In recent years, more and more fields require the use of high-performance, highly integrated DSP devices, and the increasing demand for multimedia processors has increased the demand for DSPs. Therefore, integrated chips based on the MCU+DSP architecture also It came into being, lower cost, smaller package and lower power consumption. It is a “Sunshine Avenue†belonging to DSP or MCU vendors. In the future, they will continue along this new road. Forward. This series of articles will introduce you to the popular MCU+DSP architecture-based processors or solutions on the market.
Freescale DSP56800E
Freescale has been working in the DSP and MCU fields for several years. To meet the market development needs, the company is the first to introduce a new generation of enhanced core 56800E based on the 56800 core. This product can provide dual functions of DSP and MCU on a single core. The 56800E Series DSPs will provide a low-power, low-cost single-chip solution for the growing communications and datacom market applications in industrial, motor control, automotive and convergence. Because this single-core design consumes less power, Freescale has launched a number of new, battery-powered portable applications that require signal processing, such as portable digital audio, Internet devices, and PDAs.

Introduction
Compared to the 56800, the 56800E delivers up to five times better performance, providing a clear product migration path for customers who need more storage, higher code compilation efficiency, and higher MIPS performance. The DSP56800E consists of several functionally independent modules. Including: Data Arithmetic Logic Unit (ALU), Address Generation Unit (AGU), Program Controller, Bit Operation Unit, Enhanced On-Chip Emulation Module (Enhanced OnCE) and System Bus. as the picture shows.
The flexible memory mode is a feature of the DSP56800E architecture, including the following:
Program RAM and ROM module
Data RAM and ROM module
Non-volatile memory (NVM) module
Boot ROM, module that bootstraps the RAM area to execute code
