I'm comparing the SiFive Essential 6-Series and 7-Series cores for a new project. Can you tell me which core offers better performance, what type of processing architecture each uses, if both are Linux-capable, and if the 6-Series supports coherent multicore with a shared L2 cache?
Navigate to the SiFive Essential Family page. From the Essential Family page, identify the DMIPS/MHz performance and architecture type (single/dual-issue) for both the 6-Series and 7-Series, if available. Click the 'View 6-Series' link to navigate to its dedicated page. On the 6-Series page, confirm its Linux capability and whether it supports coherent multicore with a shared L2 cache. Click the 'View 7-Series' link to navigate to its dedicated page. On the 7-Series page, confirm its DMIPS/MHz performance, architecture type, and Linux capability. Synthesize the gathered information to provide a comparative answer addressing all aspects of the task.
State that the 7-Series offers higher DMIPS/MHz performance (Up to 3.3 DMIPS/MHz) compared to the 6-Series (Up to 2.1 DMIPS/MHz). 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. Provide a clear, comparative summary of these features for both core series.
