There are different types of BCD codes; however, the 8421 code is the most popular one. In this article, we will highlight three different types of BCD codes, such as 8421, 2421, and Excess-3. Both 8421 and 2421 are weighted code, whereas Excess-3 is not weighted. The above table shows the binary code groups for…
You must have seen the digital clock in the railway station or at many other places. The hour, minute and second digits are seven-segment displays that deal with binary coded decimal (BCD) numbers. In this particular article, we will learn about the BCD code. BCD is a way to express each decimal digit in binary….
More than 1000 cores on a commercial chip – seems unbelievable!!! However, the highly sophisticated manufacturing processes, unbelievably optimized design integration, and the RISC-V open-source hardware revolution have made this possible. Esperanto‘s ET-SoC-1 Chip is a Supercomputer-on-Chip that integrates more than 1000 RISC-V cores on a single die of 570 mm2 area. Dave Ditzel, Founder…
In order to convert a decimal number to a binary single-precision floating point number, first of all, we need to convert the decimal number to its binary equivalent (unsigned magnitude form). A proper sign should be added based on the sign of the decimal number. But remember, we should not perform the signed representation. Then…

In the previous article, we have seen the representation of a binary number in IEEE 754 single-precision floating point format. In this article, we will do the reverse process, which means determining the value of a binary number from a floating-point representation. For this, we will use the following formula: Binary Number = (-1)S(1 +…
In the previous article, we got an overall idea about the representation of floating point number. In this article, we will specifically focus on the single-precision IEEE 754 representation of floating point numbers. Single precision format represents any floating point number in 32 bits. The following figure shows all the parts of the single precision…

Imagine you have a processor with registers of size 32 bits. Can the processor store a number larger than 32 bits in one register? It is possible if the number is represented in floating point format. The floating point format is useful in representing very large and very small integer numbers without increasing the number…
Though the computers store everything in binary format, the user interface deals with the hexadecimal format for ease of understanding. For a human, it is easy to deal with hexadecimal than the stream of ones and zeros. So, in this article, we will study the arithmetic of hexadecimal numbers. One way to perform hexadecimal arithmetic…
We have learned from the article “addition of 2’s complement signed binary numbers” that overflow occurs if the carries into and out of MSB are different. In this article, we will solve some examples that highlight how to detect overflow and how to avoid overflow. Example: Perform the following binary addition in 2’s complement arithmetic….
Chip shortage is a semiconductor crisis that occurs when global demand for semiconductor chips is much more than production. Chip shortage can happen for multiple reasons. And we already know the major reasons behind the global chip shortage 2020-21. Let’s discuss a few interesting facts about the global chip shortage 2020-21. There are many more…
