Embodiment Construction

[0101] Data encryption and decryption in traditional communication devices typically involves multiple data transfers across the system bus. For example, when decryption is performed, encrypted data is typically first transferred from cache to external memory over the system bus. In the second step, the encryption function decrypts the encrypted data. Encryption functions are typically implemented in peripheral hardware devices that use the system bus to transfer encrypted data from and decrypt data back to external memory. With this configuration, the system bus should be dimensioned at least three times the maximum data rate to provide sustained rates. Additionally, the external memory needs to be able to achieve at least twice the maximum data rate. That is, to obtain the highest data rate of 20Gbit / s means that the system bus needs to be able to handle the data rate of 60Gbit / s, and the external memory needs to be able to handle the data rate of 40Gbit / s. Therefore, the...

Abstract

The present invention relates to a processing device (100), comprising: a cache (102) coupled to a system bus (104); an encryption device (106) coupled to the system bus (104); and an encryption device (106) coupled to the encryption device ( 106) memory (108). The processing device 100 is configured to operate in at least one of a decryption mode and an encryption mode. When said processing device (100) is configured to operate in said decryption mode, said encryption device (106) is configured to: receive encrypted data units directly from said cache (102) via said system bus (104); decrypting the encrypted data unit to obtain a decrypted data unit; and transmitting the decrypted data unit to the memory (108). When the processing device (100) is configured to operate in the encryption mode, the encryption device (106) is configured to: receive a data unit from the memory (108); encrypt the data unit to obtain an encrypted a data unit; and transferring said encrypted data unit directly to said cache (102) via said system bus (104). Furthermore, the invention relates to a corresponding method, computer program and computer program product.

Description

technical field [0001] The invention relates to a processing device and a communication device comprising such a processing device. Furthermore, the invention relates to a corresponding method, computer program and computer program product. Background technique [0002] In next-generation wireless systems such as the 5G system, the data rate is increasingly required, and a data rate of 20Gbit / s for the downlink and 10Gbit / s for the uplink are currently being considered. These requirements place a significant burden on the communication equipment and its ability to process data efficiently. [0003] Data processing in conventional communication devices involves the transfer of large amounts of data between different functions and / or memories within the communication device. These transfers sometimes go over the system bus, which can become a bottleneck when trying to achieve very high data rates. In some configurations, the size of the system bus needs to be three times th...
