A cache memory includes a tag memory array and a data memory array. A control register records a reconfiguration status of at least one cache way, a start address of the tag memory array, and a start address of the data memory array. A memory controller is electrically connected to the tag memory array, the data memory array, and the control register. The memory controller controls a data access state of the tag memory array according to the mode byte and the tag base address. The memory controller controls a data access state of the data memory array according to the mode byte and the data base address. A selection module is electrically connected between the tag memory array, the data memory array, and the memory controller. The cache memory solves the problem of idle tag memory of the tag memory array.

According to one exemplary embodiment of a buffer clearing apparatus for computer graphics, a buffer clearing (BC) hardware agent is configured to interface between one or more system buses and a memory controller, to execute one or more frame buffer clearing operations while performing memory access or power of buffer-related operations at the same time. The BC hardware agent keeps track of a plurality of status to read from and/or write to a frame buffer. When the frame buffer is to be cleared, the BC hardware agent clears a clear tag table. When a background pixel of the frame buffer is to be read, the BC hardware agent returns a background value stored in itself.

The invention relates to a compressed data managing system and method for circular buffer. By using the system and method of the invention, when storing the compressed data in a circular buffer and an event occurs, the hardware compression mechanism can stop immediately, without jeopardizing the decompression of the compressed data. Therefore, the system and method of the invention can overcome the following conventional problem: Conventional real-time tracers need several cycles to write the compressed data into the trace memory, which is unbeneficial to error diagnosis. Since when an error occurs, the system might enter the unstable state, this could cause that the tracers fail to write the last compressed data into the trace memory.

A backward compression system and a backward compression method are provided. By using the system and the method, under limited memory space, a relationship between input data and previous data is identified in real time, the input data or previous data is encoded according to the relationship, and the order of data output is such that the encoded data is output first and the complete data is output second. When the output data is stored in circular memory and the memory gets full, the oldest encoded data is overwritten first, and the complete data is not overwritten until all the related encoded data is overwritten. Therefore, more original data can be preserved after decompression. Thus, system signals can be compressed and utilization of limited memory space can be improved.

Backward compression system and method

The invention relates to an automatic register backup/restore system. The system comprises: a general register file, a backup register file, at least one backup mode signal and at least one selector for selecting the general register file. The general register file comprises a plurality of general registers, and the backup register file comprises a plurality of backup registers. According to the system of the invention, upon exception, a backup mode is determined according to the cause of the exception. Then, according to the determined backup mode, the contents of at least one general register are automatically copied into at least one backup register. Upon leaving the exception process, according to the determined backup mode, the contents of the corresponding general registers are restored from the corresponding backup registers by using at least one selector. Therefore, the system of the invention can reduce the data moving activities between memory and registers during exception process. Because of the single operation mode of the system, the system does not need any selection-mode bit for selecting accessible registers due to different operation modes as used in the prior art. Therefore, the system of the invention can decrease the latency of accessing registers.
