An Embedded Debug Structure for VLIW DSP
Yihe Sun · Microelectronics & Computer · 2010
VLIW is a commonly used architecture in the DSP designing. When developing application program for VLIW DSP,bugs are inevitable. It takes much time for software developer to debug and validate the program. In this paper,we present a hardware debug structure for the VLIW DSP processor,which allows the developer to debug the program on chip. Through the debug interface,we can easily trace the program,change the value of the registers,and control the execution. The debug structure is embedded while designing the DSP.
