Application report detailing implementation of handprinted character recognition using a TMS320C5x DSP on a PCMCIA card in pen-based computers.
This report describes how to implement handprinted character recognition (HCR) using a TMS320C5x DSP on a PCMCIA card in pen-based computers. The system uses a shared architecture among a pen-input processor, the DSP, and a main CPU. The DSP manages character libraries and performs real-time matching. The report also covers system-level software, power management, and communication between components.
The implementation was developed for use in handheld computers, particularly for financial trading applications, and demonstrates how a DSP can be used to offload HCR tasks for faster, more accurate recognition.
The DSP manages pen-stroke and character libraries and performs character-based matching.
A Type II PCMCIA-compatible card, referred to as a DSP/memory card.
The MC68302, an integrated multiprotocol processor.
An operator-trainable stroke-based approach.
