Excess-3 code is a BCD code. It is a self-complementing code, but not a weighted code. In earlier articles, we have seen decimal to binary conversion, decimal to 8421 BCD conversion and vice versa. In this article, we will learn about Excess-3 code and its conversion. Excess-3, as its name says, there is an excess…
Although all $display, $monitor, $write and $strobe in System Verilog seem to be similar, there is a slight difference. $display is the normal display, which executes its parameters wherever it is present in the code. $write is similar to $display except that $display displays the contents in the next line (cursor moves to the next…

BCD numbers are numerical numbers. So, arithmetic operations can be performed on BCD numbers. Imagine a seven-segment timer display system showing 2 digits for the count of seconds. After every second, the timer should be incremented by 1. This means that the timer display system requires a BCD adder at the backend, whose output is…
Earlier, we learned that BCD code and the binary equivalent of a decimal number are different. In this article, we will learn that how to convert binary to BCD and vice versa. To convert binary to BCD, we will first convert the binary number to decimal and then the decimal number to BCD number. Similarly,…

In one of the previous articles, we learned about Binary Coded Decimal (BCD) numbers. In this article, we will learn about how to convert a Decimal number to a BCD number and vice versa. Decimal number to BCD number Conversion To convert a decimal number to the BCD number, we need to replace every digit…

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 +…
