Homework 3 - Hardware-accelerated bit-transpose on MSP-430.
Introduction The openMSP430 is a synthesizable 16bit microcontroller core written in Verilog. It is compatible with Texas Instruments' MSP430 microcontroller family and can execute the code generated by any MSP430 toolchain in a near cycle accurate way. The core comes with some peripherals (16x16 Hardware Multiplier, Watchdog, GPIO, TimerA, generic templates), with a DMA interface, and most.In this homework, you have to design a bit-transpose coprocessor. The coprocessor reads in a 8-by-8 bit-matrix, computes the matrix transpose, and returns the result. You will receive a reference implementation of the algorithm in software, implemented on an MSP430 core. Your job is to accelerate a C function call of that reference.The program code represents two instructions. If the program counter was initialized to 0xF000 and the CPU unleashed, what effect would the first two instructions have on the MSP430 ports? Specifically which port is modified and how? (Hint: Look at the MSP430 User's Guide to determine what addresses are assigned to the ports.) (4 points).
This homework will test your understanding of basic MSP430 programming. It will require you going through the datasheet and users guide (see MSP430FR59xx Family User's Guide) to find the information you need, and will test your understanding of how to work with registers, and the function of various important peripherals in the MSP430.The MSP430 is a little byte-endian device (see section 2.3 of the MSP430 ABI for more details). This means that if the first byte in the memory dump is actually the least significant byte and the next byte is the most significant byte if storing a standard 16-bit word, as the stack pointer does. If you are storing only a byte, endianness does not apply. So in this case, we can see the first.
MSP430 Programming Via the Bootstrap Loader The MSP430 BSL enables users to communicate with embedded memory in the MSP430 microcontroller during the prototyping phase, final production, and in service. Both the programmable memory (flash memory) and the data memory (RAM) can be modified as required. Do not confuse the bootstrap loader.
