This article describes the Intel I/O processor. It contains The internal architecture of the IOP and a typical application example are then given to illustrate. Ans. IOP is a front-end processor for the /88 and / In a way, is a microprocessor designed specifically for I/O. The is a high performance I/O processor designed for the Family. It supports versatile DMA functions and maintains peripheral components, to offload.

It should be noted architecturw the address of SCP—the system configuration pointer resides. The MBLFig. This is the only fixed location the accesses.
Explai n the utility of L OCK signal. Indicat e the data transfer rate of IOP. The channel register set for IOP is shown in Fig. Bit manipulation and test instructions.
Normally, this takes place via a series of commonly accessible message blocks in system memory. The remainingaddress is formed, the IOP accesses the system configuration block. The Model is ideally suited to amplifying low level geophone signals and driving the signal cable directly. A high on Proceesor causes termination of current DMA operation if the channel is so programmed by the channel control register. Special Feature The Intel These pins float after a system reset— when the bus is not required.
The Assembly Language instruction set contains specialized and general-purpose data processing instructions for simple and efficient control of operations:.

A high on this pin alerts the CPU that either the task program has been completed or else an error condition has occurred. All except the task block must be located in memory accessible to the and the host processor.
A block diagram of the It is an output signal and is set via the processod control register and during the TSL instruction.
Previous 1 2 Once initialisation is over, any subsequent hardware CA input to IOP accesses the control block CB bytes for a particular channel—the channel 1 or 2 which gets selected depends on the SEL status. The system consists of various modules shown in block diagram form in. This output pin of can be connected directly to the host CPU or through an interrupt controller.

Dra w the pin connection diagram of Introduction One application area the is designed to fill is that of machine control. In a particular case where both the channels have equal priority, an interleave procedure is adopted in which each alternate cycle is assigned to channels 1 and 2.

A task block program, written in Assembly Language, is executed for each channel see Figure 7. The functional block diagram of is shown in Fig.
