adjoining processing circuits can make access, have an overlapped range.
    Since the data lines of the two-dimensional memory array, to which the adjoining processing circuits can make access, have an overlapped range, the convolution processing operations or the like can be ex ecuted in parallel for the two-dimensional data stored in the two-dimensional memory array.
