A Static-Superscalar Controller Core

The Diamond Standard 570T is among the highest performance, highest throughput licensable CPUs available today. It combines an efficient 5-stage pipeline with a 3-issue VLIW architecture, enabling it to obtain leading performance levels on both control and DSP code.

Due to the Diamond 570T's flexible base architecture, 16-, 24-, and compound 64-bit VLIW instruction bundles can be freely intermixed in the instruction stream with no processor mode switching, thus maintaining performance while optimizing code size. The compiler automatically creates 64-bit VLIW instruction bundles if instructions can be issued simultaneously; otherwise, a single 16/24-bit instruction is issued. This capability increases code density to industry leading levels, reducing the amount of on-chip cache or memory required for storage of instructions.

The Diamond 570T includes  many standard DSP instructions that increase the performance of numerically intensive applications, plus a 32x32 multiplier and 32-bit integer divider. Example DSP instructions include: zero overhead looping, clamps (saturating arithmetic), max/min value, normalize, and sign extend. Additionally, a MAC unit enables high performance on inner loops requiring fast multiply accumulate operations.

The Diamond 570T features innovative I/O that allows data to be streamed in and out of the processor without going over the main data bus. The two 32-wire GPIO (general-purpose I/O) ports allow direct control and monitoring of peripherals. Two 32-bit FIFO port interfaces can connect to standard FIFOs for direct, predictable communication with other RTL blocks, devices and processors.
