Introduction to I2C Bus: I2C stands for Inter-Integrated Circuit. Philips Semiconductors developed I2C in the early 1980s as a low-cost solution for connecting lower-speed peripheral ICs to processors and microcontrollers over short distances. Since then, I2C has evolved into a worldwide standard for communication between devices in embedded systems. The simple two-wire design can be […]
I2S Protocol Introduction Today’s digital systems – from the Digital TV in the living room, Alexa, and google home for playing music and switching from text-based search to voice-based search– are driving convergence on many fronts. Quality of Experience is taking center stage. Audio requirements in Computers, Mobile Handsets, and Home Automation products have changed […]
Difference between I2C vs I2S What is I2C Protocol? I2C stands for Inter IC communication. I2C is a simple two-wire protocol used to comminute between two devices or chips in an embedded system. I2C has two lines SCL and SDA, SCL is used for the clock, and SDA is used for data. I2C Timing Diagram […]
The Differences between eMMC and UFS are: What is eMMC Protocol? Embedded multimedia card or eMMC, is a NAND flash memory for mobile applications and a memory solution for consumer electronics such as tablets, smartphones, GPS systems, eReaders, and other mobile computing devices. What is UFS Protocol? Universal Flash memory or UFS is the next […]
INTRODUCTION A startup was working on AI Edge-based voice processor chip. The voice-based AI chip is designed to consume the lowest power as it’s used in consumer headphones or earbuds. The startup was about to tape out the chip and was preparing for a post-silicon bring-up. It faced very significant barriers in the development phase […]
Where is Logic Analyzer used? Embedded System Testing : Embedded Systems have multiple devices and each of the devices uses the bus to communicate with the main chip or processor and other devices in the system. The Embedded system generally has SPI and I2C devices to communicate with the main processor. A logic analyzer can […]
SPI Protocol: Introduction SPI stands for Serial Peripheral Interface and it is a synchronous serial communication interface used for short-distance communication. SPI interface was developed by Motorola in the 1980s to be primarily used in embedded systems and since then it has become a de facto standard. SPI interface is widely used in SD cards, […]
Introduction HDMI is a digital replacement for existing analog video standards. It is termed as the catalyst for the DTV revolution. The DTV revolution is driving the HDMI standard to support an increase in data speed to higher video resolutions to meet emerging needs. As a result, design and validation engineers need tools to improve […]
UART Protocol: INTRODUCTION UART stands for Universal Asynchronous Receiver Transmitter. A UART’s main purpose is to transmit and receive serial data. UART was developed by Gordon Bell at Digital Equipment Corporation in the 1960s. UARTs are used in automobiles, smart cards, and SIMs in which they are commonly integrated in microcontroller chips. In UART communication, […]
QSPI Protocol: Introduction Quad Serial Peripheral Interface (QSPI) is a serial communication interface. QSPI has been specifically designed for talking to flash chips. QSPI is useful in applications that involve a lot of memory-intensive data like multi-media and on-chip memory is not enough. It can also be used to store code externally and it can […]
