AESNI is an SIMD instruction set developed by Intel for the x64 architecture, specifically designed to provide hardware acceleration for the AES encryption algorithm. Anyone who has some understanding of SIMD is generally aware of the existence of AESNI. However, due to the asymmetric structure of AES itself and the special design of AESNI, there … Read more
0. Introduction Both Intel’s CPUs and ARM CPUs have SIMD instructions that enable instruction-level parallelism. This mainly involves knowledge of CPU assembly and some register knowledge. In scenarios involving time-consuming SLAM optimization iterations, such instruction optimizations frequently occur. SSE is short for Intel’s x86 architecture SIMD instructions, while NEON is short for ARM CPU SIMD … Read more
SIMD (Single Instruction Multiple Data) is a technology that uses a single controller to manage multiple processors, executing the same operation on each element of a set of data (also known as a “data vector”), thereby achieving spatial parallelism. It is an important means of program acceleration. This article will briefly introduce some basic knowledge … Read more

The architecture of traditional Digital Signal Processors (DSP) has become inadequate for specific signal processing computational applications. However, the combination of Very Long Instruction Word (VLIW) and Single Instruction/Multi Data (SIMD) architectures can provide the parallel throughput required for high computational performance, with data typically being 16, 24, and 32 bits wide. This is particularly … Read more
