Blog Review: July 29
By Jesse Allen - 29 Jul, 2020 - Comments: 0

Rambus' Scott Best digs into low-cost attacks against security chips that are often used to gauge how resistant and well-designed they are and defensive countermeasures that can be taken. Mentor's Colin Walls urges embedded developers to put a priority on writing clear, maintainable code and considers when using a higher level language like C++ may be helpful. Synopsys' Scott Knowlton fin... » read more

What’s After 5G
By Bryon Moyer - 20 Jul, 2020 - Comments: 1

This year’s IEEE Symposia on VLSI Technology and Circuits (VLSI 2020) included a presentation by NTT Docomo that looked far into the future of cellular communications, setting the stage for a broad industry shift in communication. This is far from trivial. 5G only just recently entered the commercial world, and — especially with the higher millimeter-wave (mmWave) frequencies — it has ... » read more

Week In Review: Auto, Security, Pervasive Computing
By SE Staff - 17 Jul, 2020 - Comments: 0

Arm's parent company, Japanese tech conglomerate Softbank, reportedly is considering a sale or IPO of its Arm subsidiary, which it purchased in 2016 for $32 billion in cash. Considering that Arm chips are in most smart phones, as well as an increasing number of computers and IoT and edge devices, this development is being closely followed by most of the tech world. Last week, Softbank directed ... » read more

An Expanding Application Space For GDDR6 Memory
By Frank Ferro - 09 Jul, 2020 - Comments: 0

The origins of graphics double data rate (GDDR) memory can be traced to the rise of 3D gaming on PCs and consoles. The first GPUs used single data rate (SDR) and double data rate (DDR) DRAM, the same memory used for CPU main memory. The quest for higher frame rates at higher resolutions drove the need for a graphics-workload specific memory solution. The commercial success of gaming PCs and con... » read more

Moving Data And Computing Closer Together
By Bryon Moyer - 09 Jul, 2020 - Comments: 2

The speed of processors has increased to the point where they often are no longer the performance bottleneck for many systems. It's now about data access. Moving data around costs both time and power, and developers are looking for ways to reduce the distances that data has to move. That means bringing data and memory nearer to each other. “Hard drives didn't have enough data flow to cr... » read more

Power Impact At The Physical Layer Causes Downstream Effects
By Ann Mutschler - 09 Jul, 2020 - Comments: 0

Data movement is rapidly emerging as one of the top design challenges, and it is being complicated by new chip architectures and physical effects caused by increasing density at advanced nodes and in multi-chip systems. Until the introduction of the latest revs of high-bandwidth memory, as well as GDDR6, memory was considered the next big bottleneck. But other compute bottlenecks have been e... » read more

The Evolution Of Ethernet To 800G And MACsec Encryption
By Maxim Demchenko - 01 Jul, 2020 - Comments: 0

Ethernet is a frame-based data communication technology that employs variable-sized frames to carry a data payload. This contrasts with long-haul Optical Transport Networks (OTN) that use fixed-sized frames. The size of Ethernet frames ranges from a minimum of 60 bytes up to 1500 bytes, and in case of jumbo frames, up to 9K bytes. A frame is a Layer 2 data container with the physical addresses ... » read more

Winners And Losers At The Edge
By Ed Sperling - 01 Jul, 2020 - Comments: 0

The edge is a vast collection of niches tied to narrow vertical markets, and it is likely to stay that way for years to come. This is both good and bad for semiconductor companies, depending upon where they sit in the ecosystem and their ability to adapt to a constantly shifting landscape. Some segments will see continued or new growth, including EDA, manufacturing equipment, IP, security an... » read more

Blog Review: June 30
By Jesse Allen - 30 Jun, 2020 - Comments: 0

Cadence's Paul McLellan examines Fully Homomorphic Encryption, which allows for operations to be performed on encrypted data without decrypting it, and why it's now entering the realm of practicality. Mentor's Shivani Joshi explains the basics of using keepouts to prevent the placement of specific or all design items within a specified area and why they can make or break a first pass at crea... » read more

Blog Review: June 24
By Jesse Allen - 24 Jun, 2020 - Comments: 0

Cadence's Paul McLellan provides an overview of the new IEEE 1838 standard for manufacturing test of 3D stacked ICs and how it aims to enable testing of multi-die chiplet-based designs. In a video, Mentor's Colin Walls investigates the scope and lifetime of pointers in embedded applications. A Synopsys writer checks out the latest mobile memory standard, JESD209-5A, and the enhancements i... » read more
