  2. Random-access memory - Wikipedia

    en.wikipedia.org/wiki/Random-access_memory

    A different concept is the processor-memory performance gap, which can be addressed by 3D integrated circuits that reduce the distance between the logic and memory aspects that are further apart in a 2D chip. [39] Memory subsystem design requires a focus on the gap, which is widening over time. [40]

  3. Average memory access time - Wikipedia

    en.wikipedia.org/wiki/Average_memory_access_time

    A model, called Concurrent-AMAT (C-AMAT), is introduced for more accurate analysis of current memory systems. More information on C-AMAT can be found in the external links section. AMAT's three parameters hit time (or hit latency), miss rate, and miss penalty provide a quick analysis of memory systems. Hit latency (H) is the time to hit in the ...

    Performance and memory profiler that identifies time-intensive functions and detects memory leaks and errors. Proprietary gprof: Linux/Unix Any language supported by gcc: Several tools with combined sampling and call-graph profiling. A set of visualization tools, VCG tools, uses the Call Graph Drawing Interface (CGDI) to interface with gprof.

  5. Memory timings - Wikipedia

    en.wikipedia.org/wiki/Memory_timings

    Because system performance depends on how fast memory can be used, this timing directly affects the performance of the system. The timing of modern synchronous dynamic random-access memory (SDRAM) is commonly indicated using four parameters: CL , T RCD , T RP , and T RAS in units of clock cycles ; they are commonly written as four numbers ...
