 Name:         »Dsp_IOStream« - Data transfer from and to DSP via two 
               interrupts

 Opcode:       101

 Syntax:       void Dsp_IOStream( int8_t *data_in, int8_t *data_out, 
               int32_t block_insize, int32_t block_outsize, int32_t 
               num_blocks, int32_t *blocks_done );

 Description:  The function sends and receives simultaneously via DSP 
               interrupt handling num_blocks data blocks with a size 
               of block_insize or block_outsize DSP-words from/to the 
               DSP. The sent data is taken from the buffer data_in, 
               the received data is stored in the buffer data_out. For 
               each interrupt one block is sent and one received 
               (except for the first and last interrupt). At the same 
               time the counter blocks_done, which keeps track of the 
               number of blocks transferred, will be incremented. As 
               the data is transferred via an interrupt, the function 
               does not have to wait. Via blocks_done the program can 
               then determine whether the transfer has been completed.

 Return value: The function does not return a result.

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

 Group:        DSP programming
