Embodiment Construction

[0030] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below in conjunction with examples.

[0031] With the development of wireless technology, the complexity and heterogeneity of network facilities are becoming more and more serious. The wireless system based on software defined radio (SDR) platform has become the mainstream due to its advantages of flexible configuration. The core technology of the SDR platform is VLSI for digital signal processing. However, with the development of semiconductor technology to a more advanced 10nm, the cost of chip design and tape-out has increased sharply (the cost of 28-nm tape-out has reached 1.5 million US dollars per time), which has led to a rapid increase in the research and development cost of application-specific integrated circuits (ASICs). Fixed-function ASICs cannot ...

Abstract

The invention discloses an ASIP configuration based on an SDR and facing the internet of things, and a design method of the ASIP configuration. The ASIP configuration is based on SIMD and VLIW kernels and is a multi-kernel heterogeneous configuration, and comprises an operation unit, a register file, a memory access unit, a storage subsystem and a reconfigurable network-on-chip used for data interaction of all units; and the operation unit comprises a floating point multiplication and addition unit, a real number division unit, a fixed point multiplication and addition unit, a complex number arithmetic logic unit and a CORDIC algorithm unit. By combing a low-power consumption wireless multi-mode base-band platform, a multi-kernel heterogeneous ASIP (Application Specific Instruction SetProcessor) configuration facing data signals of the internet of things is provided, the configuration is implemented by means of a high-level ASIP modeling language, and carries out quantitative evaluation on the area, performance and power consumption of the chip by combining an advanced semiconductor process, and is advantaged by being high in efficiency and precision.

Description

technical field [0001] The invention belongs to the technical field of ASIP, and in particular relates to an SDR-based ASIP framework for the Internet of Things and a design method for the framework. Background technique [0002] Application Specific Instruction Set Processor ASIP (Application Specific Instruction Set Processor) is designed specifically for algorithms in a certain field, and can achieve processing efficiency close to ASIC. At the same time, through the programmable instruction set, ASIP can realize the efficient implementation and real-time switching of various heterogeneous algorithms, and can also modify the software to support new algorithms without re-modifying the chip design. Therefore, ASIP can greatly reduce the number of tape-outs, prolong the life cycle of equipment, and have significant economic and environmental benefits. [0003] In recent years, wireless digital signal processing ASIP has become a research hotspot. The University of Michigan p...
