A short primer on instruction set architecture

In computer science, an instruction set architecture (ISA) is an abstract model of a computer. It’s also referred to as architecture or computer architecture. Moreover, a central processing unit (CPU), a venue of realization of an ISA, is called an implementation.

Paving the way for the next generation audio codec for the True Wireless Stereo (TWS) applications

The audio market for wireless Bluetooth headsets is growing rapidly. Audio devices using Bluetooth (BT) connectivity are more ubiquitous than ever. People have gotten used to wireless audio systems, and the mobile phone industry is pushing towards a world without audio connectors and cables. The latest trend in wireless headsets and speakers is True Wireless Stereo systems (TWS), consisting of two independent units that are each charged in their own charging case.

Specifying a PLL Part 3: Jitter Budgeting for Synthesis

This white paper is aimed at system architects and physical implementation leaders working on the design of SoCs. It can be confusing to understand the impact of different jitter sources and how to calculate a jitter budget when specifying a digital system. This white paper explains how jitter changes the period of a clock and how to ensure that jitter has correctly been accounted for in the calculations for timing closure.
