Let's Program the Transistors
In VLSI, an SoC is an integrated circuit that contains multiple functional blocks, such as processors, memory, interfaces, and peripherals, on a single chip. The main idea behind the SoC concept is to integrate as many components as possible into a single chip to reduce the size, power consumption, and cost of the final product….
Whenever you want to add something to the kernel code, there are two options – either add your code to the kernel code and compile/build the entire kernel image or compile your code separately and add it to the kernel image later. The first one is the earlier approach that was followed. But, considering the…
To interact with the hardware, driver needs to communicate with the kernel and before that, it must notify the kernel about its presence. This is achieved by the “init” call by which the driver is registered with the kernel and allocated the memory it wants. At the time of system shut down, the driver is…
As briefly discussed in our previous article, device driver is a software that is used to control a hardware device and make it work. It acts as an interface between the user-application and the hardware. Any user-application reaches out to the device driver for any interaction with the hardware device and the device driver checks…
Let us now look at the questions asked in the recent times of interviews of L&T Emsys, a division of L&T Technology Services that deals with embedded systems and software development (and thus, the name L&T Emsys). It is an ECE core company which was incorporated in February 2001 and has three development centres in Mysore,…
FPGA stands for Field Programmable Gate Array. They are programmable integrated circuits made up of a large number configurable logic blocks (CLBs), fixed function blocks and memory blocks which can be used to perform complex digital computations. The CLBs are the basic and most important unit of FPGA. CLBs are made up of Look Up…
“There is Plenty of Room at the Bottom“ A popular talk delivered by Richard Feynman to American Physical Society at California Institute of Technology in the year of 1959. This talk at that time could foresee the possibility of the revolution which has been brought by VLSI today. The term VLSI stands for Very Large…
When someone start dealing with Microprocessor; a very common doubt always strikes out in the initial phase: “What is the difference between Microprocessor and Microcontroller?” Let’s Define both microprocessor and microcontroller and then we will compare them. Microprocessor: We mean by a microprocessor that all the components of a CPU (Central Processing Unit): ALU (Arithmetic Logic…
