Intel’s new line of 64-bit
CISC (Complex Instruction Set Computer) CPU (Central Processing Unit)
chips, formerly known as Merced. There are future chips coded named Deerfield and
Madison. It is too costly at present for home machines. It is used mainly for servers
— machines that service multiple requests from a LAN (Local Area Network)
or from the Internet. IBM (International Business Machines) has a 64-bit version of Java that exploits its huge
address space on Win2K. It has a 10-stage pipeline and 128 integer and 128 floating
point registers. Instructions are 41 bits, packed 3 together into 128-bit bundles, with a 5-bit template that encodes the instruction types in each slot. It is a
design, though quite different from the Pentium. The instruction formats are quite
complex, but not quite as complex as the Pentium. It has many instructions for bit
fiddling and interleaving. It has instructions for the compiler to give it
performance hints. Register instructions typically use two operands and a
destination. There are a number of parallel instructions that do two sets of operands
at once. It can also run Pentium 32-bit code. It gives the
programmer considerable control over the pipelines. There is
ECC (Error Correcting Code) on the various busses. It is probably the most
complicated CPU I have yet encountered. You can get the manuals and
datasheets from Intel. The chip is not particularly well-suited to Java, since it has
no 32-bit operations, required to support integer
arithmetic and the Java stack. Everything is 64-bit. For
Java to work well on it, you would need to convert your ints to longs. The Itanium II
(code named McKinley) 1 GHz processor retails for
Clearly these are not yet for the home market. Customers must need the huge 64 bit
address spaces to justify such prices.
HP (Hewlett Packard) makes a 64-bit JDK for the Itanium and HP-UX.
