This is a copy of the ***INMOS*** 'Product Update' published in the SERC/DTI Transputer Initiative Mailshot (November 1989). And I beleive this is the only official information INMOS have released. Enjoy :-) Andrew. (typing mistakes are mine). Next Generation - H1 -------------------- The next generation of transputer is under development now and is codenamed "H1". Silicon is scheduled for 1Q91 and we have released some preliminary bullet points to give an indication of the performance and features we are planning. - Code compatable with T800. H1 will be able to run all your existing software, making system updates very simple. You will also be able to build systems with mixed H1 and T2/T4 or T8 processors. - Performance will be greater than 100 MIPS and 20 MFLOPS on a single processor giving over five times the performance of existing t800-20 products. - The on-chip memory will be enlarged and operated as on-chip cache to support the performance levels indicated above. - The external memory interface will continue to offer a programmable minimum chip solution for DRAM, SRAM and EPROMs. It will include all the logic required to support new features such as static column and page mode DRAMS. - The serial links on the transputer will support a higher rate and conform to a new protocol to increase communications bandwidth. There will also be hardware support for virtual channels and message passing, thus making the design of networks of transputers more effective and efficient. There will be an interface chip so that the new links can be connected to existing link technology. Further information will be released on this exciting new product during the first half of next year. -- Andrew B Smith Computing Laboratory, The University, Canterbury, Kent.
