....The system controlling finite automaton must supply all these 60 control signals. These are placed in registers accessible to a host PC which, as said, is used as this automaton. 5.5. 3 The interface The host PC is interfaced via a standard 16 bit I O channel at the PC AT (ISA) bus (Eggebrecht [68]) In addition to the 60 odd digital handles that controls the RTRL back propagation system, the host PC also must provide various analogue control signals that are likely to be changed by the user. For instance learning rate and neuron activation steepness control signals. Most of these are ....

....there is presently a gap between message passing primitives and their implementations, as illustrated in Figure 1. For some architecture and protocols, some abstract communication primitives do exist, though most fall far short of send receive primitives; for example, ISA bus transfers of a PC [3] are achieved using in and out assembly instructions, and serial transfers of an Intel 8051 are achieved by configuring several registers [4] For other architectures and protocols, direct port manipulation is necessary, such as for most transfers for an FPGA or microcontroller. This gap means ....

....particular protocol, the PC ISA bus, demonstrate their practical use on two examples, and show why some routines in addition to just send receive are necessary to support somewhat complex examples. 2 ISA communication The PC XT AT bus, also called the industry standard architecture (ISA) bus [7], supports 8 and 16 bit datapaths, and 20 to 24 bit addressing. Today s increasingly popular PCI standard includes within the PCI subsystem, a PCI ISA bridge that supports the current 8 and 16 bit peripherals used in PCs. Most PC cards are ISA compatible. The PC is typically the master of the bus, ....
