A Self-Reconfigurable Platform for the Implementation of 2D Filterbanks with Real and Complex-Valued Inputs, Outputs, and Filter Coefficients

Table 12

Performance comparison for different filterbanks and implementation types (dynamic and static). Frame sizes used: QCIF, VGA, 720 p, and 1080 p. Note that dynamic implementations incur in reconfiguration time overhead (3). Times obtained at 100 MHz.
