Introduction

Prototyping an ASIC, ASSP, or SoC onto a single FPGA is not without its challenges. You have to deal with differences in ASIC and FPGA architectures, optimize for performance and area requirements, and account for a debug strategy. Unfortunately, this is only the tip of the  iceberg when tasked with implementing an ASIC onto a multi-FPGA platform. Currently, the largest FPGAs have a capacity of roughly 1.5 M equivalent ASIC gates, so when prototyping a chip larger than this, a multi-FPGA strategy must be in place, and several more pitfalls must be accounted … Read More → "A Synthesis & Partitioning Strategy for Effective Multi-FPGA Prototyping"

Exponentials are exciting!

Anything in the real world that follows an exponential curve is a recipe for increased adrenalin production.  If we’re bopping along in our normal linear lives, and we bump into a geometric progression, we (those of us that took math, anyway) naturally expect that we’re in for a short and exciting ride.  Something that happens in twos or fours today will be exploding into the 128s and 256s by the end of the week, and next month will be flaming out in the bazillions.  Although these events can have … Read More → "FPGAs and the IC Bubble"

Over in one of our sister pubs, we did a review of some of the challenges of DDR last year. In particular, DDR3 has some incredible timing subtleties that have to be managed. DDR controllers are available as IP for FPGAs, but they still have to be connected to the memories on the board. And those board connections can seriously affect whether or not the timing requirements of the DDR protocols are properly met.

In keeping with our theme of free stuff (see Embedded Technology Journal, January 27, 2009) we proudly chronicle the newest free alternative for embedded developers: a free Linux-compatible microprocessor. Never has so much been offered to so many for so little. Or something like that.

Here’s the deal. Altera, the world’s second-best-known FPGA company, has struck a deal with Wind River Systems, the world’s second-best-known embedded-software company, to port Linux to Altera’s NIOS II processor. … Read More → "Free Linux Microprocessor*"
