Embodiment Construction

[0051] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0052] The acquisition method of a kind of DSP internal memory of the embodiment of the present invention is as figure 1 shown, including the following steps:

[0053]Step s101, downloading the memory commissioning and dispatching module and the memory uploading and receiving module from the PC to the HCP, the HCP is used as a general master control unit in the hardware platform architecture, and assumes roles such as configuration, control, and information transfer of auxiliary units such as DSP, In this device, HCP is connected with DSP and PC through standard peripheral interfaces (ETH, etc.).

[0054] Step s102, when the memory capture condition is met, the memory de...

Abstract

The invention discloses a method for acquiring a DSP memory, comprising the following steps: when satisfying memory capturing condition, a memory test commissioning dispatching module on a host control processor (HCP) uploads a memory capturing preprocessing module, a command analyzing module and a memory uploading module to a reserved space on the DSP; the memory capturing preprocessing module, the command analyzing module and the memory uploading module capture the DSP memory and upload the content of the memory to a memory uploading receiving module on the HCP. The invention also discloses a device for acquiring the DSP memory, and can realize memory acquirement under the normal and abnormal conditions of the system, realize relevant test commissioning analysis of a novel DSP chip without an externally arranged memory direct access port, and improve locating efficiency of problem analysis in the testing stage.

Description

technical field [0001] The invention relates to the technical field of digital signal processing, in particular to a DSP memory acquisition method and device. Background technique [0002] In recent years, with the continuous development of communication technology, especially the wide application of 3G technology and IP technology, the complexity of the corresponding DSP (Digital Singnal Processor, digital signal processing) system is also increasing, supporting more general peripherals Ports, such as ETH (Ethernet, Ethernet port), SRIO (Serial Rapid I / O, serial fast input and output ports), etc. At the same time, some ports in the traditional sense are gradually abandoned by many chip manufacturers, such as HPI (Host-Port Interface, host interface), DSI (Display Serial Interface Specification, display serial interface), etc. These ports are processed in DSP As a host interface in the program design, because of its special direct access mode, it can directly query the DSP ...
