Embedded Emulator SPEED-BOX MB2100-01-E

In recent years, an increasing number of waterfall-type V-shaped processes have been adopted in sites of embedded system development where programs are growing in scale and becoming more complex (Figure 1). In V-shaped processes, verification (called conformance testing) using the actual device is an important process, as is the extraction of requirements, designing, and building. The demand for on-chip debugging to verify a program on an actual device system is thus growing. Due to the adverse effects of noise, conventional development tools only allowed developers to move the microcontroller being tested by several dozen centimeters even when a special cable was used. Therefore, a special prototype board for debugging that was not the actual system needed to be prepared in some cases. Furthermore, the Flash microcontroller used in debugging was also an evaluation chip for verification instead of an actual device, which made it difficult to evaluate the items that should be checked on the actual system. The new embedded emulator, “SPEED-BOX,”we have developed allows remote debugging as far as 10m from the Flash microcontroller that is to be used in the actual system. It achieves this by connecting with one special signal line for debugging. It therefore offers on-chip debugging for small devices and devices that are installed in small spaces where conventional debugging had hitherto been difficult. SPEED stands for Single Port Embedded Emulator Debugger, which is the system designation for our single-wire emulator debugger. The built-in debugging functions of microcontrollers for SPEED-BOX include a real-time RAM monitoring function capable of realtime memory data read and write without CPU stoppage and a tuning function. In addition, while this product acts as an on-chip debugger, it can be utilized in debugging scenes during the actual building processes when detailed tests are conducted, New Products MB2100-01-E
