Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0038] figure 1 It is a flow chart of a host bootloading method for a TigerSHARC DSP chip of the present invention;

[0039] The steps of the host bootloading method for the TigerSHARC DSP chip include:

[0040] Step S1: After the power supply is stable, first set the TigerSHARC DSP reset pin / RESET signal to be valid through the reset circuit to hard reset the TigerSHARC DSP chip;

[0041] Step S2: Delay at least 500ms to ensure that the TigerSHARC DSP chip is hard reset;

[0042] Step S3: Set the / HBR signal of the TigerSHARC DSP to low, and apply for an external bus to the DSP;

[0043] Step S4: Query the / HBG signal of TigerSHARC DSP, if it is low, then the external bus application is successful, go to step S5, if i...

Abstract

The invention discloses a guiding and loading method for a DSP chip host, and relates to the real-time high-speed digital signal processing technology. The method comprises the steps that data and programs are loaded in a specific mode, and on the basis of the loaded specific data, programs and data can be loaded for a DSP chip through an external host, the programs are operated, and the defect that the programs cannot be guided and loaded for the DSP chip host through a host guiding and loading mode provided by a chip manufacturer is overcome.

Description

technical field [0001] The invention relates to the field of high-speed real-time digital signal processing, in particular to the application technology of the TigerSHARC DSP chip. Background technique [0002] DSP chip is an important technical means to realize high-speed signal processing and real-time signal processing, and is widely used in communication, radar, sonar, network and other fields. [0003] ANALOG DEVICE's TigerSHARC DSP chip is a high-performance digital signal processing chip with high core operating frequency and strong computing power, which can be used to process projects with large data streams and multiple computing tasks. TigerSHARC DSP has a static superscalar architecture, supports 32-bit and 40-bit floating-point operations and 8-bit, 16-bit, 32-bit and 64-bit fixed-point processing, enabling the processor to execute 4 instructions simultaneously within one clock cycle, Complete 24 16-bit fixed-point operations and 6 floating-point operations. I...
