Can Managed Code be Used for Real Time? Managed code offers many advantages to the developer of embedded devices that must operate 24x7, often using advanced power management features of their CPU. Demands on such software are intensified for real time systems. To keep power consumption low, software needs to be aware of processor state, including sleep, and needs to initialize in microseconds. Yet, the mandate for 24x7 operations means that no shortcuts can be taken; code must not create any ‘stacks’, ‘buffers’ or reserved memory areas it does not clean up. Likewise, software for PXA-native interfaces can be complex and demand significant processing. Tests were run to compare both ‘speed’ of C# to C++, and ‘latency’ associated with the transfer of data across the managed code and unmanaged code boundary since the actual silicon interface is, by necessity, an un-managed environment.
