The 1553 Advanced Communication Engine (1553-ACE)

The next-generation 1553 terminals will address the concerns of reducing the size, power, and cost and adding features required to off-load the system designer. The 1553-ACE series programmable terminal and the BUS-61580 ACE terminal are described. The various features incorporated especially the programmable options which make this series terminal so flexible are discussed. The ACE series has an advanced set of registers, internal 4 K words of shared RAM, dual encoder/decoders, and three-state buffers for address and data I/Os in one monolithic. It has selective I/O features, such as buffered DMA, or a shared RAM interface, with or without zero wait states to support a variety of microprocessors. Additional programmable features incorporated are RT circular data stacks programmed by individual subaddress, internal RAM command illegalization, and advanced bus controller and bus monitor options for bus snooping or for selective monitoring. The electrical, mechanical, and special competitive features of the 1553 ACE-series are highlighted. The military screening and mechanical specifications and other product options are covered.<
