Combined TMS320C6455DSP and FPGA data acquisition platform, this paper describes the C6455 DSP Enhanced Direct Memory Access (EDMA) hardware architecture and configuration methods, focusing on the EDMA applied in two ways, both of which increase the transmission DSP data transfer speed, enhanced the DSP processing power to meet the physical layer of TD-LTEA complex algorithms in real time operations...
In the computer hardware industry, there are currently two highly successful instruction set architectures (ISAs): the CISC x86 ISA which is an established standard architecture in the personal computer and server markets, and the RISC ARM ISA which has become the standard in the fast growing ultra-mobile computing devices market, such as smart-phones and tablets. Program binaries that run on one...
Due to the continuously decreasing cost of FPGAs, they have become a valid implementation platform for SOCs. Typically, a soft core processor implementation is used to execute the software parts of the SOC. As each system is individually designed for a particular application, the idea is natural to support compute intensive parts of the code through customized hardware acceleration. Two different...
ASIP is widely used for the embedded processor design when stringent requirements are necessary such as fast time-to-market, good performance for the killer application and flexibility from software programming. Compound instruction, one type of various ASIs, gives the developers a chance of satisfying those requirements by encapsulating several operations into one instruction. However, encapsulating...
There are several modules with similar structures in a SoC product line. Their contents change a lot in different product and are hard to reuse across projects, which makes similar module design occupy huge resources as brand new one. This paper proposes a methodology to abstract well-verified structures to basic functional building blocks and save them into a library by defining XML Schema. Designers...
The Digital Sound Projector technology provides surround sound with only one speaker, by producing beams of sound. In this paper, we propose an embedded system for joint DTV and Digital Sound Projector, which consists of separate DTV real-time processing and Digital Sound Projector functionality. The verification is done by PC application, by which we analyzed all register's addresses and values.
In this paper, we have proposed an efficient hardware-assisted syntax decoding model for software-based video decoder. The proposed syntax decoding model is a generic model for different video codec standards. The syntax decoding process is divided into codec-dependent high-level syntax parser and generic entropy decoding engines. Currently, the design is implemented specifically for the support of...
