 Name:         »Dsp_BlkWords« - Wordwise data transfer of an array of 
               WORDS to the DSP.

 Opcode:       123

 Syntax:       void Dsp_BlkWords( void *data_in, int32_t size_in, void 
               *data_out, int32_T size_out );

 Description:  The function copies size_in signed 16-bit words from 
               the buffer data_in to the DSP. The words are extended 
               to signed DSP-wordlength before transfer. After all 
               data has been transferred, the procedure waits until 
               the data has been processed. Then size_out 16-bit DSP- 
               words are copied back into the buffer data_out, 
               irrespective of how much data is actually present. If 
               no data is to be sent, one has to set size_in to zero. 
               The same applies for the receipt; in that case size_out 
               is assigned zero. size_in and size_out are limited to 
               64 kbyte. Data is only exchanged when the DSP process 
               is ready for this.

 Return value: The function does not return a result.

 Availability: The function is available only on computers with the 
               DSP-56001 signal processor.
