Ever wonder why coherent networks are needed beyond server design? The value of cache coherence in a multi-core or many-core server is now well understood. Software developers want to write multi-threaded programs for such systems and expect well-defined behavior when accessing common memory locations. They reasonably expect… Read More
Amid the alphabet soup of inter-die/chip coherent access protocols, CXL is gaining a lot of traction. Originally proposed by Intel for cross-board and cross-backplane connectivity to accelerators of various types (GPU, AI, warm storage, etc.), a who’s who of systems and chip companies now sits on the board, joined by an equally… Read More
Interconnect plays a significant role in the semiconductor design of a SoC; if not architected and handled well, it can lead to an overdesigned SoC impacting on its power, performance and area. Since a SoC generally contains multiple IPs requiring different data paths to satisfy varying latency and performance cycles, it has … Read More
At DAC Jasper presented a seminar with ARM on cache coherency and verification of cache coherency. The seminar is now available online for those of you that missed DAC or missed the seminar itself.
Cache architectures, especially for multi-core architectures, are getting more and more complex. Techniques originally pioneered… Read More
