WebFeb 25, 2024 · This paper introduces a DRAM cache architecture that provides near-ideal access time and non-blocking miss handling. Previous DRAM cache (DC) designs are classified into two categories, HW-based and OS-managed schemes. Hardware-based designs implement non-blocking caches that can handle multiple DC misses using … WebMay 21, 2014 · Using a non-blocking call is simple to understand – typically the task would put itself to sleep for a while then try again. A blocking call is simpler to code and reduces the use of system resources, as the task remains suspended and not in contention for CPU time until the resource is available. We can look at a real example.
