EDACafe Weekly Review February 18th, 2018

Intel far surpasses others with R&D spending of $13.1 billion in 2017 and accounts for 36% of expenditures among Top R&D spenders.

The ten largest semiconductor R&D spenders increased their collective expenditures to $35.9 billion in 2017, an increase of 6% compared to $34.0 billion in 2016. Intel continued to far exceed all other semiconductor companies with R&D spending that reached $13.1 billion. In addition to representing 21.2% of its semiconductor sales last year, Intel’s R&D spending accounted for 36% of the top 10 R&D spending and about 22% of total worldwide semiconductor R&D expenditures of $58.9 billion in 2017, according to the 2018 edition of The McClean Report that was released in January 2018. Figure 1 shows IC Insights’ ranking of the top semiconductor R&D spenders, including both semiconductor manufacturers and fabless suppliers.


Figure 1
Intel’s R&D expenditures increased just 3% in 2017, below its 8% average annual growth rate since 2001, according to the new report. Still, Intel’s R&D spending exceeded the combined R&D spending of the next four companies—Qualcomm, Broadcom, Samsung, and Toshiba—listed in the ranking.

Floating point
February 15, 2018  by Colin Walls

Nowadays, most embedded systems are built using 32-bit CPUs. These devices give plenty of scope for performing the arithmetical processing required for various applications. Calculations can be performed on signed or unsigned integers and 32 bits gives a good range of values: +/- 2 billion or up to 4 billion respectively. Extending to 64 bits is reasonably straightforward.

If you need to stray outside of these ranges of values or perform more sophisticated operations, then you need to think in terms of floating point and this presents a range of new challenges …
