Initially DOS (DR-DOS 3.3) was written for the Intel 8088/8086, a uniprocessor system. So following Flynn's taxonomy it was a SISD (single instruction stream, single data stream) computer architecture.

 

But with the introduction of the MMX extention on the X86 architecture, it was no longer a SISD, but a SIMD ( (single instruction stream, multiple data stream) computer architecture.
 

But I don't know if DR-DOS was modified to use the multiple data stream. 

For my la
And last one for what kind of hardware is written DR-DOS 7.03 and explain.
I already know that DR-DOS was basically written for a SISD (single instruction stream, single data stream) computer architecture (8088/8086) But the Pentium MMX and later where able to do SIMD (single instruction stream, multiple data stream) but I don't know if DR-DOS 7.03 did use this possibility.
