Array processor has 64M bytes of data memory

Numerix Corporation has added the Mars-432 array processor to its line of array processors.

The Mars-432 is a 32-bit floating-point array processor designed for use in a variety of medical, seismic, scientific, and signal processing applications. Features of the Mars-432 include add and multiply times of 100 ns, overall computational power of 30M flops, and a time of I.7 ms to compute a 1024-point FFT. Additional features are DMA transfers at l/O bus rates of 20M bytes per second, data memory read or write in 100 ns, and memory paging for uninterrupted processing during l/O transactions. Direct addressability for up to 16M words of data memory and direct access to the internal bus of the Mars-432 are also included in the design.

Two versions of program memory are offered with the Mars- 432. The standard configuration has a program memory with virtual and physical address space of 4K words. The expanded configuration uses a 4K cache memory to extend the total physical memory to 64K words.

Data memory physical address space is 16M words. Data l/O is supported by DMA trans fers into data memory over the entire address space. Data memory page loading allows the user to have zero overhead background loading of data during time-critical program execution. With this form of I /O, no DMA cyclestealing overhead is incurred and uninterrupted processing can occur simultaneously with l/O transfers.

The architecture of the Mars-432 is designed to support software development tools. Special considerations are included, such as FIFO buffers, at appropriate architectural interfaces to simplify the design and maximize the efficiency of a Fortran compiler. Software development tools include a Fortran development system that provides high-level language access to the Mars-432. The FDS consists of a Fortran compiler, linker, and debugging monitor. Also included as software development tools are a macroassembler and diagnostics package.

The price of a standard configuration with 64K words of data memory is in the $80,000$100,000 range, depending on external interfaces and software options. OEM versions are available in the $50,000 range.
