Chip startup SiFive has launched four CPU cores optimized for running artificial intelligence models. These new cores, based on the open-source RISC-V architecture, add vector extension capabilities that allow for more efficient parallel processing of multiple data points, significantly accelerating AI model computations. The X160 and X180 are the flagship products, featuring vector processing capabilities … Read more
Following Chapter 2 Oracle Database In-Memory Architecture (IM-2.2) This article is the second part of the IM architecture CPU Architecture: SIMD Vector Processing For data that needs to be scanned in the IM column store, the database uses SIMD (Single Instruction, Multiple Data) vector processing. The IM column store maximizes the number of column entries … Read more
In the design of CPU cores, SIMD (Single Instruction Multiple Data) is a commonly used data parallel processing method that operates on multiple data elements simultaneously through a single instruction to enhance the computational efficiency and speed of the processor. SIMD has a wide range of applications, such as image processing, scientific computing, encryption and … Read more
RISC-V is an instruction set architecture (ISA) for microprocessors, and people’s opinions about it are polarized. This is especially true given the apparent competition between the ARM and RISC-V camps. This makes sense. RISC-V and ARM represent fundamentally different philosophies on how to design RISC chips. RISC-V has a long-term view that emphasizes simplicity, avoiding … Read more
