Energy-saving advantages of ARM processors-EEWORLD

Collect

To gain insight into this approach, we considered a number of alternatives. For example, specifying the temperature of the connection when measuring power consumption and using a high-frequency oscilloscope and a highly controlled test environment. However, since we were not trying to characterize the chip itself, but to determine the typical power consumption, we decided to use the available hardware and control the ambient temperature instead of the temperature of the connection or a case. Another issue is that the power consumption measurement needs to target devices ranging from as low as 5MHz microcontrollers to the fastest processors on the market today. Therefore, it is also necessary to consider the ability to repeat the measurement in multiple places instead of in a specific environment and independently verify the results. With programmable DAQ, we can easily specify parameters (such as sampling frequency) and then permanently retain all captured data.

In summary, current current graphs for typical power consumption do not depend on a standard process, set of standards, or workload.

EnergyBench provides several tools that can be easily used with affordable hardware to measure typical power consumption using standard methods developed by the EMBC.

ARM CPU architecture and classification description

Today, when compiling mplayer for mx27ads, I encountered the problem of armv5te and armv6 optimization. The default cross compiler supports armv5te and armv6, so the armv6 decoding code of mpeg4 in mplayer is used by default. As a result, the color space conversion error occurs when playing mpeg4 videos on the mx27ads

ARM7 vs ARM Cortex

1. ARM implementation method ARM Cortex is the latest ARM embedded core based on the ARM7v architecture. It uses Harvard architecture and separate instruction and data buses (under the von Neumann architecture, data and instructions share a bus). In essence, the Harvard architecture is more complex physically,

Generally, there is a difference in the level of embedded systems between 8-bit MCU and ARM. ARM is suitable for advanced products with greater system complexity, such as PDA, mobile phones and other applications. 8-bit MCU is suitable for general industrial control, consumer home appliances, etc. due to its simple ar
