Parallel Turbine TCAM FPGA Memory Segmentation

The patent divides the TCAM into multiple banks (first bank, second bank, third bank) that can operate independently and be selectively activated. This segmentation allows the system to achieve high-speed search performance when needed while consuming less power by activating only the necessary banks, directly resolving the contradiction between search speed and power consumption.

The patent implements dynamic power management where different banks can be enabled or disabled based on operational requirements. The system can transition between high-performance mode (all banks active) and low-power mode (selective banks active), making the power consumption adaptable to actual search demands rather than continuously consuming maximum power.

By dividing the TCAM into multiple smaller banks, the patent reduces the area required for each individual bank while maintaining overall search performance. The segmented structure allows for more efficient spatial utilization and reduces the total device footprint compared to a single large TCAM block.

The patent introduces a bank dimension to organize TCAM resources, transforming the traditional single-dimension TCAM structure into a multi-dimensional architecture. This allows searches to be distributed across multiple banks, improving performance while reducing the area required in any single dimension.

The patent divides the search operation into multiple parallel banks that can be activated simultaneously. This segmentation enables the FPGA to perform multiple searches in parallel, significantly reducing the effective latency compared to sequential processing, while maintaining the cost benefits of FPGA implementation.

The patent implements a continuous search mechanism where multiple banks can be searched simultaneously without idle time between operations. This eliminates gaps in the search process, maintaining continuous useful action and reducing overall latency while keeping the FPGA implementation cost-effective.

The patent creates a universal TCAM architecture where each bank can handle different key sizes and wildcard patterns through standardized comparison logic. The same hardware structure can accommodate variable-length keys and different wildcard configurations, providing adaptability without requiring separate specialized circuits for each case.

The patent enables dynamic configuration of search parameters including key size and wildcard patterns by allowing the comparison logic to adapt its operation based on input requirements. This parameter flexibility allows the same hardware to efficiently handle diverse search scenarios without increasing structural complexity.
