Using NI PXI Modules for Digital Signal Processing Microprocessor Testing

“…To test the efficiency of resulting external memory controller radiation behaviour researches of the DSP processor TMS320C50 (Texas Instrumenrs) were conducted in comparison with the use of DMA controller unit [16]. Functional control was consisted of testing internal memory blocks: 1) at maximum frequency (about 50 MHz), 2) using DMA interface (up to 100 kHz).…”

“…The external memory interface was developed on the basis of hardware and software system, as described in [16] with the use of such modular devices as:…”

“…Modular devices are connected to a personal computer using PXI-1033 chassis. The main advantage of the hardware-software complex [16] is its versatility, which is achieved mainly by developing motherboard shown in Figure 1, which is connected to used NI PXI modules. Thus, in order to prepare for the testing of a new chip, only adapter board with standardized connectors must be manufactured.…”

“…This makes the creation of a versatile and flexible system for testing different DSPs an especially relevant problem. The application of NI PXI-7841R reconfigurable I/O module for testing microprocessors is shown in [16]. This solution is based on the implementation of the direct memory access (DMA) controller interface.…”
