音视频领域有个 M x N问题

不同的media processors 在N种平台上导致api复杂度上升不可维护

考虑一种接口设计方法，让代码更简练

琢磨半天结果是concept + boost pfr之类的检测接口/策略模版

constexpr and consteval functions https://biowpn.github.io/bioweapon/2024/02/17/constexpr-consteval-function.html

// This is a pure compile-time function.
// Any evaluation is fully done at compile-time;
// no runtime code will be generated by the compiler, just like `static_assert`.
consteval size_t strlen_ct(const char* s) {
    size_t n = 0;
    for (; s[n] != '\0'; ++n);
    return n;
}

// This is a pure runtime function, which can only be invoked at runtime.
size_t strlen(const char* s);

// This function can be invoked both at both compile-time and at runtime,
// depending on the context.
constexpr size_t strlen_dual(const char* s) {
    if consteval {
        return strlen_ct(s); // compile-time path
    } else {
        return strlen(s);    // runtime path
    }
}

https://johnnysswlab.com/a-story-of-a-very-large-loop-with-a-long-instruction-dependency-chain/

简单来说就是拆循环 loop fission + 降低数据buffur大小，小于l1 cacheline，提升性能

需要复现一下

如何发现是内存子系统的问题（buffer大于cacheline）？ 使用likwid 查的。这个实验需要复现一下看看

简单来说就是通过 interleave 拆分任务，来加速，这个和loop fission还不太一样，loop fission就是单纯的拆循环，interleave又不同任务分发调度的感觉

https://en.wikipedia.org/wiki/Parent_pointer_tree 这个要看他的segment stack怎么写的

另外就是性能要测试一下

TerensTare/modern_bloom 挑刺儿一下

当我们实现bloom filter都需要注意什么？
