Multi-kernel DSP reconfigurable special integrated circuit system

Abstract

The invention discloses a multi- kernel DSP (digital signal processing) reconfigurable special integrated circuit system, belonging to the technical field of digital signal processing, and comprising: an internal bus, and a control processor kernel, an enhanced direct memory access, an input and output cache, a DSP multi-kernel array, a configuration information cache, a reconfigurable logic unitand an internal cache which are all connected with the internal bus, wherein the DSP multi-kernel array is connected with the configuration information cache and the reconfigurable logic unit througha reconfigurable on-chip interconnection mode and transmits the configuration information and reconfigurable information. The multi-kernel DSP reconfigurable special integrated circuit system can be well combined with an IP multiplexing technology of SoC (System on a Chip), a multi-kernel DSP reconfigurable ASIC (Application Specific Integrated Circuit) takes the DSP multi-kernel array as a core,and simultaneously, integrates IP modules, such as a logic control, an embedded memory, a data interface and the like, thereby being capable of flexibly and efficiently implement large scale computing.

Description

technical field [0001] The invention relates to a device in the technical field of digital signal processing, in particular to a multi-core DSP reconfigurable application-specific integrated circuit system. Background technique [0002] In the field of large-scale computing, the reconfigurable system is a research hotspot of the current architecture, which combines the flexibility of general-purpose processors and the high efficiency of ASIC (special-purpose chip) well, and is oriented to large-scale computing. ideal solution. [0003] Traditional DSP has disadvantages such as low computing speed, non-reconfigurable hardware structure, long development and upgrading cycle, and non-portability. This shortcoming is more obvious when it comes to large-scale computing. ASIC has great advantages in terms of performance, area, and power consumption. However, changing application requirements and rapidly increasing complexity make ASIC design and verification difficult, and the de...
