Analysis methodology. The first step was to unpack the KPI calculation formulas into data sets. Most of the KPIs are not available ready-calculated, and an indicator often consists of two or more single data sets. The same data set can be shared by multiple indicators, being referred here as “common data sets”. Therefore when common data sets were identified, and with a list of distinct data sets, it was possible to start collecting and analysing the respective data sources. The following presents two examples of how an indicator is translated into needed data sets. First example is the indicator “Ratio of green and water spaces”, which is defined in the framework as follows “Share of green and water surface area of total land area”. In mathematical notation it would be: (𝑔𝑟𝑒𝑒𝑛 ∧ 𝑤𝑎𝑡𝑒𝑟 𝑠𝑢𝑟𝑓𝑎𝑐𝑒 𝑎𝑟𝑒𝑎) ∗ 100 𝑇𝑜𝑡𝑎𝑙 𝑙𝑎𝑛𝑑 𝑎��𝑒𝑎 From there we can see, that in order to calculate the indicator we need the data sets Green surface area, Water surface area and Total land area. When only a division of two numbers is done, there are not any more requirements for those data sets. They can either be plain values (e.g. Total land area = 690 000 m2), or a spatial feature representing city borders in GIS-format, where the Total land area could then be calculated on the fly. Both data sets have their pros and cons, but in this case will lead into same result. Another example of indicator is “Access to public transport”. Its definition is “% of inhabitants with a public transport stop/transportation connection (train, tram, subway) within reasonable (500m) distance”. The associated calculation formula is: (𝑝𝑜𝑝𝑢𝑙𝑎𝑡𝑖𝑜𝑛 𝑤𝑖𝑡ℎ 𝑎 𝑝𝑢𝑏𝑙𝑖𝑐 𝑡𝑟𝑎𝑛𝑠𝑝𝑜𝑟𝑡 𝑠𝑡𝑜𝑝⁄𝑐𝑜𝑛𝑛𝑒𝑐𝑡𝑖𝑜𝑛(𝑡𝑟𝑎𝑖𝑛,𝑡𝑟𝑎𝑚,𝑠𝑢𝑏𝑤𝑎𝑦)<500𝑚) ∗ 100. 𝑡𝑜𝑡𝑎𝑙 𝑝𝑜𝑝𝑢𝑙𝑎𝑡𝑖𝑜𝑛 The needed data sets are Total population, population data with coordinates and locations of public transport stops/connections. Total population can be a plain value, but locations of public transport stops/connections and population data with coordinates both have to contain exact feature coordinates. Population data needed for this indicator could be for example centre coordinates of buildings, with an attribute telling how many persons live in that building. Then the indicator would be calculated with the following steps:
Analysis methodology. Implementing the Proposed Project would not require any short-term construction activities. Long-term operational activities would involve changes in water supply provided to the Plaintiff Water Contractors. These changes would not require additional worker trips or heavy-duty equipment beyond existing conditions. The proposed changes to SWP water supplied to the Plaintiff Water Contractors would require changes in electricity consumption to provide SWP water to those areas.

Analysis methodology. Both sharing patterns and NoC-data compression opportunities must be analyzed under the same premises and thus they must share the applied methodology and tools. However, they also differ in several aspects. An analysis framework has been built in any case to make these analyses possible. In this section we show the main characteristics of such framework. The steps followed to analyze both issues are similar as can be seen in Fig. 11. First of all, in both cases, we trace memory accesses requested by the cores when running real applications. For the NoC-data compression analysis we perform a second step aimed at simulating the transfer over the NoC of data blocks included in the previously traced memory accesses over the NoC. Finally in both cases, we obtain statistics for the previously obtained traces.
Analysis methodology. An algorithm, that the designer want to translate in hardware, has to be analyzed for several characteristics from the designer point of view. Inputs and outputs of the algorithm, performance issues and the basic data structures and operations are the most important. In addition, the communication overhead for the synchronization of the portions of the algorithm which run in specialized hardware with the aspects that run in software has to be considered, as excessive fragmentation may lead to poor performance (e.g. too many forks/joints for little work done in hardware).Performance issues are very important in the scope of QualiMaster, as performance quality tradeoff is of main importance as it has been analyzed in D 2.1.
