Single Instruction, Multiple Data, commonly known as SIMD, is a powerful computing technique that enables the simultaneous execution of the same operation on multiple data points. This approach can ...

Input: Memory location n (integer) contains the length of the vector; Vectors X and Y are both 32-bit integer. Process: Y[i] = X[i - 3] + X[i - 2] + X[i - 1] + X[i] + X[i + 1] + X[i + 2] + X[i + 3] ...

この1つの命令で複数の演算器を動かすといいうやり方は「SIMD(Single Instruction stream Multiple Data stream)」と呼ばれる。 図2.6のようにレジスタと演算器のペアを4組並べ、1つの命令ユニットからの命令をすべての組に供給すれば、同じ命令で4つのデータを同時に ...

Abstract: Increasing interests in Bit-serial SIMD Processing-Using-DRAM (PUD) architectures amplify the needs for a compiler to automate code generation, credited to their ultra-wide SIMD width and ...

株式会社リュディアです。今回はフリンの分類と呼ばれているコンピュータアーキテクチャ上の分類方法についてまとめてみます。コンピュータアーキテクチャはコンピュータ内部構造の設計思想のようなものと考えていただけたらと思います。AI専用の ...

Is low-level programming a sin or a virtue? It depends. When programming for using vector processing on a modern processor, ideally I’d write some code in my favorite language and it would run as fast ...

One of the fun parts of the ESP32-S3 microcontroller is that it got upgraded to the newer Cadence Xtensa LX7 processor core, which turns out to have a range of SIMD instructions that can help to ...
