Embedded digital signal processors (DSP) are highly specialized microprocessors designed to perform digital signal processing algorithms in real time and embedded systems. While traditional microprocessors have a general purpose architecture and can operate as a Digital Signal Processor, they are usually not optimized for the computational requirements of digital signal processing. On the other hand, Embedded Digital Signal Processors are customized to the particular algorithm being implemented and thus reduce the overall cost and power of the system. Among these Embedded Digital Signal Processors is the MSC8126TMP6400. This processor is a 64-bit, single-issue, superscalar Digital Signal Processor designed for high-throughput applications. It can achieve impressive speeds with its 3GHz core clock and support for up to 8 levels of out of order instruction execution.

MSC8126TMP6400 Application Field

MSC8126TMP6400 is a 64 bit processor tailored for signal processing application. It contains a vector processing unit that is highly useful for sound and image processing as it can simultaneously process multiple data vectors. The processor can also be used for spread spectrum communication, which provides greater resistance to interference. Its advanced core architecture supports high-speed digital signal processing algorithms and can be used in applications that require real-time processing such as audio, video or image analysis. Some of the major application areas are automated navigation systems, industrial robotics, avionics and military digital signal processing. It can also be used in consumer electronics such as digital cameras, digital television, mobile devices and gaming consoles.

MSC8126TMP6400 Working Principle

At the heart of this processor is a five-stage pipeline: fetch, decode, execute, write-back and instruction commit. The fetch phase is the process of fetching instructions from memory and decoding them. The decode phase decodes the instructions and the execute phase executes the instructions. The write-back phase stores the results of the previous steps into memory and the instruction commit phase commits the changes to the main memory. During the execute phase, the processor also performs vector operations on the data which are particularly useful for computer vision and sound processing. The processor contains an ‘instruction pre-fetch and buffer’ which enhances system performance by allowing more instructions to be executed in parallel.

The MSC8126TMP6400 also features a 64bit memory bus that supports high speed memory access and low latency data transfer. It also includes two dedicated hardware threads that can run different applications in parallel. The processor can be run in different modes such as single-thread, dual-thread and operational mode. In operational mode, the processor is able to intelligently allocate resources such as execution time and memory access between the two threads allowing both threads to run more efficiently.

MSC8126TMP6400 was designed specifically for digital signal processing applications and is an ideal choice for embedded systems that require real-time processing. The processor offers greater power efficiency and can be used in a variety of applications such as image and audio processing, spread spectrum communication and automated navigation systems.
