bit arithmetic
1.Unlike the popular 8×8 DCT used in previous standards, the 4×4 integer transform can be computed without multiplications, just additions and shifts in 16-bit arithmetic, thus minimizing computational complexity and avoid inverse transform mismatch.
2.Research on image lossless compression method based on adaptive bit-level arithmetic coding
3.At multiplication, the multiplicative arithmetic of 1 bit BCD was improved and presented new arithmetic.
4.This paper proposes a new arithmetic of JPEG decode software basing on the 32-bit ARM7 chip,LPC2292 and applying the arithmetic,a handhold JPEG image displayer is designed.
5.A processing unit feature that provides four 64 bit floating point registers to perform floating point arithmetic calculations.
6.A flag bit in the status register of the central processing unit, used to show a negative result from an arithmetic operation.
7.(5) Based on the 18-bit floating number representation, the improved multiplier, division, adder and comparator is given, and then the floating arithmetic is completed.
