PROGRAMMABLE EMBEDDED SYSTEM FOR ADAPTIVE ACOUSTICS PARAMETER RESEARCH

This paper examines the structure and functional capabilities of the programmable embedded system for adaptive acoustics parameter research – AMES (Acoustic Measurement Embedded System). The core implementation platform is the PSoC 5 LP programmable system-on-chip, which provides extensive software control over acoustic parameter measurement processes. A mixed-signal conversion method based on selective charge amplification is proposed, enhancing noise immunity and measurement accuracy.

Improving Code Compression for Arm Cortex M Microcontrollers Using Pre- Filtering

For last decades code size is no longer a concern except small embedded systems. ARM Cortex M is a typical microcontroller architecture of such systems. A simple yet effective approach based on pre- filtering Thumb2 binary code is proposed to improve code compression by the general purpose Deflate algorithm. It transforms BL (branch and link) instructions pointing to the same effective address before compression, and restores original opcodes after decompression.
