[2012-09-27] Protocol Analyzer Serial Wire Debug(SWD)_V1.00.00 Publish

Brief Introduction of Application: Since the smart phone and tablet computer become more and more popular, more and more products take the Android platform and higher-level Cortex-M3 chip, that causes the ARM-based chip be wildly used. To satisfy such huge market demand, ARM launched the new Serial Wire Debug(SWD) Bus which is different with JTAG Bus. With its advantages of low power, capacity of accessing multi-devices synchronically and two-wire transmission mode, it is wildly used in cellphone or tablet computer, especially in the controller of single-chip/multi-chip (such as STM32 micro controller). Function Introduction: SWD belongs to serial signal. It has two signal lines: SWCLK and SWDIO. The SWD input or output is determined by the data of both parties in data exchanging, which called Host and Target. SWD is to replace the JTAG interface Bus, it has the same JTAG Protocol and upward compatible. But it takes the CPU Standard Two-wire Protocol of ARM, so its speed can reach to 4Mbps under 50MHz. SWD also supports internal debugging. It provides double-mode program by taking the TMS and TCK line of JTAG interface as the SWDIO and SWCLK signal of SWD. 【DOWNLOAD】
