Ncore application

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

CXL Verification

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


Taming The Interconnect In Real World For SoCs

Taming The Interconnect In Real World For SoCs
by Pawan Fangaria on 12-13-2013 at 1:30 pm

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


Cache Coherency and Verification Seminar

Cache Coherency and Verification Seminar
by Paul McLellan on 07-27-2011 at 5:45 pm

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
