- ...operations.
- We use the term
stream processor because the basic units of data on which Cheops
operates are arrays of data accessed in a sequential fashion. Some
authors make a distinction between such a stream-oriented data-flow
model and one in which an individual datum is considered elemental.
See for instance [18].
- ...resources.
- A corollary property is the ability to
perform portions of an algorithm at faster-than-real-time rates within
the limits improsed by the buffer space available.
- ...processors,
- The ability to cascade processors is limited by
the maximum pipeline delay supported by the flood controller in the ultimate
destination. See below.
- ...involved.
- There is a
separate OK channel associated with the processor's connection to the
Nile Buses, but in practice there are generally too few memory banks
available on a processor module for three other transfers to take place
at the same time as a Nile Bus transfer to or from that module.
- ...mode.
- Actually, we are allowed to connect the DCT
processor right to the transpose engines, but for generality we will
maintain the intermediate buffers.
- ...tasks.
- All figures given in this section are for a dataflow
clock of 32MHz.
