Description
Renesas delivers MARIE_Blade, a ternary CAM search engine designed for network packet classifying. The full-custom CAM memory enables large capacity, high density, and low power consumption. MARIE_Blade can achieve up to 133 Msps in 72-bit/144-bit normal mode (parallel search 266 Msps), 66.5 Msps in 288-bit mode (parallel search 133 Msps), and 33 Msps in 576-bit mode (parallel search 66.5 Msps). The Hierarchical search reduces power consumption. The extended bit, DX test logic, performs a DX test logic search first (primary search), and the DQ pin performs a DQ array search (secondary search). The DQ array's parity bit can be used to check for errors as an additional function.
