System-on-chip SoC and data processing method suitable for SoC

Abstract

The invention provides a system-on-chip SoC and a data processing method suitable for the SoC. The system-on-chip SoC comprises a peripheral unit, a first direct memory access controller DMAC,a neuralnetwork processor NPU, a static random access memory SRAM and a second direct memory access controller DMAC, wherein the peripheral unit and the first direct memory access controller DMAC are positioned on a first bus, and the neural network processor NPU, the static random access memory SRAM and the second direct memory access controller DMAC are positioned on the second bus; the first bus is connected with the second bus through an asynchronous bridge; the data bit width of the first bus is smaller than that of the second bus; a read channel and a write channel of the second bus are separated. According to the system-on-chip SoC and the data processing method suitable for the SoC located on the first bus, the NPU special for data calculation is added, so that the data processing efficiency can be improved; the second bus is added on the basis of the first bus, different buses can be accessed, so that the pressure of each bus is relieved, and meanwhile, due to the characteristics that the read channel and the write channel in the second bus are separated, and the data bit width is larger, the data carrying efficiency of the DMAC is greatly improved, and the performance of the buses is improved.

Description

technical field [0001] The invention relates to the field of integrated circuit data processing, in particular to a system-on-chip SoC and a data processing method applicable to the SoC. Background technique [0002] With the improvement of the integrated circuit technology level, the chip is also developing in the direction of high speed, multi-function, low voltage, low power consumption, portability, and high reliability systemization. System-on-chip SoC (system on chip) also came into being. The so-called SoC chip refers to an IC with system functions such as integrated digital and analog mixers, signal acquisition and conversion, I / O interfaces, memory, MCU and DSP on a single chip. SoC chips have become the focus of IC design circles because of their rich resources on-chip, high integration, small size, and great flexibility in use. [0003] With the development of deep learning technology, more and more companies apply SoC chips to the field of data processing. For...
