A CSPI MAP 6420 array processor and auxilliary memory, hardware and software has been used to develop a FORTRAN-based software package to facilitate user communication between the PRIME 650 host and the array processor. The 6420 system consists of a 5 MFLOP arithmetic processor with a parallel processing IPU for rapid address generation and 4 megabytes of central memory. The operating system (SNAP-III) provides control and communication between the host FORTRAN applications program and the system software. Complete control is accomplished by the insertion of FORTRAN-like commands directly into the user's FORTRAN program. The 6420 can operate in two separate programming modes: (1) as a conventional array processor, (2) as a FORTRAN-subroutine peripheral processor. The latter node can be immediately utilized by those researchers who have little or no familiarity with array processors and their use. The full capability of the array processor (mode (1)) will be utilized for vectorization of algorithms and improvement of overall computational efficiency.
