The core components of the computers and smartphones we use every day are the chip instruction sets: Intel’s x86 and ARM. The former occupies over 90% of the computer market, while the latter dominates over 95% of the smartphone market.This situation is frustrating, but suddenly, something called RISC-V has emerged, which does not require licensing … Read more
Central Processing Unit (CPU) The CPU generally consists of a logic unit, a control unit, and registers, serving as thecore of computation and control in a computer. The CPU’s control unit retrieves executable code from memory and converts it into executable instructions, which are then processed by the arithmetic unit. The CPU can be applied … Read more

For most System-on-Chip (SoC) designs, the most critical task is not RTL coding, nor is it creating the chip architecture. Nowadays, SoCs are primarily designed by assembling various silicon Intellectual Property (IP) modules from multiple vendors. This makes managing silicon IP a major task in the design process. Generally speaking, in new SoC designs, less … Read more
