DSP is replacing much of the analog signal processing inside high-speed SerDes because, at 100 Gb/s per lane and above with PAM4 signalling, it is easier to digitise the received signal with a fast ADC and equalise it in digital logic than to do the same work with analog circuits. Digital equalisers scale with each new process node, can be made much longer and more flexible, and behave the same across process, voltage and temperature. Analog doe…

Signal Processing
A SerDes (serialiser/deserialiser) can recover its data in two broad ways. A classic analog SerDes shapes and slices the signal with continuous-time circuits: transmit pre-emphasis, a CTLE, a small DFE and an analog clock and data recovery loop. A DSP-based SerDes digitises the received signal early with a fast ADC and does most of the equalisation, timing recovery and detection in digital logic. Analog designs still win on power and latency for…

FPGA based video processing acceleration means building the video pipeline, such as scaling, filtering, codec stages or neural network inference, directly in programmable hardware instead of running it as software on a CPU or GPU. Because pixels can be processed as they stream in, an FPGA can deliver high, deterministic throughput with latency measured in video lines rather than frames, often at lower power than a general-purpose processor for t…

Signal Processing
The top applications of FPGAs are signal processing, wireless and telecom infrastructure, networking, data centre acceleration (including AI inference), cryptography, aerospace and defence, automotive, industrial control, medical imaging, and test and measurement. What these have in common is a need for high, predictable throughput and low latency, combined with volumes too low or requirements too changeable to justify a custom ASIC. Below are…

Signal Processing
Taking a floating-point representation of an algorithm into a fixed-point representation is an integral step on the path towards implementation. Unfortunately, it is known to be time-consuming, tedious and error prone. This paper from synopsys describes proven methodologies on how to overcome the hurdles, including many useful tips to get you to results faster.

Signal Processing
This book is intended for those who work in or provide components for industries that use digital signal processing (DSP). There is a wide variety of industries that utilize this technology. While the engineers who implement applications using DSP must be very familiar with the technology, there are many others who can benefit from a basic knowledge of its' fundamental principles, which is the goal of this book: to provide a basic tutorial o…
