I need to choose between the SiFive Essential 6-Series and 7-Series cores for a new project. Which core offers higher DMIPS/MHz performance and a dual-issue superscalar architecture? Also, confirm if both are Linux-capable and if the 6-Series supports coherent multicore with a shared L2 cache.
Navigate to the SiFive Essential 6-Series product page. Extract the DMIPS/MHz performance, Linux capability, and coherent multicore/shared L2 cache information for the 6-Series. Navigate to the SiFive Essential 7-Series product page. Extract the DMIPS/MHz performance, Linux capability, and confirm the dual-issue superscalar architecture for the 7-Series. Compare the extracted features to answer the user's questions.
State that the 7-Series offers higher DMIPS/MHz performance (Up to 3.3 DMIPS/MHz for 7-Series vs. Up to 2.1 DMIPS/MHz for 6-Series). Confirm that the 7-Series features a dual-issue superscalar architecture, while the 6-Series is single-issue. Confirm that both the 6-Series (U6 only) and 7-Series (U7 only) are Linux-capable. Confirm that the 6-Series is coherent multicore capable with shared Level 2 cache.
