HEVC Improves Mobile Video Performance
The HEVC video standard is a significant improvement over its predecessor, AVC. It delivers the same quality at half the rate, or better quality at the same rate. Implementation is much easier as well.
Compression Requires The Right Tool For The Job 2
A universal encoder for all datatypes, the equivalent of “one tool for all jobs,” would be exceedingly useful. Different encoders such as the WKdm and APAX bring various strengths and weaknesses to different applications, though.
Compress Climate And Physics Datasets By Four To Six Times For Petascale Computing
In high-performance computing (HPC) applications, “time to results” can be directly related to the rate at which numerical datasets, such as climate measurements, are read from disk, as well as the rate at which simulation results, such as 3D physics arrays, are stored to disk drives.
Big Data Plumbing Problems Hinder Cloud Computing 1
Today's trends in big data and cloud computing will lead to huge traffic jams on the Web. Alternative solutions for moving petabytes of data, though, should ease the crunch.
HPC And “Big Data” Apps Tap Floating-Point Number Compression 1
Samplify CEO Al Wegener argues for inclusion of compress-decompress blocks in hardware accelerators for high-performance computers that handle large floating-point arrays.
The Memory Wall Is Ending Multicore Scaling
Analysis of "memory-wall" problems in multi-core systems, with possible solutions
Compression Reduces The Cost Of 4G Wireless Remote Radio Heads
4G has bandwidth problems even between the top and the bottom of each basestation tower. Data compression offers a way to reduce this facet of cellular infrastructure cost.
Compression Reduces The I/O Bottlenecks Of Multicore Computing 2
Samplify's Prism FP can compress floating point data using lossy or lossless algorithms. Reducing data size is handy for moving data through GPUs and other bandwidth limited environments.
Reduce The Cost Of Your CPRI Links For 3G And 4G Wireless
Consider the use of CPRI compression to reduce costs of fiber links from basestation to remote radio head.
As Compression Technologies Reach Their Limits, What’s Next?
Rather than focusing on just the traditional rate-distortion tradeoff, engineers are actively looking for compression algorithms with low complexity and low latency.
Compress CT Samples At 64 Gbits/s
Find out how 4:1 compression can save significant costs on CT scanner

How to Outsource Your Project to Failure 4

This article will address failure to carefully vet a potential manufacturing or “turnkey” partner and/or failure to transfer sufficient information and requirements to such a partner, a very common problem I have seen again and again with my clients over the years, and have been the shoulder cried upon by several relatives and clients in the past....More

Transition from the Academe to the Industry Unraveled 1

There have been many arguments here and there about how short-comings of universities and colleges yield engineers with skill sets that do not cater to the demands of the industry. There have been many arguments here and there about an imminent shortage of engineers lacking knowledge in the sciences. There have been many arguments here and there about how the experience and know-how of engineers in the industry may vanish due to the fact that they can’t be passed on because the academic curriculum deviates from it....More

Small Beginnings 5

About 10 years ago I received a phone call from an acquaintance. He had found a new opportunity selling some sort of investments and he wanted to share it with me in case I was interested. Ken had done fairly well for many years as a contract software developer primarily in the financial services sector. His specialty was writing RPG code. (RPG is often referred to as a write only language.) But he was seeing the handwriting on the wall as the industry moved on to other methods, and saw himself becoming a fossil....More
