Abstract
The utility model discloses an XDS (Extended Development System) 510-based low-cost general digital signal emulator, which consists of a processor, a programmable logic array, a joint test action group (JTAG) module, a processing unit SN74ACT8990, a level self-adaptive module and a main board, wherein the processor, the programmable logic array XC95144XL, the JTAG module, the processing unit SN74ACT8990 and the level self-adaptive module are respectively fixed on the main board through serial ports. The XDS510-based low-cost general digital signal emulator is a TI (Texas Instruments) series DSP (Digital Signal Processing) emulator with the level self-adaptive capability.
Description
Technical field:
The utility model relates to a kind of novel emulator, and particularly a kind of possess interface level adaptation function, the emulator of compatible all dsp processors of TI series.
Background technology:
(the Texas Instruments of TI company, the program debug of digital signal processor Texas Instrument) adopts the universal serial bus of boundary scan specification to carry out (IEEE1149.1 agreement), it is usually said JTAG simulation model, realize that JTAG emulation has two types instrument, be XDS510 type and XDS60 type, XDS510 emulator speed is slow, interface level is single, can not all dsp processors of compatible TI, XDS560 emulator velocity ratio is very fast, the level self-adaptation, the dsp processor that compatible TI is all.XDS560 emulator circuit complexity, the cost costliness; And the XDS510 emulator adopts USB interface, and simple in structure, cost is low, and is easy to carry, is beneficial to large-scale popularization.And there is subject matter in present main flow XDS510 emulator: be bad to the interface level compatibility of each series DSP processor of TI.
The utility model content:
At present the deficiencies in the prior art, the purpose of this utility model is to provide a kind of and possesses the adaptive TI series DSP of level emulator based on XDS510 type emulator.
For achieving the above object, described in the utility modelly be achieved in that based on the low-cost universal signal digital simulator of XDS510
Be made up of processor, programmable logic array XC95144XL, JTAG module, processing unit SN74ACT8990, level adaptation module and mainboard based on the low-cost universal signal digital simulator of XDS510, processor, programmable logic array XC95144XL, JTAG module, processing unit SN74ACT8990, level adaptation module all are fixed on the mainboard by serial ports.
Described in the utility model based on the low-cost universal signal digital simulator of XDS510, the model that it is characterized in that described processor adopting self-carried USB 2.0 interfaces is the processor of CY7C68013A, finish the processing of usb protocol, and the download of program and the control function of processing unit SN74ACT8990.
Described in the utility model based on the low-cost universal signal digital simulator of XDS510, it is characterized in that the JTAG protocol conversion circuitry that described processing unit SN74ACT8990 is an emulator, the emulation command of mainly finishing the standard that processor resolves to is become the data of the JTAG of serial by the data-switching of 16 bit parallels.
Described in the utility model based on the low-cost universal signal digital simulator of XDS510, it is characterized in that programmable logic cells is the read-write control maincenter of emulator systems, finishes management and distribution to the data bus of system.
Described in the utility model based on the low-cost universal signal digital simulator of XDS510, it is characterized in that described level adaptation module adopts SN74CBT3125 logical circuit and MAX964 high-speed comparator as the realization circuit of output with the incoming level conversion.
Described in the utility model based on the low-cost universal signal digital simulator of XDS510, the principle of work that it is characterized in that described level adaptation module is: the output level of XDS510, operation level according to DSP is controlled the supply voltage of SN74CBT3125 logical circuit, thereby the signal level of output is consistent with the dsp processor that is connected, for input signal, 1/2 benchmark of device as a comparison with the DSP operation level, by the MAX964 high-speed comparator, change various level signals into TLL level into standard.

Fig. 2 is the data processor flow process based on the low-cost universal signal digital simulator of XDS510
Embodiment:
As shown in Figure 1, a kind of XDS510 type emulator described in the utility model with USB interface, be made up of processor, programmable logic array XC95144XL, JTAG module, processing unit SN74ACT8990, level adaptation module and mainboard, processor, programmable logic array, JTAG module, processing unit SN74ACT8990, level adaptation module all are fixed on the mainboard by serial ports.
As shown in Figure 2, the data flow of total system is that the debugging software of host side sends to emulator with debug command by the USB driver, emulator is resolved processing command, the JTAG signal that converts standard to by SN74ACT8990 sends to by the digital signal processor of emulation then, the digital signal processor executable operations, the result is returned to SN74ACT8990 by JTAG, by primary processor debugging mode is returned to debugging software by USB again, finish debug process one time.
