Pillow-SIMD is like a skilled craftsman of images, capable of transforming our creative ideas into beautiful images at the fastest speed. Imagine running an online art showcase platform where creators upload various styles of paintings, and we need to preprocess these works to enhance their display. For example, adding artistic frames to the paintings, adjusting … Read more
Dot Product Operation and Multiply-Accumulate The dot product operation is a fundamental operation in DSP applications, commonly used in filter and transformation algorithms. The ARM Cortex-M4 provides efficient multiply-accumulate (MAC) instructions for rapid execution of dot product operations. Example Code int32_t dot_product(int32_t *a, int32_t *b, uint32_t length) { int32_t result = 0; for (uint32_t i … Read more
1. Flynn’s Taxonomy In the classification of computer architectures, there is a method called Flynn’s Taxonomy, which classifies systems based on the number of instruction streams and data streams. According to Flynn’s Taxonomy, there are the following categories:1. SISD – Single Instruction Single DataIn this model, the instruction unit processes only one instruction, and the … Read more
SIMD Implementation for Aho-Corasick on AArch64 The main purpose of this PR is to add a SIMD implementation for Teddy (a key data structure) on AArch64. Previously, Teddy utilized x86-64 SIMD instructions, specifically SSSE3 and AVX2. This PR reorganizes Teddy’s main implementation into a new Vector trait and provides implementations of the Vector trait for … Read more
