SAM-450
DSP System |
As real-time DSP systems grow, they become
increasingly difficult to manage. I/O data streams are getting faster, requiring
larger and faster storage capacity. High-speed data streams also mandate a
corresponding increase in processing power. Today's DSP systems share a common
requirement for fast I/O ports, fast memory, fast processors, and a real-time operating
system. Designers are faced with the dual challenges of providing these features
without resorting to unreasonably complex architectures. Ideally, a real-time DSP
system would have only a few powerful processors with a large, central shared memory
resource and support the ability for high-level programming in C. The evolution of
computer memory architectures, along with advances in ASIC chip technology, has allowed
Texas Memory Systems to provide these types of systems.

Super
DSP |
Our DSP systems have been designed to offer
super DSP capacity and still keep the computer architecture simple, easy to understand,
and quick to program. The architecture of the SAM-450 emulates a supercomputer
without the supercomputer 'heavy iron' look. It is based on a single high bandwidth
shared memory resource with a few high performance processors. A clean programming
methodology is achieved by writing application programs in C for execution on a scalar
processor (AX2). The application program makes subroutine calls to the S4 vector
processors which perform the intense number crunching necessary in many high-resolution
applications requiring complex scientific algorithms. Our super DSP architecture
combines ease of use while still maintaining a fast-efficient throughput.

The
SAM Executive |
The SAM real-time Executive (SAMEX) runs on
each processor, controlling and synchronizing SAM system operations. SAMEX provides
system functions, multitasking and parallel processing, but eliminates the complexity and
the latency of popular operating systems. It is tuned to perform system operations
quickly and with low overhead.
