CMOS microprocessor and microcomputer ICs

Article Abstract:

The use of CMOS chips is spreading to the entire 4-bit and 8-bit microprocessor market and even to the 16- and 32-bit-device market. CMOS chips are used as replacements for NMOS devices and in place of TTL microprocessor parts. Chipmakers are incorporating CMOS in their designs in the classical CMOS form where p-n ratio remains 50:50, in commercial CMOS form where 40:60 or 20:80 p-n ratios may serve, and in specialized CMOS form where a small number of p devices are needed.

Microprocessor development systems

Article Abstract:

Microprocessor development systems are making inroads into the areas that used to be dominated by stand-alone or host-based systems. By using networking concepts, the new development systems support both 16- and 8-bit microprocessors. They also employ multitasking, multiuser operating systems.

IEEE-488 instruments

Article Abstract:

The standardization of GPIB systems according to IEEE-488 has greatly reduced design and software development time. Bus troubleshooting can help eliminate remaining problems. Further standardization would result from following codes and formats recommended by IEEE.
