... A powerful program sequencer controls the flow of instruction execution. The sequencer supports conditional jumps, subrou- tine calls, and low interrupt overhead. With internal loop counters and loop stacks, the ADSP-21992 executes looped code with zero overhead; no explicit jump instructions are required to maintain loops. ...

... Program memory can store both instructions and data, permit- ting the ADSP-21992 to fetch two operands in a single cycle, one from program memory and one from data memory. The DSP dual memory buses also let the embedded SHARC core fetch an operand from data memory and the next instruction from pro- gram memory in a single cycle ...

... ROM is located on Page 255 in the DSP memory space map, starting at address 0xFF0000. External (Off-Chip) Memory Each of the off-chip memory spaces of the ADSP-21992 has a separate control register, so applications can configure unique access parameters for each space. The access parameters include read and write wait counts, wait state completion mode, I/O clock divide ratio, write hold time extension, strobe polarity, and data bus width ...

... The bus request feature operates at all times, even while the DSP is booting and RESET is active. The ADSP-21992 asserts the BGH pin when it is ready to start another external port access, but is held off because the bus was previously granted. This mechanism can be extended to define more complex arbitration protocols for implementing more elaborate multimaster systems ...
