The CYBERPLUS is high speed  scalar  processor  made  of  15
independent  functional  units  that  can  accept data every
machine cycle (1 machine cycle =  20  nanoseconds).   It  is
capable of 650 million instructions per second (this assumes
that you have an application that can use almost all of  the
independent  functional  units  at one time).  The CYBERPLUS
has a floating point option, made  up  of  three  additional
functional  units, capable of 65 MFLOPS with 64 bit floating
point numbers and 103 MFLOPS  with  32  bit  floating  point
numbers.

Each functional unit can provide output to any or all of the
other  functional  units  through  a  crossbar.   There is a
register unit to provide high speed temporary storage but it
is  not  required  when  using a functional unit (you can do
memory to functional unit to memory operations).

Each CYBERPLUS processor  can  connect  to  other  CYBERPLUS
processors  through  a  number of ring interfaces.  The ring
interface provides immediate transfer for the memory of  one
CYBERPLUS  processor to the memory of any one or combination
of other processors on the ring.  The  ring  interface  also
provides  a  indirect  mode which places the data in a queue
state until the designated processor or processors are ready
to process the data.

Each CYBERPLUS has 256K  of  64  bit  high-performance  data
memory.  It is expandable to 512K 64 bit words.  The program
instruction memory is made up  of  4096  200-bit  words.   I
believe  that  the size of the program memory increases with
the floating point option.  I can not remember by how much.

1K = 1024
