Embedded processors, provided as a “black box” with pre-loaded applications, have limited capability to expand hardware functionality and in most cases no screen. Drawing upon our legacy and expertise in low power processor design, ARM Cortex processors can provide an optimum solution for embedded computing applications including automotive, digital signage, industrial automation, mass storage networks, and mobile baseband.
Many years ago now (more than I like to admit) I wrote a paper on the hazards of Dhrystone, both in terms of its very narrow scope (the loop has only about 400 instructions, more than 20% of which are within two C library string functions) and because there is absolutely no policing of the strict and clear rules that were originally laid down by the author. At the time it was a very useful exercise, it helped us talk through with customers what to check for so that there was a fair comparison made from product to product. Until quite recently ...
