A Scalable Unsegmented Multiport Memory for FPGA-Based Systems

Figure 4

RAM block usage for XOR, multipumped, and banked memories as the number of ports is varied. We used the results of our Omega memory in Table 1 for the banked memory. In this figure we use the minimum number of block RAMs for each internal memory, which is 1 except in the multipump memory where it is 2. This results in the memories having different depths. The XOR memory has a depth of 512 (4 KB memory space). The multipump memory has a depth of 1024 (8 KB memory space). And the banked memory has a depth equal to 512 times the number of ports (16 KB to 128 KB memory space).
