Nowadays USB port is used widely for data transactions between electronic devices and computers. In many scenarios, there is no need to communicate with the USB port directly, therefore electronic designers use USB to UART (RS232-Serial) converter chips,...
I decided to start by implementing Butterworth IIR filters using the fixed point formats below. The first step is to find out how much the limited precision arithmetic will affect the filters. I am not using the PIC32 DSP ligrary because I could not...
Briefly about architecture and instruction set - it is 8-bit design with 8 registers: 000 - 0 (always zero) 001 - A (accumulator) 010 - B 011 - C 100 - D 101 - E 110 - F (flags and 3 higher bits for jumps) 111 - G (8 lower bits of program counter) Flags...
