critical registers, resulting in a device that is capable of servicing many asynchronous events with minimal
latency. The device has an 8-level-deep protected pipeline with pipelined memory accesses. This
pipelining enables it to execute at high speeds without resorting to expensive high-speed memories.
Special branch-look-ahead hardware minimizes the latency for conditional discontinuities. Special store
conditional operations further improve performance.
As with many DSC type devices, multiple busses are used to move data between the memories and
peripherals and the CPU. The C28x memory bus architecture contains a program read bus, data read bus
and data write bus. The program read bus consists of 22 address lines and 32 data lines. The data read
and write busses consist of 32 address lines and 32 data lines each. The 32-bit-wide data busses enable
single cycle 32-bit operations. The multiple bus architecture, commonly termed Harvard Bus, enables the
C28x to fetch an instruction, read a data value and write a data value in a single cycle. All peripherals and
memories attached to the memory bus will prioritize memory accesses. Generally, the priority of memory
bus accesses can be summarized as follows:
Highest:
Data Writes
Program Writes
Data Reads
Program Reads
Fetches
(Simultaneous data and program writes cannot occur on the memory bus.)
(Simultaneous data and program writes cannot occur on the memory bus.)
(Simultaneous program reads and fetches cannot occur on the memory bus.)
(Simultaneous program reads and fetches cannot occur on the memory bus.)

To enable migration of peripherals between various Texas Instruments (TI) DSC family of devices, the
F2833x devices 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. Three versions of the peripheral bus
are supported on the F2833x. One version supports only 16-bit accesses (called peripheral frame 2).
Another version supports both 16- and 32-bit accesses (called peripheral frame 1). The third version
supports DMA access and both 16- and 32-bit accesses (called peripheral frame 3).
The F2833x implements the standard IEEE 1149.1 JTAG interface. Additionally, the F2833x supports
real-time mode of operation whereby the contents of memory, peripheral and register locations can be
modified while the processor is running and executing code and servicing interrupts. The user can also
single step through non-time critical code while enabling time-critical interrupts to be serviced without
interference. The F2833x implements the real-time mode in hardware within the CPU. This is a unique
feature to the F2833x, no software monitor is required. Additionally, special analysis hardware is provided
which allows the user to set hardware breakpoint or data/address watch-points and generate various
user-selectable break events when a match occurs.
This asynchronous interface consists of 20 address lines, 32 data lines, and three chip-select lines. The
chip-select lines are mapped to three external zones, Zones 0, 6, and 7. Each of the three zones can be
programmed with a different number of wait states, strobe signal setup and hold timing and each zone can
be programmed for extending wait states externally or not. The programmable wait-state, chip-select and
programmable strobe timing enables glueless interface to external memories and peripherals.
