Average Cycle Count Sum of Decoder Routines, as a Function of n
errors
The assembly code for matrix multiplication contains the potential for one contention in one of the five cycles of
the inner loop, since the table
exp_2_bin_extended
is accessed twice in the same cycle. The probability per
contention is 1/16.
Table 2
and
Table 3
depict the results obtained for the ADSL application. The symbol time is
246.4
μ
sec. Assuming that the DSP runs at 300 MHz, the full processor load is 73,920 cycles. The results are
obtained in the worst case, in which both
T
and
n
errors
equal 8.
