Architecture of SDIO ( Secure Digital Input Output) Host Controller
Introduction:The popular chipset connectivity solutions are UART, SPI and I2C. The oldest andpopular chipset connectivity solution is UART. However, UART is a asynchronousinterface and it does not support data rate beyond 5Mbps. Secondly,we have SPIinterface . The main advantage of SPI interface is,it...
Verilog HDL Interview Questions
Here are some of the important interview questions on Verilog HDL which are frequently asked during interview in Semiconductor industry.1) What are the different Data Types in Verilog HDL ? Ans: There are two groups of data types in Verilog , namely Physical and Abstract.Physical Data Type: -.Net ( wire, wand, wor, tri, triand, trior ). Default value is Z. Used mainly in structural modelling..Register(reg)....
Advanced Digital Design Concepts (Real Problems)
1) Below is a Top level block diagram of a Design. What could be the problem with this Design?Ans - The above circuit diagram shows an invalid design where a NAND gate exists at the top level, between two lower-level design blocks. Optimization is limited because synthesis tools such as Design Compiler...
Bluetooth Low Energy (BLE) Link Layer Operating States (v4.2/v5.0/v5.1/v5.2)
The operation of the Link Layer can be described in terms of a state machine.BLEv4.2: Standby: The Link Layer in the Standby State does not transmit or receive any packets.Advertising: The Link Layer in the Advertising State will be transmitting advertising channel packets and possibly listening to...
Design of Cache Controller
Understanding importance, working principle and associated terminologies of Cache ControllerBasics of Cache Memory - Idea:-> Some data is important and frequently used by processor.-> Most data is not needed.-> Keep the important data in CACHE!!Benefits: -> Faster access to frequently used...
Low Power VLSI Design (Basic Concepts)
Introduction:- During Desktop PC design era VLSI design efforts were mainly focused on optimizing speed to realize computationally intensive real time functions such as video compressing , graphics, gaming etc. While these solutions have addressed the real time issues still the increasing demand of portable operations where the mobile needs to pack all these functions without operating much power...
