DSP96002 STANDARD DSP BENCHMARKS
 
Program size and instruction cycle counts for the DSP56000/1 are in  parentheses on the line following the
DSP96002 program size and  instruction cycle count.  
All floating-point data ALU operations are performed using single  precision operations (".s" extension on
opcode) rather than in extended  precision (".x" extension on opcode).  Using only single precision will  yield
the same exact answers on any other machine using IEEE standard  single precision assuming the same
operations are used and performed in  the same sequence.  Using a mixture of extended precision and sin-
gle  precision may produce higher precision results at the expense of not  obtaining exact IEEE conform-
ance.
