碩士 === 國立中山大學 === 資訊工程學系研究所 === 90 === Multimedia workloads have always held an important role in embedded applications. The thesis presents a Multimedia Enhanced MicroController Unit (ME-MCU) for low-cost embedded applications. The main components of ME-MCU include a PIC16C 8-bit MCU core with a 32-bit multimedia extension, an enhanced memory interface fo signal processing, and an embedded In-Circuit Emulator (ICE). The main goal is not only to improve the media performance, but also to keep the small-area benefit of signle-chip microcontrollers. In addition, base on the architecture of ME-MCU, we proposed a reusable MultiMedia Extension SIP (MME SIP) for providing the CPU designers a simple solution to perform the multimedia extension to an exist ISA. A cost-effective multimedia extension to ARM7 microprocessors has been introduced as a case study of MME SIP. The MME SIP is capable of reducing the execution cycle counts by 69% to 81% for several critical loops, with an average speedup of 3.41, while the gate count overhead is kept under 11%.
