For the TMSC Pin PowerPAD plastic quad flatpack, the external . Another key feature of the C67x CPU is the load/store architecture, where all. C DSK Features. • A Texas Instruments TMSC DSP operating at MHz. • An AIC23 stereo codec. • 16 Mbytes of synchronous DRAM. Starter Kit (DSK), based on the TMSC floating point DSP running at MHz. The C processor has KB of internal memory, and can potentially address a pretty good idea of the TMSC architecture and features.

The Codec has 4 channels: Frequency Multiplier using PLL C series[ edit ] Tmsc architecture pocessor family consists of bit microcontrollers with performance integrated peripherals designed for real-time control applications. This means that all of the memory to CPU information transfers can be accomplished in a single cycle: If needed, these registers can also be used to control loops and counters; however, the SHARC DSPs have extra hardware registers to carry processor many of these functions.


These control the addresses sent to the architectufe and data memories, specifying where the information is to be read from or written to. Filter Comparison Match 1: It is used to communicate between Codec and DSP. All downloads to the the kit is done through JTAG it can be understood by all other related configurable chips.

For short this DSP will be. In addition, an abundance of circular buffers greatly simplifies DSP code generation- both for the human programmer as well as high-level language compilers, such as C.

This means that the same set of program instructions will continually pass from program memory to the CPU. There are also many important features of the SHARC family architecture that aren’t shown in this simplified illustration. Download this chapter in PDF format Chapter This is how the signals enter and exit the system.


If it was new and exciting, Von Neumann was there! Tmsc architecture consists of 5 sub-families: This feature allows step 4 on our list managing the sample-ready interrupt to be handled very quickly and efficiently. Multiplying two numbers requires at least three clock cycles, one to transfer each of the three numbers tms320v6713 the bus from the memory to the CPU.

Texas Instruments DSP Processors 6713/ 6416 CCS

One of the biggest bottlenecks in executing DSP algorithms is transferring information to and from memory. Most present day DSPs use this dual bus architecture. To improve upon this situation, we start by relocating part of the “data” to program memory.

Some DSPs have on-board analog-to-digital and digital-to-analog converters, a feature called mixed signal.

Architecture of the Digital Signal Processor

These are extremely high speed connections. However, on additional executions of the loop, the program instructions can be pulled from the instruction cache. Figure a shows how this seemingly simple task is done in a traditional microprocessor. Just as important, dedicated hardware allows these data streams to be transferred directly into memory Direct Memory Access, or DMAwithout having to pass through the CPU’s registers.

For instance, an 80 bit accumulator is built into the multiplier to reduce the round-off error associated with multiple fixed-point math operations.

Since it has VLIW architecture, it can execute up to eight bit instructions per cycle.

In a single clock cycle, data from registers ssp be passed to the multiplier, data from registers can be passed to the ALU, and the two results returned to any of the 16 registers. The idea is to build upon the Harvard architecture by adding features to improve the throughput. The desired amount of multiplication can be obtained by selecting a proper divide by N network,where N is an integer.


A frequency multiplier can be designed using a PLL and a ‘divided by N’ counter. It uses glue logic, meaning that whatever components we want to use, a hardware tie is made between them. This includes datasuch as samples from the arcihtecture signal and the filter coefficients, as well as program instructionsthe binary codes that go into the program sequencer. Osborne Nicolas The McASP also provides extensive error-checking and recovery features, such as the bad clock detection circuit for each high-frequency master clock tmsc architecture verifies that the master tms3200c6713 is within a programmed frequency range.

Since the buses operate independently, program instructions and data can be fetched at the same time, improving the speed over the single bus design.

As an example, suppose you write an efficient FIR filter program using coefficients.


In fact, if we were executing random instructions, this situation would be no better at all. For instance, IIR filters are more stable if implemented as a cascade of biquads a stage containing two poles and up to two zeros. Tms3206713 and Equipments used: This results in slower operation because of the conflict with the coefficients that must also be fetched along this path. In simpler microprocessors this task is handled as an inherent part of the program sequencer, and is quite transparent to the programmer.

Now let’s look inside the CPU.
