Interrupts speed tasks, reduce costs News & Analysis 3/28/2000 Post a comment Interrupts in an embedded system usually notify the CPU of some external event that requires immediate attention. An interrupt temporarily redirects the program flow to service whatever condition caused the interrupt.
Hard IP requires noise immunization News & Analysis 3/21/2000 Post a comment Designing an intellectual property (IP) core that is robust enough to be used in many different chips becomes even more challenging in the world of ultradeep submicron-below 0.25 micron.
Right tool mix points to reuse success News & Analysis 3/21/2000 Post a comment By bringing together the right process management, design entry, simulation and synthesis tools, engineers now can build a methodology that supports mixed schematic and language-based design for field-programmable gate arrays (FPGAs).
Productized IP: more than pipe dream News & Analysis 3/21/2000 Post a comment The economic and engineering justifications for leveraging an intellectual-property (IP) business model have not changed in the last five years-the point at which the concept came to the forefront of electronics design.
Hierarchical design flows recognized News & Analysis 3/21/2000 Post a comment The move to system-on-chip (SoC) designs is expected to dramatically increase chip sizes from the already complex 10 million to 20 million transistors to more than 100 million transistors in fewer than five years.
The Barbarians are at the Gates News & Analysis 3/18/2000 Post a comment Digital signal processing is muscling in on sound reproduction, the last bastion of analog as art form. ANALOGnet site director Charles Small outlines how new developments in DSP are resulting in great sound quality from very small enclosures.
Good Physical Layout Takes Black Magic Out Of Power-Supply Design Design How-To 3/18/2000 Post a comment When it comes to switching power supplies, the importance of a good printed circuit board (PCB) layout can't be overstated. Find out which operation factors affect the printed circuit board design, see some good models, and read about possible pit-falls in the design of the switching power supply.
Where does analog live in a mixed-signal world? News & Analysis 3/12/2000 Post a comment The term "mixed-signal," brandished like a brand name, often refers to a range of products that have little to do with analog signal-processing technology or skills. Conversely, the target market for an analog tool set can seem larger if its developers call it a mixed-signal tool. In this installment of the Scarlet A, Steve Ohr defines some differences among mixed-signal, mixed analog-digital and mixed-technology ICs. More than splitting hairs, these differences can often predict how quickly a n
