Table 2 Occupied memories that are used by RNS-based DB2 DWT approaches. The input word length, w, is 16 bits and b=3∗n+1
From: An optimized two-level discrete wavelet implementation using residue number system
Approach | Occupied memories | |
|---|---|---|
a = 8 | a = 4 | |
Memory-size | (8×b) | (4×b) |
One-level | 8 | 16 |
Two-level | 16 | 32 |
Optimized FCMA (memory-based) | 24 | 36 |
Optimized FCMA (shift-based) | 0 | 0 |
