The OP seems to be trying to re-implement the Matlab `buffer` function (see their other thread: [Convert buffer function existing in matlab to julia language](https://discourse.julialang.org/t/convert-buffer-function-existing-in-matlab-to-julia-language/98926)). (Apparently they found a Python implementation and are now trying to port that, rather than starting from the spec?) This really seems better to implement via an array or iterator of [views](https://docs.julialang.org/en/v1/base/arrays/#Views-(SubArrays-and-other-view-types)) rather than copies.

See my [suggestion in the other thread](https://discourse.julialang.org/t/convert-buffer-function-existing-in-matlab-to-julia-language/98926/6), which boils down to the one-liner `@views stack([X[i:i+n-1] for i in firstindex(X):n-p:lastindex(X)-n+1])`.
