Abstract—One of image compression algorithms is block truncation coding that has lower efficiency in compare with some other algorithms, for example, JPEG and JPEG2000, but also has low cost and complexity and can be used in many applications. Many of image compression algorithms were implemented using FPGAs to work in fast digital systems. In this paper, BTC is implemented using some parallel microcontrollers that have acceptable speed and very low cost. AVR microcontroller has many applicable instructions, but has not the division instruction. Using the proposed division algorithm in this paper, this operation can be executed very fast.
Index Terms—BTC, block average, bit map, AVR microcontrollers, division.
