Patent CA-2146029-A1 (CA)
Inventor: CHANDLER GREGORY T
IPC: G06F3/06
Filed: 1993-10-04
Abstract: A disk array controller board which utilizes an EISA bus master which is a slave on its internal data bus to allow an advanced drive array controller chip (ADAC) to operate as a master. The ADAC is connected to transfer buffer RAM. The protocol of the internal data bus provides for a cycle to load a host memory address into the bus slave, to provide transfer count information and slave specific information and for a series of data transfer cycles. The local processor is connected to the EISA bus master and the ADAC to control operations and to provide certain information. The ADAC is controlled by structures referred to as command descriptor blocks (CDBs). Each CDB includes information which describes the various addresses, control bits and functional bits used by the ADAC to perform its transfer operations. The local processor directly writes and deposits data forming a CDB into the transfer butfer RAM. The ADAC obtains the CDB, loads the data into registers and then performs operations according to the information contained in these registers until a transfer is done. The ADAC itself performs operations, including automatic stripe scattering and gathering to develop contiguous host memory fields from striped array data. A series of CDBs can be chained so that a complex series of tasks can be developed. In one variation a string of CDBs is developed to transfer data but some data is transferred to the bit bucket, while other data is actually transferred.

Title: Phase detector
Inventor: TAKAHASHI HIDEHIRO
IPC: H04L27/00
Filed: 1994-06-07
Abstract: Disclosed is a phase detection apparatus for accurately calculating the phase of an input digital complex baseband signal point independently of its amplitude value, without requiring any large-capacity arc-tangent table memory and within a practical calculation time.  This phase detection apparatus rotates the phase of the input signal point in a clockwise direction by a predetermined angle and determines whether the rotated signal point agrees with a reference phase point.  If the rotated signal point leads the reference phase point, the signal point is further rotated by an angle onehalf of the predetermined angle.  If the rotated signal point lags behind the reference phase point, the signal point before the rotation is rotated by a half angle of the predetermined angle.   Rotational angles, 180°, 90°, 45°,..., for the individual rotations are stored in a table.  If the rotated signal point agrees with the reference phase point after the rotation processing is performed several times, or, even if the two points do not agree, if all of the rotational angles stored in the table are used in the rotation processing, the sum of the angles rotated so far is output as the phase of the input signal.
