| Altera Hones DSP Capabilities with Stratix III FPGAs |
By Jennifer White & Jeff Bier, 12/13/2006
 Altera this November announced its next generation of FPGAs, the Stratix III. The new devices feature enhancements to the DSP blocks in addition to other architectural changes. These enhancements coupled with migration to a 65 nm process should boost the already-impressive DSP capabilities of the Stratix chips.

| Jeff Bier's Impulse Response – Multi-Core Math |
By Jeff Bier, 7/19/2006
Freescale recently introduced a new DSP chip, the MSC8144, that contains four 1 GHz SC3400 processor cores. Freescale characterizes the new chip as being "performance-equivalent" to one 4 GHz core. But is it really? As usual, the answer is, "It depends." It depends on what kind of application you're running, on how you map the application onto the cores, and on how you choose to characterize "performance."

| Case Study: Obtaining the Best Benchmark Results with the Least Engineering Effort |
By Jennifer White & Jeff Bier, 6/27/2006
Typically, processor vendors use their in-house engineering resources to optimize benchmark implementations. This can yield good benchmark results, particularly when the benchmarks are implemented by engineers with intimate knowledge of a processors architecture and sufficient time to do a thorough job. In some cases, though, the processor vendor may prefer to outsource benchmark implementation work. In such situations, vendors often turn to BDTI for benchmark implementation services.

| Custom Benchmarks |
By Jennifer White & Jeff Bier, 5/24/2006
BDTI recently used its expertise to help a major manufacturer of cellular phones analyze competing DSP cores under consideration for baseband processing in its next generation phones. BDTI’s custom benchmarking services enable system and system-on-chip developers to quickly make confident processor choices and architectural decisions, while reducing the benchmarking workload on their in-house engineering resources.

| Jeff Bier’s Impulse Response – Bamboozling with Benchmarks, Part 1 |
By Jeff Bier, 2/22/2006
Good benchmarks play an essential role in evaluating processing engines. Unfortunately, benchmarks are often misused, creating confusion and mistrust. Most people don't set out to use benchmark results deceptively; they may simply be unaware of benchmarking pitfalls. To keep from falling into these traps, we've created our Top Ten list of ways in which benchmarks are abused.
