[Technology Report]
Design Languages Vie For System-Level Dominance
There's change in the wind for designers as IC geometries shrink and transistor counts rise. Design methodologies must move with the physical silicon. Clearly, hardware-description language-based methodologies increasingly are a hindrance to...  — David Maliniak

[Product Innovation]
Eradicate Hardware And Software Bugs On Multicore SoCs
System-on-a-chip (SoC) designs have emerged as system-critical solutions to reduce size, complexity, power, and cost. Additionally, technology improvements over the last few years have allowed SoC solutions to grow more complex. Relatively...  — Dave Bursky

[Design Application]
Ease The Debugging Of Serial Peripheral Interfaces
Embedded systems are becoming less expensive and smaller as they grow more complicated. This is partly due to specialized peripherals often connected to a controller using a serial interface. Although numerous proprietary serial interfaces still...  — Contributing Author

[Ideas For Design]
Switch-Debouncer IC Creates A Long-Period Timer
One major application for long-period timers is in remote weather-data stations. These stations measure environmental conditions at regular time intervals and transmit the results to a central collecting facility. Since these small weather stations...  — Phill Leyva

[Ideas For Design]
Single-Wire Sensors Interface Directly To A PC
Over the years, various vendors have developed a number of interfacing techniques to help address design requirements for simplified signal conditioning, reduced component count, and lowered development and system costs. One such low-cost...  — Contributing Author

What's All This Algebraic Equation Stuff, Anyhow? (Part 1)
You guys may have noticed that recently, I have been showing you a lot of algebraic equations. I really don't like to use, or generate, algebraic equations. Sometimes they're much messier than just doing numerical evaluations. For...  — Bob Pease

[Embedded in Electronic Design]
On-Chip Debugging
Bill: Today we have the hardware hooks to debug processors with on-chip memory. But it's not enough. Code size and chip clock rates have risen, so we need better on-chip debugging resources. Ray: Don't forget, it's the...  — Ray Weiss , et al.

ARM On-Chip Debug Hardware
ARM, one of the twenty-first century microprocessor standards, has a major presence in SoCs. A 32-bit RISC, it was designed for mid- to low-level applications. It was also designed for low-power operation. Vendors can license the ARM...  — Ray Weiss , et al.

[Embedded in Electronic Design]
PowerPC On-Chip Debug Hardware Resources
The PowerPC started out as a RISC challenger to the PC's XC86, developed by Apple, IBM, and Motorola. It lost that race, but it has become a major RISC for ICs, ASSPs, and cores. PowerPCs have a large embedded base in printers, telecom, control, and...  — Ray Weiss , et al.
