“…The probability estimation table (PET) utilization provided the high overhead and the bits required for computation. Horrigue et al [11] improved the throughput, operating frequency by reducing the number of bits computation and the memory consumption in [5]. They proposed the novel MQ-decoder architecture that replaced the PET with the small PET ROM.…”

“…The errors in the data stored in the memory of JPEG2000 require the encryption algorithms in the MQ coding, and such type of architecture is called as secure MQ-coder with the parallel operation. The error-controlling schemes [Unequal Error Protection (UEP)] [11] in MQ-coder reduce the additional memory requirements effectively. But, the raise up of bottleneck decreases the throughput adversely in parallel operation.…”

“…• The proposed Auxiliary Minutest MQ-coder (AMMQ) architecture modifies the probability estimation (Q e ) representation defined in [11] to minimize the memory consumption. The modification in probability estimation reduces the bitwise representation from 13 bit to 12 bit that leads to the reduction in occurrence count from 32 to 29.…”

“…The modification in probability estimation reduces the bitwise representation from 13 bit to 12 bit that leads to the reduction in occurrence count from 32 to 29. The minimization in bitwise representation in proposed AMMQ reduces the count of memory elements from (32 9 13) 416 [11] to (29 9 12) 348 that leads to the preservation of silicon (Si) area further in the compact chip development.…”

Embedded Block Coding with Optimized Truncation (EBCOT) used in JPEG2000 standard performs the sequential processing of code blocks for clear images. The employment of Matrix Quantizer (MQ) in EBCOT reduces the computational burden by generating the context decision pair from probabilistic estimation. But, it consumes huge devices and occupies large memory space that leads to the difficulties in hardware design. The bit truncation in MQ-coder reduces the computational complexities that lead to a reduction in the memory space occupation in the hardware platform. This paper proposes the Auxiliary Minutest MQ (AMMQ) architecture for bit truncation in the probability estimation of context decision pair making. The reduction in a number of bits minimizes the slice registers and lookup tables utilization that offers less flipflop consumption to achieve the compact chip development for JPEG2000 compression. Besides, the reduction in computational steps effectively minimizes the time delay and hence the high operating frequency. The comparative analysis of proposed AMMQ-coder architecture with the existing architectures regarding the memory assures the effectiveness of new way of bit truncation scheme in the JPEG2000 compression.
