Analog Devices ADSP-BF531/ADSP-BF532 Blackfin Embedded Processor Handbook
The handbook describes the ADSP-BF531 and ADSP-BF532 processors, members of the Blackfin family, highlighting their dual‑MAC, multi‑ALU architecture, low‑power design and portable low‑power features. It explains system integration benefits, including a rich set of peripherals such as UART, SPI, two dual‑channel serial ports, timers with PWM, a real‑time clock, watchdog timer and parallel peripheral interface.
Memory architecture is covered in detail, showing up to 84 KB of on‑chip memory (instruction SRAM, data SRAM and scratchpad), external memory options (SDRAM, SRAM, FLASH) and the memory management unit. The document also outlines booting modes, event handling, exception handling and provides extensive timing and electrical specifications.

Questions answered in these manuals
What is the maximum throughput of the asynchronous memory interface?
The maximum throughput is 14.8 MB/s without concurrent bus activity and 8.3 MB/s while concurrent DMA activity is taking place.
Which Blackfin processors does this interface support?
The interface is developed for ADSP-BF531, BF532, and BF533 Blackfin processors.
What is the cycle count for a 32-bit multiply instruction?
The 32-bit by 32-bit integer multiply instruction always takes 3 cycles to complete.
From: Analog Devices ADSP-BF531/532/533 Blackfin Processor Multi-cycle Instructions Latencies Manual
How many cycles does a Call or Jump instruction take?
All call and jump instructions take 5 cycles to complete, provided the target address is an aligned location.
