Patent ID: 7596774

Claim:
Hard macro device (HMD) for a subsystem (TMi), said hard macro device (HMD) comprising a processing core (C) provided with at least one time critical input terminal (CIT) adapted to feed it with time critical input data to be processed and at least one time critical output terminal (COT) adapted to deliver time critical output data it has processed, wherein processing core (C) is surrounded at least partly with a connecting interface zone (CIZ) with an external border having one or more sides, the (CIZ) including, i) at least one input group of at least two time critical auxiliary input terminals (AITj), located at predetermined sides on the external border of the (CIZ) and adapted to receive time critical input data to be processed, and at least one output group of at least two time critical auxiliary output terminals (AOTk), located at predetermined sides on the external border of the (CIZ) and adapted to deliver processed time critical output data, the critical auxiliary input terminals (AITj) and critical auxiliary output terminals (AOTk) located at the border of the HMD, ii) an input connecting means (LO) for connecting each time critical auxiliary input terminal (AITj) of said input group to said time critical input terminal (CIT), and iii) an output connecting means (Bk) for connecting said time critical output terminal (COT) to each time critical auxiliary output terminal (AOTk) of said output group.
