+ | ====== Computers with ARM architecture in MLAB brick system ====== | ||
+ | |||
+ | ARM architecture is currently developing rapidly, especially thanks to its excellent computing power with 1 W power consumption in contrast with obsolescent and more complicated Intel Ix86 architecture. This situation has been achieved over the last few years mostly thanks to its massive deployment in devices like tablets and telephones. | ||
+ | |||
+ | There are several computing machines based on this architecture suitable for developmental applications. | ||
+ | |||
+ | ===== Single-board computers ===== | ||
+ | |||
+ | There is already a [[http:// | ||

+ | ==== HardKernel ODROID-C1 ==== | ||
+ | |||
+ | A slightly more robust variant with a slower processor compared to [[en: | ||

+ | {{ : | ||
+ | |||
+ | ==== HardKernel Odroid-U3 ==== | ||
+ | |||
+ | It serves as a substitute for ODROD-X2 that is no longer produced. They have more or less identical parameters, only the PCB is smaller in size and some of the interfaces are no longer present. For more detailed description see [[en: | ||

+ | {{ : | ||
+ | |||
+ | |||
+ | ==== HardKernel Odroid-X2 ==== | ||
+ | |||
+ | {{ : | ||
+ | |||
+ | It is one of the first quadruple-core Cortex-A9 MPCore ARM computers with cores operating at frequencies up to 1.7 GHz. Operation memory 2GB is of PoP type and thus is soldered directly on the CPU chip. For more detailed description see [[en: | ||
+ | This computer contains GPU that does not yet support OpenCL. | ||
+ | |||
+ | <WRAP info> This development board is no longer produced. As a substitute it is possible to use ODROID-U3.</ | ||
+ | |||
+ | ---- | ||
+ | In reality, this computer also has CPU module placed on a separate PCB connected by connectors. The module is glued by epoxide to the main board - a concept similar to EOMA-68, only the CPU module cannot be replaced. | ||
+ | |||
+ | ==== HardKernel Odroid-XU ==== | ||
+ | |||
+ | {{ : | ||
+ | |||
+ | Technically speaking, it is a successor of Odroid-X2 board with a newer CPU 4x Exynos5 Octa Cortex™-A15 1.6Ghz and 4x Cortex™-A7 - all of the 8 cores integrated into one chip. Both types differ significantly in computing power and thus in power consumption. The original idea behind this concept is, that the planner will decide about the usage of cores with low computing power or more powerful cores for running the system (thanks to integration of both CPUs in one case, the tasks can be transferred quickly between the cores). The GPU PowerVR SGX544MP3 already supports OpenCL 1.1 and moreover, there is a USB 3.0 available on the board - an advantage especially when connecting newer versions of SDR receivers. | ||

+ | * Device, into which the card is inserted, contains I2C EEPROM with identification | ||
+ | * It is possible to test and set up the software outside the ‘living’ operating system | ||
+ | * The total costs of specialised hardware construction are cheaper | ||
+ | * It is easy to actualise the computing unit by changing the card | ||

+ | A problem common to all the computers is a mechanical construction that is incompatible not only with MLAB brick system. Another issue is a production instability - most of the computers will not be produced the following year, or at least not in the above-mentioned configuration. Therefore, it will be useful to create an own open-source solution to computing hardware that can be used to build a network of detection and measuring stations. | ||
