Для конвертирования используем библиотеки use ieee.std_logic_arith.all; use ieee.std_logic_unsigned.all. Добавили ParallelBusMaster на схему. Изменили условия чтения и записи в блоках с адресным пространством. При 200МГц синхросигнале скорость передачи двух байт (за два такта) уменьшилась до 110 нс.
