Feature ADSP-BF592 BLACKFIN PROCESSOR CORE
Timer/Counters with PWM 3 As shown in Figure 2, the Blackfin processor core contains two SPORTs 2 16-bit multipliers, two 40-bit accumulators, two 40-bit ALUs, SPIs 2 four video ALUs, and a 40-bit shifter. The computation units UART 1 process 8-, 16-, or 32-bit data from the register file. Parallel Peripheral Interface 1 The compute register file contains eight 32-bit registers. When performing compute operations on 16-bit operand data, the TWI 1 register file operates as 16 independent 16-bit registers. All GPIOs 32 operands for compute operations come from the multiported L1 Instruction SRAM 32K register file and instruction constant fields. L1 Instruction ROM 64K (bytes) Each MAC can perform a 16-bit by 16-bit multiply in each y L1 Data SRAM 32K cycle, accumulating the results into the 40-bit accumulators. mor L1 Scratchpad SRAM 4K Signed and unsigned formats, rounding, and saturation e M L3 Boot ROM 4K are supported. Maximum Instruction Rate1 400 MHz The ALUs perform a traditional set of arithmetic and logical Maximum System Clock Speed 100 MHz operations on 16-bit or 32-bit data. In addition, many special instructions are included to accelerate various signal processing Package Options 64-Lead LFCSP tasks.
