Differentiation versus Diversity

Tilera’s Acquisition Means One Less CPU Company

by Jim Turley

Once there was a time when every company had its own unique CPU architecture. Then there was a time when pretty much everyone used the same CPU architecture. Guess which era we’re living in now.

Actually, we’ve experienced both of those extremes multiple times. We have a makings of an industry cycle here. Really early computer companies (Burroughs, National Cash Register, Amdahl, International Business Machines, Data General, Digital Equipment Corporation, etc.) each invented and supported its own proprietary computer architecture. Each processor was implemented in discrete logic and occupied an entire printed-circuit board. Probably several boards, in fact. Software had no commonality at all. IBM machines couldn’t run any DEC software, which didn’t understand NCR code, which was incompatible with DG equipment, and so on.  Read More

Be a Better Programmer

Programmers put the bugs in. So they should get help where possible with tools and training to minimize. One way is to have a very rigid structure across the whole group.
On LinkedIN there was an interesting discussion, and some said: I want my programmi…

Altera's OpenCL SDK allows software programmers to use the FPGA's fabric as easily as they use the processor cores. The same code that runs on an SoC also runs on the largest parts. Altera is also committed to having an SoC in each family so the Stratix 1…

I'd add "Make room for heatsinks." Especially if you're packing the whole FPGA with logic and cranking up the clock, you will need help taking the heat from the chip. I've never regretted allowing extra room for a big heatsink, including board-level mou…
