A vector processor includes a grouping memory functional unit coupled to grouping memory having multiple bins. The vector processor also includes a bitformatting functional unit that performs bit-level data arrangements using any suitable technique or network, such as a Benes network. The vector processor receives and reads an input vector of data that includes portions (e.g., bits) of multiple data streams, and writes each portion corresponding to a respective data stream to a respective bin in parallel using the bitformatting functional unit to align the data. The vector processor also or alternatively receives and reads multiple outgoing data streams, writes portions of the data streams in respective bins of the grouping memory, and intersperses the portions in an outgoing vector of data in parallel, using the bitformatting functional unit to align the data.

A chip with a built-in self-test (BIST) component capable of testing the linearity of an ADC is described herein. The BIST component uses hardware registers to facilitate a sliding histogram technique to save space on the chip. A subset of detected digital codes are analyzed, and DNL and INL calculations are performed by a controller to determine whether any of the digital codes in the subset exceed maximum or minimum DNL and INL thresholds. New digital codes being detected by the ADC are added to the subset as lower-value digital codes are pushed out of the subset, maintaining the same number of digital codes being analyzed as the subset moves from lower codes detected during lower voltages to higher codes detected at higher voltages. A synchronizer and pointer ensure that the subset moves through the digital codes at the same rate as the analog input ramp source.
