Grammar Engine

Grammar Engine was founded in 1979 by Dr. Arvind Rana to exploit the emerging 16 and 32 bit microproccessor technology. During the next several years various data communication products were designed by Grammar Engine and a new low cost tool for firmware development was realized in the form of a ROM emulator. This new tool evolved into the PromICE, a flexible memory emulation system from Grammar Engine. With the addition of a virtual serial channel, the PromICE system facilitated monitor-based debugging of target firmware. Soon this concept became a popular alternative to more expensive processor emulator (ICE) based debugging.

Over the past 14 years PromICE has become an excellent tool to enhance the software engineer's productivity. With support from third party debugging tools and in-house applications modified to exploit the virtual serial channel as a debug channel, PromICE has become indispensable for thousands of firmware developers around the world. PromICE supports DIP, PLCC, TSOP, PSOP, SSOP, SIMM, and micro BGA footprints and thousands of ROM, EPROM, EEPROM and FLASH devices and it supports any word size.

With the recent addition of Code (Address) Trace and Code Coverage circuitry, PromICE offers even more versatility. The additional features have turned PromICE into a must have tool for anyone bringing up new target systems for the first time.

Grammar Engine continues to improve its products and services to strive towards its goal to offer the most innovative tools for the firmware developer.
