HSP45256
The function performed by one correlation cell is:
(Di,n XNOR Ri,n) AND Mi,n
where:
Di,n = Bit i of data register n
Ri,n = Bit i of reference register n
Mi,n = Bit i of mask register n
The reference and mask bits are loaded sequentially, N bits
at a time, where N depends on the current configuration (see
Tables 2 and 9). New reference data is loaded on the rising
edge of RLOAD and new mask data is loaded on the rising
edge of CLOAD. The mask and reference bits are stored
internally in Shift Registers, so that the mask and reference
information that was loaded most recently will be used to
process the newest data. When new information is loaded in,
the previous contents of the mask and reference bits are
shifted over by one sample, and the oldest information is
lost. There are no registers in the multiplexer array (see
Block Diagram), so the data on DOUT0-7 corresponds to the
data in the last element of the correlation array. When
monitoring DOUT0-7, AUXOUT0-8, and REFOUT0-7, only
those bits listed in Table 9 are valid.
