The necessary logic resources required for the beamformer, apodization unit and focusing unit are found to be 1370k, 1122.1k and 246.2k respectively in terms of NAND-2 equivalent gate counts when BRAMs used in the design are taken off-chip. Various beamformer architectures are presented by ...
7.The device of claim 6, where, when determining the first input, the conditional arithmetic logic unit is further to:shift one or more bits of the first operand;produce a mask; andapply the mask to the shifted first operand to determine the first input. ...
11. The logarithmic arithmetic unit according to claim 1, further including: a determination circuit determining whether or not bit data expressing a digit lower than a prescribed digit of said fixed-point part is equal to a prescribed value, and a selection part connected to said determination ...
FIG. 3 shows the details of the first stage of the multiplier 52 (EMUL1). This stage 52 includes an execution unit multiplier sing logic (EMSIGNLOG) which operates on the sign, exponent and mantissa to compute the sign of the result. An execution unit multiplier exception detector (EMEXCD...
