Microprocessor testability

As the level of microprocessor complexity increases to several hundred thousand transistors for a single-chip machine, it is becoming very difficult to test commercially available designs to the level of fault coverage desired by some customers. In order to achieve near 100-percent coverage of single stuck-at faults, future microprocessors must be designed with special testing features (designed for testability). The authors describe the testing problem for microprocessors, including the various methods of generating test sets and their application by the user. A survey of the testability features of some of today's commercially available microprocessors is presented. Suggestions for testability features for future-generation microprocessors are also discussed

Microprocessor prototyping kits

The microprocessor market is expanding at an amazing rate. The only element of this market more surprising than its rate of growth is its escalating number of new vendors. The time has already arrived when you cannot tell the players without a score card. The score cards in the microprocessor world consist of chip sets, memory, I/O controls, specifications, schematics, support devices, and available software for the various microprocessors. These score cards are the prototyping kits that are so popular today.     

Microprocessor pin predicting

We verified that contemporary microprocessors follow a form of Rent's rule as applicable for functionally partitioned circuits and, hence, present far fewer pins than that predicted by the SIA. We have also suggested a correction scheme for application of Rent's rule to recent VLSI circuits that would yield the correct (slower) rate of increase in pin requirements of these circuits. Finally, the reasons for using such a large number of power and ground pins in current VLSI circuits have been elaborated in detail

Microprocessor technology trends

The rapid pace of advancement of microprocessor technology has shown no sign of diminishing, and this pace is expected to continue in the future. Recent trends in such areas as silicon technology, processor architecture and implementation, system organization, buses, higher levels of integration, self-testing, caches, coprocessors, and fault tolerance are discussed, and expectations for further advances are highlighted. How these trends and expectations will drive the markets and applications, and vice versa, is also explored.
