Abstract

See full text

Examples described herein relate to an apparatus comprising a central processing unit (CPU) and an encoding accelerator coupled to the CPU, the encoding accelerator comprising an entropy encoder to determine normalized probability of occurrence of a symbol in a set of characters using a normalized probability approximation circuitry, wherein the normalized probability approximation circuitry is to output the normalized probability of occurrence of a symbol in a set of characters for lossless compression. In some examples, the normalized probability approximation circuitry includes a shifter, adder, subtractor, or a comparator. In some examples, the normalized probability approximation circuitry is to determine normalized probability by performance of non-power of 2 division without computation by a Floating Point Unit (FPU). In some examples, the normalized probability approximation circuitry is to round the normalized probability to a decimal.
