VSB - Parallel Sub-system Bus of the IEC 60821 VMEbus

The VSB bus was designed to meet the needs of multiprocessor systems based on high-performance 32-bit microprocessors built up from board assemblies. lt includes a high-speed asynchronous data transfer bus allowing masters to direct the transfer of binary data to and from slaves according to 4 kinds of cycles: address-only, single-transfer, block-transfer and interrupt-acknowledge cycles. It also includes an arbitration bus enabling arbiter modules and/or requester modules to coordinate the use of the data-transfer bus according to two arbitration methods (series or parallel).
