Abstract: A data array forming circuit replaces part of software operation in a low bit rate coding system. The circuit includes a memory storing plural kinds of basic data groups, and an address generating circuit generating an address to access the memory. A data array is formed in accordance with input speech data by selectively reading plural kinds of blocks out of the basic data groups according to the address and by combining the plural read blocks containing different quantities of words. Each block contains an arbitrary quantity of word data. In a data sorting circuit to replace part of software operation in a low bit rate coding system, an index corresponding to the data is set with an initial value on initiating the sorting operation, and a value incremented successively from the initial value is set as an index of the next data.

Abstract: A scan converter control circuit includes first and second memories, each having a data write mode and a data read mode which are selected in response to a switching signal so that the first memory is in the data write mode when the second memory is in the data read mode and the first memory is in the data read mode when the second memory is in the data write mode. A write address counter generates a write address which is to be alternately supplied to the first and second memories and generates a write completion signal when the write address becomes equal to a predetermined count value. A read address counter generates a read address which is to be alternately supplied to the first and second memories and generates a read completion signal when the read address becomes equal to a predetermined count value.
