MSC8157TAG1000A is a low power, highly integrated, multi-functional DSP designed for embedded system. With its integrated design, MSC8157TAG1000A is able to perfectly support a variety of embedded integration tasks, including DSP-based audio, communications, multimedia and other signal processing applications. Its dedicated application means that MSC8157TAG1000A is capable of providing high performance and lower power consumption for wide range of embedded designs. Its flexibility also enables it to be used in automotives, consumer electronics, industrial automation and other application fields.

MSC8157TAG1000A has a small package size and its internal structure includes an enhanced Cortex-A35 processor core, vision accelerator, 8KB L2 cache, 8M bit external memory controller, DDR4 memory controller, 32KB L1 cache and OCP interface, which provide a higher energy efficiency and larger memory capacity. In addition, it also has a programmable non-linear-filter acceleration engine, a 4 64-bit vector mathematics unit, and a media processing unit with 4 implementations of CCU. Moreover, the package also includes a PCIe-2.0 controller and a ROM system that support boot-up and verification.

Working Principle

MSC8157TAG1000A uses a combination of several key components to achieve its remarkable performance; the components are as follows: Cortex-A35 Processor Core, 8KB L2 Cache, 8M bit External Memory Controller and DDR4 Memory Controller.

The Cortex-A35 processor core, which is a low power ARMv8-compatible processor, is responsible for controlling execution speed, executing instructions, and managing interrupts. It has access to a 32KB L1 cache and 8KB of L2 cache to ensure that it has enough space for quick data and instruction loading and storage.

The 8M bit External Memory Controller and DDR4 Memory Controller provide the bandwidth needed for typical applications. The DDR4 Memory Controller is able to support a peak interface rate of up to 800 megabytes per second and has a low latency and low power consumption.

The Vision Accelerator, which is an on-chip processor, is designed to process the large amount of data quickly and accurately, and can be used to perform various vision tasks such as object recognition, image filtering, and feature extraction. It also supports various algorithms, including image segmentation, image compression, and denoising.

In addition, the package also includes a 4 64-bit vector mathematics unit and a media processing unit with 4 CCUs in order to support the execution of programs for digital signal processing.

Conclusion

MSC8157TAG1000A is a high-performance and reliable DSP from Tsinghua Academy of Grapheme (TAG). It is suitable for a wide range of application fields and is capable of providing optimal performance for embedded designs due to its low power, highly integrated design and extensive features. Furthermore, its advanced programmable non-linear-filter acceleration engine, 4 64-bit vector mathematics unit, and media processing unit with 4 CCUs make it the ideal choice for digital signal processing.
