TMS320C2812 Peripheral Bus
To enable migration of peripherals between various Texas Instruments ( TI?) DSP family of devices, the
F281x and C281x adopt a peripheral bus standard for peripheral interconnect. The peripheral bus bridge
multiplexes the various busses that make up the processor “Memory Bus” into a single bus consisting of
16 address lines and 16 or 32 data lines and associated control signals. Two versions of the peripheral
bus are supported on the F281x and C281x. One version only supports 16-bit accesses (called peripheral
frame 2) and this retains compatibility with C240x-compatible peripherals. The other version supports both
16- and 32-bit accesses (called peripheral frame 1).
