Guidance, Navigation and Control. Digital Emulation Technology Laboratory. Volume 4. Task 6: Parallel Function Processor Development
Abstract
The DETL (Digital Emulation Technology Laboratory) simulation hardware centers on the development, implementation, and use of the Parallel Function Processor (PFP). The PFP is a 64 processor digital computer for use in computationally intensive applications that can be partitioned into functional blocks. The processors are grouped in two 32 processor clusters running from one common host. Each 32 processor cluster is connected by a crossbar switch. All inter-processor communication takes place over the crossbar(s). Simultaneous transfers may take place independently and switch patterns may be changed every cycle. In order to program the machine correctly, all inter-processor communication and data transfer lengths must be known beforehand. Within DETL, there are two main hardware systems: The PFP and the Seeker Emulator. (The Seeker Emulator is covered in volume 2 of this report.) The two systems are designed to function together as a simulation/emulation facility for kinetic energy weapons systems. The principal objectives of the DETL are as follows: Provide facilities for 6-DOF KEW emulation; Provide real-time capability in excess of 2000 Hz; Provide support for nonlinear functions; Provide real-time emulation of IR FPA seekers; and To provide a facility for testing and verification of GN&C.
