The drive model belongs to the built-in connections of computer technology and is designed to increase the performance of personal electronic computers (PCs) of the PC / AT type, which have in their design an ISA bus, an empty slot and sufficient space for the size required by the pop-up module installed.

Similar foreign computational modules are known as accelerators (hereinafter referred to as modules): NUMBER SMASHeR-860, AL860, Star-860. They consist of a microprocessor, a memory unit and a communication device (adapter) with a PC type PC / flT / 1 /. In this case, the microprocessor is connected to the memory block by a 64-bit data bus and a 32-bit address bus. Modules are implemented constructively on one board.

The disadvantage of these modules is a single-board version of the implementation, which does not allow to implement fully throughput

The closest in technical essence to the described model is the iSPC-860/1 / module. This accelerator module consists of a microprocessor, a memory unit and a communication device with a PC / YT type personal computer. In this case, the microprocessor is connected to the memory block with a 64-bit data bus and a 32-bit address bus. The accelerator module is made on two multilayer printed circuit boards, each of which cannot be modified (modernized) without changing the other, since each board is not a functionally complete assembly. In this case, the accelerator module is powered through the connector of only one board.

The disadvantage of the prototype is that each board cannot be modified (modernized) without changing the other, since each board is not a functionally complete node, and the accelerator module is powered by the connector of only one board.

The technical problem to be solved is the expansion of computational capabilities, increasing the speed of PC / YAT type computers.
